In the description of the embodiments of the present application, "/" means or is meant unless otherwise indicated. For example, A/B may represent A or B. The "and/or" in the present application is merely one association relationship describing the association object, indicating that three relationships may exist. For example, a and/or B may represent: a exists alone, A and B exist simultaneously, and B exists alone. "at least one" means one or more. "plurality" means two or more than two.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the described embodiments of the application may be combined with other embodiments.

Different terminal devices include various forms, such as mobile phones, tablets, and folding machines, which have large differences. Because of the morphological differences of the terminal devices, there are also large differences between the corresponding screen parameters such as screen size, resolution, aspect ratio, etc. In order to reduce the difficulty of developing an application program, a developer of the application program generally sets a layout file of an application interface according to widely used screen parameters on the market, and does not set a layout file of the application interface corresponding to all the screen parameters. The layout files of the same application interface may have differences in application interfaces that may be displayed on different terminal devices. For example, the layout file of an application interface may completely display the application interface on the terminal device that is adapted to the application interface, but the layout file of the application interface may have an abnormality in the application interface that is displayed on the terminal device that is not adapted to the application interface, such as a problem that the page is not fully displayed, the field of view of the scene is small, and the display is abnormal.

Fig. 1 is a schematic view of a scenario displayed by an application interface. For example, as shown in fig. 1 (a), the application interface of the game is displayed normally on the left terminal device, but displayed abnormally (e.g., cannot be displayed completely) on the right terminal device. Compared with the application interface displayed in the left terminal equipment, the application interface displayed in the right terminal equipment has the problem of small field of view of the scene, and the displayed scene content is less. For example, as shown in fig. 1 (a), the resolution in the screen parameters of the terminal device is 2400×1920. After the application program obtains the picture layout resource corresponding to the generated application interface, the length and width of the picture layout resource are subjected to equal-ratio stretching by taking the screen width in the screen parameter as a reference, namely 1920 as a reference, and the picture layout resource is amplified to 4267 multiplied by 1920. However, since the screen length of the terminal device is 2400, the left and right parts of the screen in the screen layout resource cannot be completely displayed after the screen layout resource is stretched, and there is a partial defect. As shown in fig. 1 (b), the application interface of the learning application is displayed normally on the left terminal device, but is displayed abnormally on the right terminal device. Compared with the application interface displayed in the left terminal equipment, the application interface displayed in the right terminal equipment has the problem of incomplete page display, only partial pages are displayed, and the specific contents in the middle table are not clearly seen.

In order to avoid the situation that the page layout of an application interface cannot be adapted to display screens of terminal equipment with different sizes, shapes and resolutions, and the display effect of the application interface is poor, the embodiment of the application provides an application interface display method. In an embodiment, the second screen resolution may not be the real screen resolution of the screen of the terminal device, and the embodiment of the application can enable the terminal device to generate the corresponding application interface for display according to the second screen resolution, so that the situation that the display effect corresponding to the application interface generated according to the real screen parameters of the display screen is poor due to the fact that the page layout of the application interface cannot be matched with the display screen of the terminal device is avoided, the display layout of the application program in different terminal devices is consistent and comfortable, and the abnormal display situation of the application interface is improved.

The application interface display method provided by the embodiment of the application is applied to the terminal equipment. By way of example, the terminal device may be a handheld device or the like, such as a mobile phone, tablet, palmtop, notebook, ultra mobile personal computer, netbook, personal digital assistant (personal digital assistant, PDA), wearable device or the like, that may install and run an application, and the embodiments of the present application are not limited in this regard.

In order to better explain the application interface display method provided by the application, some nouns are explained.

A Pixel (PX) is a basic unit of image display. Each pixel may have a respective color value and may be displayed in three primary colors, for example, an RGB color gamut consisting of three colors of Red (Red, R), green (Green, G), blue (Blue, B), or a CMYK color gamut consisting of cyan (C), magenta (M), yellow (Y), and black (K). An image is a collection of individual pixels, and typically, the more pixels per unit area represent the higher resolution, the closer the displayed image will be to a real object. On the terminal device, the number of pixels can be divided into a horizontal number of pixels and a vertical number of pixels. The number of horizontal pixels indicates the number of pixels contained in the horizontal direction, and the number of vertical pixels indicates the number of pixels contained in the vertical direction.

Screen size represents the physical size of the terminal device screen, which may be expressed in terms of the length of the diagonal of the screen, in inches, 1 inch = 2.54 cm, such as 3.5 inches, 4.2 inches, 5.0 inches, 5.2 inches, 5.5 inches, 6.0 inches, etc. typical cell phone screen sizes, 15.6 inches, 20.0 inches, 27.0 inches, etc. typical computer display screen sizes.

