It should be noted that the method provided in the embodiments of the present application is not limited to the specific order described in FIG. 2 and the following. The specific process of the method is as follows:

步骤S210，对接收的按键事件进行检测。Step S210, detecting the received key event.

其中，按键事件表征用户通过按动遥控设备上的控制键以控制智能电视100的显示单元150执行相应的显示任务。本实施例中，按键事件可以为用户通过按动遥控设备上的控制键来控制智能电视100的显示单元150执行视图滚动。Wherein, the button event indicates that the user controls the display unit 150 of the smart television 100 to perform a corresponding display task by pressing a control button on the remote control device. In this embodiment, the button event may be that the user controls the display unit 150 of the smart TV 100 to perform view scrolling by pressing a control button on the remote control device.

本实施例中，作为一种实施方式，请参阅图3，所述步骤S210可以包括以下子步骤：In this embodiment, as an implementation manner, referring to FIG. 3, the step S210 may include the following sub-steps:

子步骤S211，获取按键事件对应的按键时长。Sub-step S211, obtaining the button duration corresponding to the button event.

其中，本实施例中，按键时长表征用户按动遥控设备上的控制键的时长。应当理解，按键时长可以为用户按动遥控设备的控制键直至松开控制键之间所耗费的时间。根据不同 的按键时长，可以设置不同的显示任务，例如视图的滚动。In this embodiment, the duration of the button indicates the duration of the user pressing the control button on the remote control device. It should be understood that the duration of the button may be the time it takes for the user to press the control button of the remote control device until the control button is released. According to different The duration of the button can be set to different display tasks, such as the scrolling of the view.

子步骤S212，将所述按键事件对应的按键时长与预设时长阈值进行比对。Sub-step S212, comparing the button duration corresponding to the button event with a preset duration threshold.

本实施例中，在接收到遥控设备发送的按键事件(KeyEvent)时，将所述按键事件对应的按键时长与预设时长阈值进行比对。其中，所述预设时长阈值可以根据设计需求进行设置，本实施例对此不作具体限制。作为一种可选的实施方式，所述预设时长阈值可以设置为120ms。In this embodiment, when a key event (KeyEvent) sent by the remote control device is received, the button duration corresponding to the button event is compared with a preset duration threshold. The preset duration threshold may be set according to the design requirement, which is not specifically limited in this embodiment. As an optional implementation manner, the preset duration threshold may be set to 120 ms.

子步骤S213，根据比对结果判断所述按键事件是否为长按键事件。Sub-step S213, determining whether the button event is a long button event according to the comparison result.

本实施例中，若所述按键事件对应的按键时长大于所述预设时长阈值，则判定所述按键事件为长按键事件。In this embodiment, if the button duration corresponding to the button event is greater than the preset duration threshold, it is determined that the button event is a long button event.

步骤S220，在检测到所述按键事件为长按键事件时，控制视图滚动所述视图滚动步数对应的视图距离。Step S220, when it is detected that the button event is a long button event, the control view scrolls the view distance corresponding to the number of view scroll steps.

现有的智能电视的视图的加载都由按键进行控制，由于绝大多数智能电视没有屏幕压力传感器，且人与智能电视之间通过遥控设备进行意图传输，因此智能电视与人之间无法进行直接交互，从而导致的一个问题是，当用户按下按键(例如，向下按键)，假设视图滚动20个单位距离(像素密度PPI)；如果用户长按向下按键一秒，按照手指按遥控按键的最快频率为20ms，那么1s内会触发50次按键，因此1s理想滚动距离为50*20＝1000个单位距离，但经申请人实际测试发现视图快速滚动了至少6000个单位距离，远远超过理想滚动距离。The loading of the existing smart TV view is controlled by the button. Since most smart TVs do not have a screen pressure sensor, and the intentional transmission between the person and the smart TV through the remote control device is impossible, the smart TV and the person cannot directly One problem caused by interaction is that when the user presses a button (for example, down button), the view is assumed to scroll by 20 unit distances (pixel density PPI); if the user presses the down button for one second, press the remote button according to the finger. The fastest frequency is 20ms, then 50 keys will be triggered within 1s, so the ideal rolling distance of 1s is 50*20=1000 unit distance, but the actual test shows that the view has quickly scrolled at least 6000 unit distances. Exceed the ideal rolling distance.

