Fig. 2 shows a flow diagram of a picture display method 200 according to an embodiment of the invention. The method 200 may be performed in a mobile terminal, such as the mobile terminal 100 described above.
As shown in fig. 2, the method 200 begins at step S210. In step S210, in response to the operation of switching to the carousel view presentation page, the carousel view presentation page is displayed.
According to an embodiment of the present invention, an application is installed in the mobile terminal 100, and after the application is opened by a user, the user may switch from a current page to a carousel display page through operations such as clicking, sliding, and the like, and at this time, the carousel display page is displayed in an interface of the mobile terminal 100 in response to the operation of switching to the carousel display page.
Subsequently, step S220 is performed, an instance corresponding to the carousel-chart instance management class is created, and an unused control array is initialized based on the instance, where the unused control array is used for storing an unused picture display control. According to an embodiment of the invention, a class object is generated based on the singleton loading mode in a class creating mode, so that creation of an instance corresponding to the carousel single management class is completed.
When the unused control array is initialized based on the instance, the unused control array may be created based on the instance, the length of the unused control array is initialized to a value corresponding to the preset number, and then the preset number of picture display controls are created and placed in the unused control array.
In this embodiment, one picture display control is used to display one picture, and the preset number is generally set to be the minimum number of pictures that can form a carousel display, for example, the preset number is 2, and then a numerical value corresponding to the preset number is also 2. At this time, the length of the initialized unused control array is 2, and 2 picture display controls are created and put into the unused control array.
According to an embodiment of the invention, the method 200 further comprises: and initializing a used control array based on the instance, wherein the used control array is used for storing used picture display controls. In this embodiment, based on the instance, a used control array is created and initialized to a length of 0. It should be noted that both the unused control arrays and the used control arrays are arrays of linked list structure.
The following are examples of code for creating an instance corresponding to the carousel-chart instance management class, initializing an unused control array and a used control array, and managing the picture display control by the two arrays in the instance, specifically as follows:
the ShareBanner instance is a carousel instance management class, the ImageViewUndesedlist is an unused control array, the ImageViewUsedList is a used control array, and the ImageView is a picture display control.
In step S230, a carousel map component is created, and the use state of the carousel map component is initialized. According to one embodiment of the invention, the carousel map component may be created as follows. In this embodiment, class loading detection is performed first, that is, whether a class corresponding to the carousel view component, such as BannerView, is loaded is checked, and if not, a loading process is performed. Then, a fixed-size memory is allocated to the object corresponding to the class, and the instance field of the class object is initialized to default values such as 0, for example, the use state of the carousel map component, that is, the BannerViewState, may be initialized to default value 0. Then, an object header is set, some information of the object, such as a hash code of the object, is added, a constructor method is executed, a parent class variable, a parent class constructing method, a child class variable and the like are initialized, and accordingly creation of the carousel components and related initialization processing are completed.
Finally, step S240 is executed, if the number of the picture display controls in the unused control array is not less than the preset number, the preset number of the picture display controls are taken out from the unused control array and added to the carousel image assembly, so as to perform circular picture scrolling display on the carousel image display page.
According to an embodiment of the invention, if the number of the picture display controls in the unused control array is not less than 2, 2 picture display controls are taken out from the unused control array and added into the carousel image component, so that the pictures are displayed on the carousel image display page in a circular rolling manner. The carousel view component Banner View is a component capable of circularly displaying pictures, and mainly sends messages at regular time through a message notification mode to notify a picture display control to carry out picture rolling display, so that values taken from unused control arrays are directly assigned to objects corresponding to 2 picture display controls in the carousel view component actually. And 1 picture display control in the 2 picture display controls is used for displaying the currently displayed picture, and the other 1 picture display control is used for displaying the next picture to be displayed in a rolling way, so that the corresponding picture can be displayed through the picture display control in the carousel display.
According to an embodiment of the invention, the method 200 further comprises: and if the number of the picture display controls in the unused control array is smaller than the preset number, subtracting the number of the picture display controls in the unused control array from the preset number to obtain a number difference value, and creating a number difference value picture display control to be placed in the unused control array.