The screen resolution refers to the physical resolution of the display screen of the terminal equipment, and can be used for indicating the number of horizontal physical pixels of the screen x the number of vertical physical pixels, and the screen resolution is expressed by pixels (px). The screen resolution is a hardware feature, is a basic unit of a display composition picture, and is not changeable. Screen resolution is typically expressed in terms of width and height, e.g., 1920 x 1080, with 1920 a px width and 1080 a px height. The higher the screen resolution, the more abundant the amount of image information that can be displayed by the screen of the terminal device, and the more detailed the picture. The common screen resolutions of the terminal devices are 720P (1280×720), 1080P (1920×1080), 2K (2560×1440), and the like.

The screen pixel density (PPI x els per inch, PPI) may be used to represent the number of physical pixels per inch of the display screen of the terminal device. PPI describes the number of pixels of the display screen itself, which is an inherent hardware physical property of the display screen, and is not changeable. The higher the PPI is, the higher the density of the display screen can be used for displaying images, so that the definition and fineness of the screen are improved, and the fidelity is improved.

In one embodiment of the application, the screen pixel density may be calculated based on the screen resolution and screen size.

The calculation formula of the screen pixel density is as follows:

wherein W and H are the width and height of the display resolution; d is the diagonal dimension of the display screen in inches.

Display pixel Density (DPI) refers to the number of pixels that can be sampled, displayed, and output per inch. DPI describes the pixel density at which the terminal device displays, a software attribute that can be configured. Before the terminal equipment leaves the factory, the terminal manufacturer can pre-configure the DPI so that the terminal equipment displays based on the DPI configured by default. In an embodiment of the present application, when the terminal device is a tablet, the DPI may be configured to be 1.3 or 1.4 times its PPI by default before the device leaves the factory; when the terminal device is a mobile phone, the DPI may be configured to be 1.2 times as large as its PPI by default before the device leaves the factory. In an embodiment of the present application, the same DPI may be set for a plurality of terminal devices having different PPI but the same or similar device types, so as to reduce display differences of the same application program on different terminal devices. For example, both cell phone a with PPI 321 and cell phone B with PPI 306 may be set to 320DPI. DPI is related to image size and image resolution. The DPI currently set by the terminal device may be determined based on the number of pixels and the physical size of the image. The ratio of the number of pixels of the image to the physical size may be determined as DPI. In the case of the same image size, the higher the image resolution, the greater the DPI; in the case of the same image resolution, the smaller the image size, the larger the DPI. The higher the DPI value, the sharper the image. In an embodiment of the application, when the screen size and the screen resolution of the terminal equipment are unchanged, DPI becomes larger, and elements in an application interface displayed by the terminal equipment occupy more pixel points, so that the effect of amplifying the application interface is realized; DPI reduces, elements in an application interface displayed by the terminal equipment occupy fewer pixel points, and the effect of reducing the application interface is realized.

Different screen density levels may be used to represent different ranges of display pixel densities, such as ldpi, mdpi, hdpi, xdpi, xxdpi, xxxdpi, nodpi. Wherein ldpi is suitable for the resources of the low density screen; mdpi is suitable for the resources of the medium density screen, and is the reference density of some operating systems; the hdpi is suitable for the resources of the high-density screen; the xdpi is suitable for the resources of the ultra-high density screen; xxdpi is suitable for resources of ultra-high density screens; the xxxdpi is suitable for the resources of the ultra-high density screen; nodpi applies to resources of all density screens. These are density independent resources. Whatever the density of the current screen, the system will not scale the resources marked with this qualifier. Table 1 is the correspondence of some screen density levels to display pixel density ranges.

TABLE 1

When the terminal equipment displays an application interface of the application program, the most suitable resource file is automatically selected for display according to the display pixel density of the terminal equipment and the resource file provided by a developer. The developer of the application may create different subfolders (e.g., a drawable folder) under the Resources folder of the application, with different qualifiers marking different screen density levels, such as drawable-mdpi, drawable-hdpi, drawable-xhdpi, and the like. Resource files of the corresponding resolution are then placed under each subfolder. When the application program generates the application interface, firstly, the display pixel density of the terminal equipment is obtained, and the screen density grade corresponding to the display pixel density is determined, for example, according to table 1, the screen density grade corresponding to the display pixel density is retrieved. After determining the screen density level corresponding to the display pixel density, the application program obtains the corresponding resource file from the available folder corresponding to the screen density level. For example, if the screen resolution of the display screen of a certain terminal device is 1080×1920, the screen pixel density is 400dpi, and assuming that the size of a picture in the application resource file is 270×480 pixels, according to table 1, it can be determined that the screen density level corresponding to 400dpi is xxhdpi, and the system will automatically preferentially search the corresponding picture in the drawable-xxhdpi folder. If the corresponding picture is retrieved, loading is performed, and at this time, the picture is displayed on the display device with the size of the picture itself, that is, 270×480 pixels. In an embodiment of the present application, if the developer does not provide the picture corresponding to the screen density level of the terminal device, the terminal device retrieves the corresponding picture from the other screen density levels. For example, in the above example, if no corresponding picture is retrieved in the drawable-xxxhdpi folder, the terminal device will retrieve from the folder drawable-xxxhdpi having the higher screen density level, and if no corresponding picture is retrieved from the folder having the highest screen density level, find the drawable-nodpi folder. If no corresponding picture is searched in the drawable-nodpi folder, starting to search the folders with low resolution in sequence, and searching the ldpi from high to low until the corresponding picture is searched, namely starting to search from the drawable-xhdpi folder.