上述按键模式中，长按1秒导致滑动距离远远超过理想距离值，经发明人研究发现根本原因在于按键指令在分发消费的过程中是以一种队列进行先进先出的处理，而长按按键将导致按键事件大批量地进入按键队列，从而导致在极短的时间内按键事件队列出现阻塞，而阻塞的后果就是View无法获取按键事件结束指令(KeyUp)，进而导致视图出现无限滑动，视图容器控件顶部或底部容易出现空白，尤其是在某些情况(例如，高清大图的视图加载过程中)，长按按键很容易出现应用程序无响应(Application Not Responsed，ANR)异常或内存溢出(Out Of Memery，OOM)异常。In the above button mode, long press for 1 second causes the sliding distance to far exceed the ideal distance value. The inventor's research found that the root cause is that the button command is a queue for FIFO processing in the process of distribution and consumption, and long press The button will cause the button event to enter the button queue in large quantities, resulting in blocking of the button event queue in a very short time. The result of blocking is that the View cannot obtain the key event end command (KeyUp), which causes the view to slide infinitely. It is easy to appear blank at the top or bottom of the container control, especially in some cases (for example, during the view loading of high-definition large images), long-pressing the button is prone to Application Unscheduled (ANR) exception or memory overflow ( Out Of Memery, OOM) is abnormal.

而本实施例可以完美解决上述长按键事件带来的视图过度加载的问题。在本实施例中，所述智能电视100预先配置有短按键事件对应的单位滚动距离值，以及长按键事件对应的视图滚动步数。其中，所述短按键事件由将所述按键事件对应的按键时长与预设时长阈值进行比对，并根据比对结果判断得到。例如，若所述按键事件对应的按键时长小于所述预设时长阈值，则判定所述按键事件为短按键事件。另外，所述单位滚动距离值对应视图滚动一步的距离值。The embodiment can perfectly solve the problem of excessive loading of the view caused by the long button event. In this embodiment, the smart TV 100 is pre-configured with a unit scroll distance value corresponding to a short button event and a view scroll step corresponding to the long button event. The short button event is compared with a preset duration threshold by the button duration corresponding to the button event, and is determined according to the comparison result. For example, if the button duration corresponding to the button event is less than the preset duration threshold, it is determined that the button event is a short button event. In addition, the unit scroll distance value corresponds to a distance value in which the view scrolls one step.

进一步地，本实施例可以对所述单位滚动距离值进行设置。本实施例中，对所述单位 滚动距离值进行设置的步骤可以包括：Further, the embodiment may set the unit scroll distance value. In this embodiment, the unit is The steps of setting the scroll distance value may include:

计算所述智能电视100的显示屏幕的像素密度的最大近似值。A maximum approximation of the pixel density of the display screen of the smart television 100 is calculated.

根据所述智能电视100的单位像素长度和像素密度的最大近似值计算所述单位滚动距离值。The unit scroll distance value is calculated based on a maximum approximation of the unit pixel length and the pixel density of the smart TV 100.

本实施例中，所述单位滚动距离值的计算公式可以为：In this embodiment, the calculation formula of the unit rolling distance value may be:

其中，USV为单位滚动距离值，PPIMAX为像素密度最大近似值，HPX为单位像素长度，Px为分辨率横向取值、Py为分辨率纵向取值，C为显示屏幕对角线长度。Among them, USV is the unit rolling distance value, PPIMAX is the maximum approximation of pixel density, HPX is the unit pixel length, Px is the resolution horizontal value, Py is the resolution vertical value, and C is the display screen diagonal length.

在一般情况下，所述像素密度为默认值，例如，以47英寸，1920*1080分辨率的智能电视100为例，其像素密度为320，单位像素长度为2.559，根据上述计算式可以计算出所述USV＝320*2.55＝818.97英寸，因此每按下一次向下按键(KeyDown)，那么视图就向上滚动818.97英寸的距离。但是由于电视市场的杂乱无章，导致部分电视的像素密度并非标准的像素密度取值。In general, the pixel density is a default value. For example, a smart TV 100 with a resolution of 47 inches and 1920*1080 is taken as an example. The pixel density is 320, and the unit pixel length is 2.559. According to the above calculation formula, the calculation can be calculated. The USV=320*2.55=818.97 inches, so each time the down button (KeyDown) is pressed, the view scrolls up by 818.97 inches. However, due to the disorder of the TV market, the pixel density of some TVs is not the standard pixel density.