In this embodiment, if the number of the picture display controls in the unused control array is less than 2, for example, the number of the picture display controls in the unused control array is 1, calculating 2-1 to obtain a number difference value of 1, and creating 1 picture display control and placing the picture display control into the unused control array.
When a user views the carousel map display page, various possible operations of the user can have corresponding influences on the state of the carousel map component. For example, when a user normally views the carousel map display page, the carousel map component is in a display state at this time, the user operates the current application to return to the background, lock the screen, open a new page to cover the original carousel map display page, and the like, so that the carousel map component is in a hidden state, and when the current carousel map display page is returned and the system recovers the page, the carousel map component is in a destroyed state. For different states of the carousel map component, the current state of the carousel map component can be reflected by setting a corresponding value for the use state.
In view of the above, according to yet another embodiment of the present invention, the method 200 further comprises: and acquiring the use state of the carousel image assembly, judging whether a new carousel image assembly needs to be created, if so, creating the new carousel image assembly, and initializing the use state of the new carousel image assembly. Thereafter, the picture presentation can continue through the new carousel picture component.
According to yet another embodiment of the invention, the method 200 further comprises: if the use state meets the first preset condition, determining that the carousel graph assembly is in a destruction state, removing all the in-use picture display controls from the carousel graph assembly, and synchronously removing all the removed in-use picture display controls from the used control array.
In this embodiment, the first preset condition is that the value of the usage status is 2, that is, bannerViewState =2, indicating that the carousel component is in the destruction state, at this time, the 2 picture display controls in use are removed from the carousel component, and the 2 picture display controls are removed from the used control array synchronously.
According to yet another embodiment of the invention, the method 200 further comprises: and if the using state meets a second preset condition, determining that the carousel image assembly is in a hidden state, releasing the non-displayed picture display control from the carousel image assembly, synchronously removing the released non-displayed picture display control from the used control array, and putting the released non-displayed picture display control into the unused control array.
In this embodiment, the second preset condition is that the value of the usage state is 1, that is, banner viewstate =1, indicating that the carousel component is in a hidden state, the non-illustrated 1 picture display control is released from the carousel component, and the picture display control is synchronously removed from the used control array and placed into the unused control array.
According to yet another embodiment of the invention, the method 200 further comprises: and if the use state meets a third preset condition, determining that the carousel image assembly is in the display state, acquiring the use state of the carousel image assembly again, and judging whether a new carousel image assembly needs to be created.
In this embodiment, the third preset condition is that the value of the use state is 0, i.e., bannerViewState =0, indicating that the carousel component is in the display state. It should be noted that, when determining whether the usage status satisfies the first preset condition, the second preset condition, and the third preset condition, it may be directly determined which preset condition the usage status satisfies by the value of the usage status, or it may be determined whether the usage status satisfies the first preset condition, and when the usage status satisfies the first preset condition, corresponding processing is executed, and when the usage status does not satisfy the first preset condition, it is determined whether the usage status satisfies the second preset condition. When the using state meets the second preset condition, corresponding operation is carried out, and when the using state also does not meet the second preset condition, the using state can be directly determined to meet the third preset condition, and at the moment, corresponding processing is executed.
Fig. 3 shows a schematic diagram of a picture display module 300 according to an embodiment of the invention. The picture display module 300 resides in a mobile terminal (e.g., the aforementioned mobile terminal 100). The picture display module 300 circularly scrolls and displays pictures by performing the picture display method 200 of the present invention.

The page display unit 310 may display the carousel presentation page in response to a switch operation to the carousel presentation page. The first creating unit 320 may create an instance corresponding to the carousel map instance management class, and initialize an unused control array based on the instance, where the unused control array is used to store an unused picture display control. The second creating unit 330 may create a carousel map component, and initialize a use state of the carousel map component. The picture display unit 340 may take out a preset number of picture display controls from the unused control array and add the picture display controls to the carousel map component when the number of the picture display controls in the unused control array is not less than the preset number, so as to perform circular picture scrolling display on the carousel map display page.