In an embodiment of the present application, if the screen density level of the resource file acquired by the terminal device is different from the screen density level of the terminal device, the terminal device scales the resource file according to a certain proportion. For example, when the screen density level of the terminal device is hdpi and the screen density level of the acquired picture is mdpi, the terminal device enlarges the resource file. For another example, when the screen density level of the terminal device is hdpi and the screen density level of the acquired picture is xhdpi, the terminal device may reduce the resource file. In some embodiments, the scaling factor may be expressed as: mdpi: hdpi: xhdpi: xxhdpi: xxxhdi=1:1.5:2:3:4.

Density independent pixels (density independent pixels, dp), also known as Density independent pixels, can be automatically scaled according to the pixel density of the current screen to keep the physical size of the view unchanged on different screens. The pixel density refers to how many pixels are on the screen per square inch, denoted by dpi (dots per inch). The density independent pixels refer to the length of 1 pixel when the display pixel density of the display screen is 160 dpi. The density independent pixels need to be converted to pixels for display. The conversion formula between dp and px is: px=dp (dpi/160), when the display pixel density of the display screen is 320dpi, 1 dp=2px, and so on. Lines of the same pixel length occupy different proportions on two terminal devices of the same display pixel density but different screen resolutions. For example, the display pixel density of both terminal apparatuses is 160dpi, and a line of 320px is drawn in the direction parallel to the display screen width, and the line is displayed as a screen width of 2/3 on a terminal apparatus having a screen resolution of 480×800, and as a screen width of 1 on a terminal apparatus having a screen resolution of 320×480, that is, from the left side of the screen width to the right side of the screen width.

The term "User Interface (UI)" in the embodiment of the present application is a media interface for interaction and information exchange between an application program or an operating system and a user, and it implements conversion between an internal form of information and a form acceptable to the user. A commonly used presentation form of the application interface is a graphical application interface (graphic user interface, GUI), which refers to an application interface related to computer operations that is displayed in a graphical manner. The method can be an interface element such as an icon, a window, a control and the like displayed in a display screen of the terminal equipment, wherein the control can comprise a visible interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget and the like.

The application interface display method provided by the embodiment of the application is further described in detail below with reference to the accompanying drawings.

Fig. 2 is a schematic view of a scene of an application interface display according to an embodiment of the present application. As shown in fig. 2 (a), the desktop is displayed on the terminal device at a first screen resolution, which is the real screen resolution of the terminal device screen. An application icon of at least one application program is displayed on the desktop. If the user clicks the application icon of the application program on the desktop, the starting of the application program can be triggered. In the starting process, the application program sends a screen parameter acquisition request to the window manager to acquire the screen parameters of the terminal equipment. After the application program obtains the screen parameters of the terminal equipment, based on the obtained screen parameters and the picture layout resources, a corresponding application interface is constructed, wherein the size of the application interface is consistent with the size of the screen parameters. As shown in fig. 2 (a), the user clicks an icon of the game application. In response to a user clicking the icon, the game application sends a screen parameter acquisition request to the window manager to acquire screen parameters of the terminal device. The terminal equipment receives a screen parameter acquisition request sent by the game application and determines whether the game application is a preset target application. The window manager determines that the game application is a target application, acquires a second screen resolution corresponding to the game application, and sends the second screen resolution as a target screen parameter to the game application, wherein the second screen resolution is not the real screen resolution of the screen of the terminal device. After the game application receives the second screen resolution, a corresponding application interface is constructed based on the acquired second screen resolution and the picture layout resource, wherein the size of the application interface is consistent with the size of the second screen resolution. When the terminal device displays the desktop as shown in fig. 2 (a), the desktop is displayed on the terminal device in a full screen, and when the application interface of the game application is displayed as shown in fig. 2 (b), the application interface is displayed only on a part of the screen of the terminal device and is not displayed in a full screen. Some specific implementations of the application interface display shown in fig. 2 may be found below.

Fig. 3 is a schematic view of another scenario displayed by an application interface according to an embodiment of the present application. As shown in fig. 3 (a), the desktop is displayed on the terminal device at a first screen resolution, which is the real screen resolution of the terminal device screen. As shown in fig. 3 (a), the user clicks on an icon of the video application. In response to a user clicking an application icon, the video application sends a screen parameter acquisition request to the window manager to acquire screen parameters of the terminal device. And the terminal equipment receives a screen parameter acquisition request sent by the video application and determines whether the video application is a preset target application or not. And if the window manager determines that the video application is not the target application, the window manager sends the first screen resolution to the video application as a target screen parameter. After the video application receives the first screen resolution, a corresponding application interface is constructed based on the acquired first screen resolution and the picture layout resource, wherein the size of the application interface is consistent with the size of the first screen resolution. As shown in fig. 3 (b), after the video constructs its corresponding application interface, the application interface corresponding to the video application may be displayed on the terminal device according to the first screen resolution. As shown in fig. 3 (a), when the terminal device displays the application interfaces of the desktop and the video application, the application interfaces of the desktop and the video application are all displayed on the terminal device in full screen. Some specific implementations of the application interface display shown in fig. 3 may be found below.