鉴于此，本实施例还可以解决部分电视的显示屏幕每英寸所拥有的像素数目(Pixels Per Inch，PPI)为非标准值的问题。作为一种实施方式，本实施例可以通过计算像素密度的最大近似值来解决非标准像素密度的智能电视100的单位滚动距离值计算问题，从而覆盖兼容目前所有的智能电视100。In view of this, the embodiment can also solve the problem that the number of pixels (Pixels Per Inch, PPI) per inch of the display screen of some televisions is a non-standard value. As an embodiment, the present embodiment can solve the problem of calculating the unit scroll distance value of the non-standard pixel density smart television 100 by calculating the maximum approximation of the pixel density, thereby covering all smart TVs 100 compatible.

本实施例中，所述计算像素密度的最大近似值的步骤可以包括：In this embodiment, the step of calculating a maximum approximation of the pixel density may include:

建立ldpi-xxhdpi的分辨率离散点集，其中，所述离散点集集合可以为:{[240,320],[320,480],[480,800],[720,1280],[1080,1920]}。A resolution discrete point set of ldpi-xxhdpi is established, wherein the discrete point set set can be: {[240, 320], [320, 480], [480, 800], [720, 1280], [1080, 1920]}.

对ldpi-xxhdpi的分辨率离散点集进行拟合，得到拟合后的ldpi-xxhdpi分布曲线。The ldpi-xxhdpi resolution point set is fitted to obtain the fitted ldpi-xxhdpi distribution curve.

根据上述拟合后的ldpi-xxhdpi分布曲线，将像素密度标记在拟合后的ldpi-xxhdpi分布曲线的坐标上。Based on the above-described fitted ldpi-xxhdpi distribution curve, the pixel density is marked on the coordinates of the fitted ldpi-xxhdpi distribution curve.

求取像素密度在拟合后的ldpi-xxhdpi分布曲线的点坐标与ldpi-xxhdpi分布曲线的垂直焦点。The pixel focus is obtained from the point coordinates of the fitted ldpi-xxhdpi distribution curve and the vertical focus of the ldpi-xxhdpi distribution curve.

根据所述垂直焦点得到所述像素密度的最大近似值。A maximum approximation of the pixel density is obtained from the vertical focus.

进一步地，本实施例中还可以对所述视图滚动步数进行设置。所述对所述视图滚动步数进行设置可以包括：Further, in the embodiment, the number of scrolling steps of the view may also be set. The setting the number of scrolling steps of the view may include:

计算视图滚动的初始距离值。Calculates the initial distance value for the view scroll.

根据所述初始距离值和预设的单位滚动距离值，计算所述视图滚动步数。 The number of view scroll steps is calculated according to the initial distance value and a preset unit scroll distance value.

本实施例中，所述视图滚动步数的计算公式为：In this embodiment, the calculation formula of the number of scroll steps of the view is:

其中，VH为视图滚动的初始距离值，USV为预设的单位滚动距离值。Among them, VH is the initial distance value of the view scroll, and USV is the preset unit scroll distance value.

以47英寸，1920*1080分辨率的智能电视100为例，屏幕高度方向最大可显示1080像素的视图，在上下滚动高度为1920像素时，单位滚动距离值USV＝818.97<1080，因此USV计算合理，则所述视图滚动步数SP的计算公式为：Take the 47-inch, 1920*1080 resolution smart TV 100 as an example. The screen height direction can display up to 1080 pixels. When the scroll height is 1920 pixels, the unit scroll distance value is USV=818.97<1080, so the USV calculation is reasonable. , the calculation formula of the view scroll step SP is:

计算SP＝1920/818.97≈3，其中VH为视图的初始距离值。那么所述视图滚动步数则为三步。Calculate SP=1920/818.97≈3, where VH is the initial distance value of the view. Then the number of view scroll steps is three steps.