Fig. 4 is a schematic view of a scene of another application interface display according to an embodiment of the present application. As shown in fig. 4 (a), an application interface of a video application is displayed on a terminal device at a first screen resolution, which is a real screen resolution of a screen of the terminal device. The application interface of the video application includes a launch control of the gaming application. As shown in fig. 4 (a), clicking on the launch control of the game application by the user may trigger the launch of the game application. During the starting process of the game application, a screen parameter acquisition request is sent to the window manager to acquire the screen parameters of the terminal equipment. The terminal equipment receives a screen parameter acquisition request sent by the game application and determines whether the game application is a preset target application. The window manager determines that the game application is a target application, acquires a second screen resolution corresponding to the game application, and sends the second screen resolution as a target screen parameter to the game application, wherein the second screen resolution is not the real screen resolution of the screen of the terminal device. After the game application receives the second screen resolution, a corresponding application interface is constructed based on the acquired second screen resolution and the picture layout resource, wherein the size of the application interface is consistent with the size of the second screen resolution. When the terminal device displays the video application as shown in (a) of fig. 4, the video application may be displayed on the terminal device in full screen, and when the game application is displayed as shown in (b) of fig. 4, the game application is displayed on only a part of the screen of the terminal device and is not displayed in full screen. Some specific implementations of the application interface display shown in fig. 4 may be found below. Fig. 5 is a flowchart of an application interface display method according to an embodiment of the present application. The method is applied to terminal equipment, and the terminal equipment comprises an application program and a window manager. The order of the steps in the flowchart may be changed and some steps may be omitted according to various needs.

301, an application program sends a screen parameter acquisition request to a window manager.

In an embodiment, the application program may be any type of application installed on the terminal device, for example, a game application, such as a queen glory. When a user opens an application, the application sends a screen parameter acquisition request to the window manager. The screen parameter acquisition request is used for acquiring screen parameters of the terminal device. Screen parameters may include, but are not limited to: screen resolution, display pixel density, etc.

When using the terminal device, the user may open one application installed by the terminal device in a variety of ways, e.g., click on an application icon on a desktop, click on a notification message for an application in a message notification bar, click on a launch control in another application, etc.

In one embodiment of the application, the terminal device displays the desktop at a first screen resolution, which is the true screen resolution of the terminal device screen. The desktop comprises application icons corresponding to at least one application program. After a user clicks an application icon, an input management module in the terminal equipment can identify the clicking operation of the user and report the clicking operation to a desktop; the desktop may determine the clicked application icon according to the clicking operation of the user, determine the application corresponding to the clicked application icon, and notify the activity management service (ActivityManagerService, AMS) to start the clicked application. The AMS may launch the Activity of the clicked application. In one embodiment of the present application, after the Activity of the application is started, the Activity of the application sends a screen parameter acquisition request to the window manager.

In another embodiment of the present application, the terminal device displays an application interface of a first application at a first screen resolution, and the first application may be any one of application programs installed in the terminal device, such as a video application. The application interface of the first application comprises a start control of a second application, and the second application can be any application program installed in the terminal equipment, such as a game application. The enable control is used to launch a second application. When the user clicks the start control of the second application, the first application sends a request for starting the second application to the AMS, and a start event of the second application is triggered, so that the AMS starts the Activity of the second application. After the AMS starts the Activity of the second application, the Activity of the second application sends a screen parameter acquisition request to the window manager.

In one embodiment of the present application, after an application is started, the AMS may send a window start notification to the window manager, where the window start notification carries an application identifier of the application. After receiving the notification, the window manager can create a window corresponding to the started application program according to the carried application identifier.

The window manager determines whether the application is the target application 302.

The target application is an application program which needs to be displayed using preset screen parameters, namely, an application program which is displayed using the real screen resolution of the screen of the non-terminal device.

In an embodiment of the present application, the target application may be preset or updated with modifications. For example, before the terminal device leaves the factory, the terminal manufacturer may determine, as the target application, an application program that is likely to be out of fit with the terminal device. In an embodiment of the present application, the terminal device may determine the target application based on the push information sent by the cloud server. The push information comprises application information of application programs which are not matched with the size of the terminal equipment. The application information is used to determine an application program, such as an application package name. The cloud server may be a server corresponding to the terminal manufacturer. When a terminal manufacturer discovers a new application program which is not matched with the size of the terminal equipment, push information is generated, and the generated push information is sent to a terminal server.

In an embodiment of the application, the target application may also be determined based on the user's settings. In one embodiment of the present application, after a user installs an application, the operating system may generate a parameter setting control for the application at a screen parameter setting in the setting of the terminal device. When the user clicks the parameter setting control of an application program, the screen parameter setting corresponding to the application program can be displayed. The target application may be determined based on the operation of the parameter setting control of the application program. Referring to fig. 6, a schematic diagram of a parameter setting control according to an embodiment of the present application is shown. As shown in fig. 6, the screen parameter settings include an option for the first screen resolution. For example, if the user sets a screen parameter of an application to a first screen resolution based on a parameter setting control of the application, determining that the application is not a target application; if the user sets the control based on the parameters of the application program, the screen parameters of the application program are set to other resolutions than the first screen resolution, which may be simply referred to as application display resolution, and the application program is determined to be the target application. For example, as shown in fig. 6, when the user sets the screen parameter of the application program to recommended resolution 1 (recommended resolution 2), the application program is determined as the target application; when the user sets the screen parameter of the application program to a self-defined resolution which is different from the first screen resolution, the application program is determined as the target application. In an embodiment of the present application, after a user installs an application, the screen parameter of the application may be set to the first screen resolution by default. In an embodiment of the present application, after the user clicks on the custom option, an input box may be displayed, and the user may input the custom resolution in the input box. In one embodiment of the present application, the user may enter custom resolution and DPI parameters within the input box.

In an embodiment of the present application, after a user installs an application, the terminal device may determine, based on a resource file of the application, a picture resource resolution of the application; and displaying the recommended resolution corresponding to the application program on the parameter setting control of the application program based on the picture resource resolution. The picture resource resolutions are in one-to-one correspondence with the recommended resolutions, and the picture resource resolutions are equal to the corresponding recommended resolutions in size. The screen resource resolution refers to the resolution of resource files (e.g., pictures, icons, backgrounds, etc.) provided by the developer to the application. The developer may provide the application with a plurality of resource files of different picture resource resolutions to adapt to different screen density levels of the terminal device. When the download package of an application program downloaded by the terminal device may include one or more resource files with different picture resource resolutions corresponding to the application program. When the download package of an application program downloaded by the terminal device includes resource files of two different picture resource resolutions corresponding to the application program, as shown in fig. 6, two options of recommended resolutions corresponding to the two picture resource resolutions can be displayed on the parameter setting control of the application program.

If it is determined that the application is not the target application, step 303 is executed, where the window manager determines the target screen parameter according to the first screen resolution.

The target screen parameter is a screen parameter returned to the application program by the window manager in response to the screen parameter acquisition request of the application program. In one embodiment of the application, the target screen parameters may include screen resolution, display pixel density. The target screen parameter may be determined based on the first screen resolution and a DPI of a default configuration of the terminal device. For example, the DPI of the default configuration of the terminal device is 320DPI, the first screen resolution is 2400×1920, 2400×1920 is determined as the screen resolution in the target screen parameter, and 320DPI is determined as the target screen parameter. In another embodiment of the present application, the target screen parameter may include only screen resolution. The target screen parameter may be determined based on the first screen resolution. For example, the first screen resolution is 2400×1920, and 2400×1920 is determined as the screen resolution in the target screen parameter.

If the application program is determined to be the target application, step 304 is executed, where the window manager determines a second screen resolution corresponding to the application program, and determines the target screen parameter according to the second screen resolution.

For example, the first screen resolution is 2400×1920, the second screen resolution corresponding to the application program is 2400×1080, and the target screen parameter is determined from 2400×1080, for example, 2400×1080 is determined as the resolution in the target screen parameter.

Each target application includes its corresponding second screen resolution. Fig. 7 is a schematic diagram of an application interface display method according to an embodiment of the present application. As shown in fig. 7, each target application has its corresponding second screen resolution. The second screen resolution is not the true screen resolution of the terminal device screen, and the second screen resolution is less than the first screen resolution. Different target applications may correspond to the same or different second screen resolutions. In an embodiment of the present application, before the terminal device leaves the factory, when determining the target application, the terminal manufacturer may configure the second screen resolution corresponding to the target application. In an embodiment of the present application, when a new target application is detected, a terminal manufacturer may push application information of the new target application and a second screen resolution corresponding to the target application to a terminal device based on a cloud server.

The second screen resolution of a target application may be determined based on the frame resource resolution of the target application. Some specific descriptions about picture resource resolution can be found above. When only one screen resource resolution exists for a target application and the screen resource resolution is smaller than the first screen resolution, the screen resource resolution may be determined as the second screen resolution of the target application. For example, if the target application is a game and the first screen resolution is 2400×1920, when the screen resource resolution of the game is only 2400×1080, 2400×1080 is determined as the second screen resolution corresponding to the game. When a target application has a plurality of picture resource resolutions smaller than the first screen resolution, the picture resource resolution with the smallest difference with the first screen resolution can be determined first, and the determined picture resource resolution is used as the second screen resolution of the target application. For example, if the target application is video and the first screen resolution is 2400×1920, when the screen resource resolution of the video is 1900×720 and 2400×1080, 2400×1080 can be determined as the second screen resolution corresponding to the video.

In an embodiment of the present application, the second screen resolution corresponding to the target application may be determined based on the selection of the user. When a user sets a screen parameter of an application to an application display resolution, the application display resolution may be determined to be a second screen resolution of the application. For example, as shown in fig. 6, when the user selects the recommended resolution 1, the recommended resolution 1 is determined as the second screen resolution of the application; when the user selects the recommended resolution 2, determining the recommended resolution 2 as the second screen resolution of the application program; when the user selects the customization, the user-defined resolution is determined as the second screen resolution of the application.

In an embodiment of the present application, if it is determined that the second application is the target application, determining the target screen parameter according to the second screen resolution corresponding to the second application.

In one embodiment of the application, the target screen parameters may include screen resolution, display pixel density. In an embodiment, the target screen parameter may be determined based on the second screen resolution and a default configuration of the DPI of the terminal device. For example, the DPI of the default configuration of the terminal device is 320DPI, the second screen resolution of an application program is 2400×1080, 2400×1080 is determined as the screen resolution in the target screen parameter, and 320DPI of the default configuration is determined as the target screen parameter. In another embodiment, when the user inputs the DPI corresponding to an application program in a customized manner, such as when the user inputs the DPI based on the parameter setting control as shown in fig. 6, the target screen parameter may be determined based on the second screen resolution of the application program and the DPI customized by the user. For example, the default configuration of the terminal device has a DPI of 320DPI and a second screen resolution of 2400×1080, the application program custom defines the DPI as 280DPI, determines 2400×1080 as the screen resolution in the target screen parameter, and determines custom defined 280DPI as the display pixel density in the target screen parameter.

In another embodiment of the present application, the target screen parameter may include only screen resolution. The target screen parameter may be determined based on the second screen resolution. For example, the second screen resolution is 2400×1920, and 2400×1920 is determined as the screen resolution in the target screen parameter.

The window manager sends 305 the target screen parameters to the application.

306, the application program constructs an application interface view according to the target screen parameters and the picture layout resources.

In one embodiment of the application, an application may obtain a Resource object, which is a global object within an application process that is used to access Resources of the application, such as a screen layout Resource, through getResource (). In another embodiment, the file under the specified file path may be read by getAsset () acquisition assayManger, acquiring the screen layout resource.

And the application program acquires a layout file corresponding to the target screen parameter from the picture layout resource, and constructs an application interface view according to the acquired layout file. The resolution size of the constructed application interface view is the same as the resolution size in the target screen parameters. In an embodiment of the present application, the application interface view may be a top level view (view) corresponding to the application program.

307, the application sends the application interface view to the window manager.

308, the window manager displays the application interface of the application program according to the application interface view.

In an embodiment of the present application, after receiving the application interface view, the window manager draws the application interface view in a window corresponding to the application program, so as to obtain an application interface of the application program.

In an embodiment of the application, the window manager may centrally display the application interface of the application program on the display screen of the terminal device. In some embodiments of the present application, the alignment position of the window is specified by the gradient attribute in the window parameter (windows manager. Layoutparameters) of the window corresponding to the application program, so that the window is centrally displayed. In another embodiment of the application, x, y may be set in the window parameters to define the screen coordinates of the upper left corner of the window. For example, the default values corresponding to x and y in the window parameters are all 0, and after the application program is determined to be the target application, the values of x and y in the window parameters corresponding to the window are modified, for example, x may be set to 0, y may be set to 480, so that the screen coordinates of the upper left corner of the window are set from (0, 0) to (0, 480), so that the application interface of the application program is centrally displayed. Fig. 8 is a schematic view of a window display scene according to an embodiment of the present application. As shown in fig. 8, when the default values corresponding to x and y in the window parameters are all 0, the window starts to be displayed from the upper left corner of the display screen of the terminal device; when x is set to 0 and y is set to 480 in the window parameter, the window starts to be displayed from (0, 480) of the display screen of the terminal device, so that the application interface of the application program is centrally displayed.

Since the second screen resolution is smaller than the first screen resolution, the application interface of the application program is not displayed on the display screen of the terminal device in full screen when the application program is displayed with the second screen resolution. As shown in fig. 8, when the application interface of the application program is displayed with the second screen resolution, the application interface is not displayed in full screen, and a screen margin exists outside the application interface, that is, the screen margin of the application interface is a screen margin of upper and lower sides (upper side and lower side). Fig. 8 illustrates a screen margin, which may actually further include: one of the upper screen margin, the lower screen margin, the left screen margin and the right screen margin can also comprise any two or more screen margin combinations of the screen margins, such as an upper left screen margin (upper side and left side), an upper right screen margin (upper side and right side), a left and right screen margin (left side and right side), and an upper and lower left screen margin (upper side and left side and lower side). In some embodiments of the present application, x, y may be modified in the window parameters to change the screen-side situation outside the application interface. For example, as shown in fig. 8, the screen coordinates of the upper left corner of the window are (0, 480), and if the screen coordinates of the upper left corner of the window are replaced with (0, 0) from (0, 480), the screen margin of the application interface is changed from the upper screen margin to the lower screen margin. In an embodiment of the present application, no content may be displayed at the screen margin, i.e., the corresponding screen region at the screen margin is in an unlit state; or, a fixed picture, such as a preset solid-color image, can be displayed at the left edge of the screen; alternatively, the desktop may be displayed at the screen margin, such as displaying a portion of the icons on the desktop, which may be application icons that have been recently used by the user. After clicking the application icon displayed at the left edge of the screen, the user can start the icon corresponding to the application program and display the application interface corresponding to the application program. According to the embodiment, when an application program obtains a screen parameter obtaining request from a window manager, whether the application program is a target application is judged, when the application program is the target application program, the second screen resolution of the application program is determined, the second screen resolution is determined to be the resolution in the target screen parameter, the second screen resolution is sent to the application program, so that the application program displays the corresponding application interface according to the second screen resolution, the application interface of the application program is adapted to the display screen of the terminal device, the application interface corresponding to the application program can be displayed more completely, and the display effect of the application interface is good.

All information in the picture layout resource can be completely displayed by displaying the application interface of the application program with the second screen resolution, but since the second screen resolution is smaller than the first screen resolution, when the application interface is displayed with the second screen resolution, more edges can be left on the screen of the terminal equipment. In order to reduce screen margin on a screen of terminal equipment, the embodiment of the application provides an application interface display method. Fig. 9 is a flowchart of an application interface display method according to an embodiment of the present application. The method is applied to terminal equipment, and the terminal equipment comprises an application program and a window manager. The order of the steps in the flowchart may be changed and some steps may be omitted according to various needs.

The application sends 401 a screen parameter acquisition request to the window manager.

The window manager determines 402 whether the application program is a target application.

If it is determined that the application is not the target application, step 403 is performed, where the window manager determines the target screen parameter according to the first screen resolution.

If it is determined that the application is the target application, step 404 is executed, where the window manager determines the second screen resolution corresponding to the application.

Some embodiments of steps 401-404 may be found in the description above regarding steps 301-304 of fig. 5.

405, obtaining a field control parameter.

The visual field control parameter is used for regulating and controlling the display size of an application interface of the target application displayed by the terminal equipment. For example, the visual field control parameter is larger, and the application interface of the target application displayed by the terminal equipment is also larger; the visual field control parameter is smaller, and the application interface of the target application displayed by the terminal equipment is smaller. The field control parameter increases, and the application interface of the target application displayed by the terminal device also increases.

In an embodiment of the present application, the view control parameter may be set to any one value within the [0,1] interval, such as 0.1, 0.5, 0.7, etc. In an embodiment of the present application, the value of the view control parameter may be set to 0 by default. The user can set the values of the field of view control parameters as desired. For example, the user may change the value of the view control parameter by moving the view control stick. Fig. 10 is a schematic diagram of a visual field control push rod according to an embodiment of the present application. As shown in fig. 10 (a), the moving field control push bar may be displayed in a drop down menu of the terminal device. As shown in fig. 10 (a), the control pushrod is moved leftward, and a larger value of the visual field control parameter can be obtained; the push rod is controlled to move rightwards, so that smaller values of the vision control parameters can be obtained. As shown in fig. 10 (b), when the user presses the volume down key of the terminal device, the media volume adjusting push rod, the visual field control push rod, and the alarm volume adjusting push rod may be simultaneously displayed. As shown in fig. 10 (b), the control plunger is moved upward, and a larger value of the view control parameter can be obtained; the push rod is controlled to move downwards, so that smaller values of the vision control parameters can be obtained. Fig. 10 shows an operation schematic of two kinds of view control pushrods by way of example only, and is not limited to this in practical application.

406, determining a third screen resolution according to the second screen resolution and the field of view control parameter; and determining a target screen parameter according to the third screen resolution.

Referring to fig. 11, fig. 11 is a schematic diagram of an application interface display according to an embodiment of the present application. As shown in fig. 11, a third screen resolution is determined based on the first screen resolution, the second screen resolution, and the field of view control parameter; and displaying an application interface of the target application based on the determined third screen resolution.

In an embodiment of the present application, the third screen resolution may be obtained based on the first screen resolution, the second screen resolution, and the field control parameter by using a preset parameter calculation formula. For example, the parameter calculation formula is:

third screen resolution=first screen resolution×a+second screen resolution× (1-a);

where A is the value of the vision control parameter.

For example, it is assumed that the first screen resolution is 2400×1920, the second screen resolution is 2400×1080, and the view control parameter value is 0.5, and calculation is performed according to a parameter calculation formula.

And (3) length: 2400×0.5+2400× (1-0.5) =2400;

width: 1920×0.5+1080× (1-0.5) =1500;

The calculated third screen resolution is 2400 x 1500.

Wherein the third screen resolution is less than or equal to the first screen resolution and the third screen resolution is greater than or equal to the second screen resolution.

Fig. 12 is a schematic view of a scenario displaying an application interface according to an embodiment of the present application. As shown in fig. 12, it is assumed that the screen resource resolution of the screen layout resource in the resource file of a target application is 2400×1080, the first screen resolution is 2400×1920, and the second screen resolution is 2400×1080. As shown in fig. 12, when the value of the view control parameter is 1, the third screen resolution is the same as the first screen resolution, that is, the screen layout resource is displayed according to the first screen resolution, the terminal device performs length-width equal-ratio stretching on the screen layout resource based on the short side width of the screen in the first screen resolution, that is, based on 1920, the obtained resolution is 4267×1920, and the ideal display condition corresponding to 4267×1920 is marked as display scene 1. As shown in fig. 12, since the long side of the screen of the display screen of the terminal device is 2400, in this case, there is no side left on the screen, but there are many defects in the display application interface, for example, many areas in the left and right parts of the layout resource of the screen cannot be displayed. As shown in fig. 12, when the value of the view control parameter is 0, the third screen resolution is 2400×1080, which is smaller than the first screen resolution, and the second screen resolution is used to display the screen layout resource, so that the terminal device does not need to stretch the screen layout resource, and marks the ideal display condition corresponding to 2400×1080 as the display scene 2. As shown in fig. 12, in this display case, the screen layout resource can be displayed completely, there is no loss in the display application interface, but there are more edges on the screen. As shown in fig. 12, when the value of the view control parameter is 0.5, the third screen resolution is 2400×1500, and the terminal device performs length-width equal ratio stretching on the screen layout resource with respect to the screen short side width in the third screen resolution, that is, with respect to 1500, to obtain a resolution of 3333×1500, and marks the display situation corresponding to 3333×1500 as the ideal display scene 3. As shown in fig. 12, since the long side of the screen of the terminal device is 2400 only, in this display case, there is a small portion of the screen left, and there is less defect in the display application interface, such as a small portion of the area in the left and right portions of the screen layout resource cannot be displayed.

407, the window manager sends the target screen parameters to the application.

408, the application program constructs an application interface view according to the target screen parameters and the picture layout resources.

409, the application sends the application interface view to the window manager.

The window manager displays the application interface of the application program according to the application interface view 410.

Some embodiments of steps 407-410 may be found in the description above with respect to steps 305-308 of FIG. 5.

According to the application interface display method provided by the embodiment, the third screen resolution is determined based on the first screen resolution, the second screen resolution and the visual field control parameter, and the application interface of the application program is displayed based on the determined third screen resolution; the compromise processing of the display insufficiency and the screen margin is realized through the third screen resolution, namely, compared with the application interface displayed on the basis of the first screen resolution, the application interface displayed on the basis of the third screen resolution can display the information in the picture layout resource more completely, and has fewer defects; meanwhile, the application interface displayed based on the third screen resolution has fewer screen edges than the application interface displayed based on the second screen resolution.

After displaying the application interface of a target application, in order to facilitate the user to adjust the display size of the application interface of the target application, in an embodiment of the present application, after executing step 410, that is, after displaying the application interface of the application program, the method further includes: when the adjustment of the visual field control parameter is detected, the window manager determines a fourth screen resolution based on the adjusted visual field control parameter value and the second screen resolution; and sending the determined fourth screen resolution to the application program, so that the application program reconstructs the application interface view according to the fourth screen resolution and the picture layout resource. And the window manager receives the application interface view sent by the application program and displays the application interface of the application program. In an embodiment of the present application, when the window manager sends the fourth screen resolution to the application program, an interface update instruction is simultaneously sent to the terminal device, so that the application program reconstructs an application interface view according to the fourth screen resolution.

In an embodiment of the present application, the fourth screen resolution may be obtained based on the first screen resolution, the second screen resolution, and the adjusted field control parameter by using a preset calculation formula. For example, the parameter calculation formula is: fourth screen resolution=first screen resolution×b+second screen resolution× (1-B); wherein B is the adjusted view control parameter value. In one embodiment of the present application, after step 410 is performed, i.e. after displaying the application interface of the application program, the method further comprises: and displaying a visual field control push rod on a screen reserved edge beside an application interface of the application program. Some of the foregoing embodiments may be referred to in the related description of fig. 9, and will not be repeated.

According to the embodiment, after the terminal equipment displays the application interface of the target application, the visual field control parameters are monitored, based on the adjustment of the visual field control parameters by the user, the application program is timely controlled to regenerate a new application interface view according to the adjusted fourth screen resolution, the size of the application interface of the currently displayed target application is timely updated, the effect that the application interface is timely adjusted along with the visual field control parameters is achieved, the application interface of the currently displayed target application is more in line with the requirements of the user, and the adjustment efficiency of the application interface is improved.