本实施例中，所述初始距离值可以包括初始高度值或者初始宽度值。若视图进行上下滚动，则所述初始距离值为初始高度值，若视图进行左右滚动，则所述初始距离值为初始宽度值。In this embodiment, the initial distance value may include an initial height value or an initial width value. If the view is scrolled up and down, the initial distance value is an initial height value, and if the view is scrolled left and right, the initial distance value is an initial width value.

可选地，以所述初始距离值为初始高度值为例，所述视图滚动的初始距离值的计算方式可以包括：Optionally, the initial distance value is an initial height value, and the initial distance value of the view scroll may be calculated by:

对图片载体控件(ImageView)进行检测。The image carrier control (ImageView) is detected.

若所述图片载体控件处于创建阶段，则调用getHeigth函数获取所述图片载体控件的第一高度值。If the picture carrier control is in the creation phase, the getHeigth function is called to obtain the first height value of the picture carrier control.

判断所述第一高度值是否大于0，若大于0，则将所述第一高度值作为所述视图滚动的初始高度值。Determining whether the first height value is greater than 0, and if greater than 0, using the first height value as an initial height value for scrolling the view.

若所述图片载体控件创建完成并被容纳入滚动控件，也就是视图滚动之前的阶段，此时则调用getMeasureHeight函数获取所述图片载体控件的第二高度值。If the picture carrier control is created and is accommodated in the scroll control, that is, the stage before the view scrolling, then the getMeasureHeight function is called to obtain the second height value of the picture carrier control.

判断所述第二高度值是否大于所述第一高度值，若大于所述第一高度值，则将所述第二高度值作为所述视图滚动的初始高度值；若不大于所述第一高度值，则将所述第一高度值作为所述视图滚动的初始高度值。Determining whether the second height value is greater than the first height value, and if greater than the first height value, using the second height value as an initial height value of the view scroll; if not greater than the first The height value is used as the initial height value for scrolling the view.

本实施例中，在检测到所述按键时间为长按键事件时，可以根据上述设置的单位滚动距离值和视图滚动步数，控制视图对应进行滚动。本实施例中，请参阅图4，所述步骤S220可以包括以下子步骤：In this embodiment, when it is detected that the button time is a long button event, the control view may be scrolled according to the set unit scroll distance value and the view scroll step number. In this embodiment, referring to FIG. 4, the step S220 may include the following sub-steps:

子步骤S221，解析所述按键事件对应的按键事件指令。Sub-step S221, parsing the key event instruction corresponding to the button event.

本实施例中，可以将遥控设备发送的按键事件转化为对应的按键事件指令。其中，所述按键事件可以包括上方向按键、下方向按键、左方向按键、右方向按键、确定按键以及返回按键。所述按键事件与按键事件指令的对应关系可以参阅下表。 In this embodiment, the key event sent by the remote control device can be converted into a corresponding key event instruction. The button event may include an up direction button, a down direction button, a left direction button, a right direction button, a determine button, and a return button. The correspondence between the button event and the button event command can be referred to the following table.

子步骤S222，响应所述按键事件指令，控制视图滚动所述视图滚动步数对应的视图距离。Sub-step S222, in response to the button event instruction, the control view scrolls the view distance corresponding to the number of view scroll steps.

本实施例中，在解析得到所述按键事件对应的按键事件指令后，响应所述按键事件指令，按照所述按键事件指令的对应方向控制视图滚动所述视图滚动步数对应的视图距离。例如，若所述按键事件指令为FOCUS_DOWN，那么就控制所述视图向上滑动所述视图滚动步数对应的视图距离。若所述按键事件指令为FOCUS_UP，那么就控制所述视图向下滑动所述视图滚动步数对应的视图距离。若所述按键事件指令为FOCUS_LEFT，那么就控制所述视图向右滑动所述视图滚动步数对应的视图距离。若所述按键事件指令为FOCUS_RIGHT，那么就控制所述视图向左滑动所述视图滚动步数对应的视图距离。若所述按键事件指令为FOCUS_FORWORD，那么就控制所述视图停止滑动。若所述按键事件指令为FOCUS_BACKWORD，那么就控制所述视图切换至前一目录的视图。In this embodiment, after the button event command corresponding to the button event is parsed, in response to the button event command, the view distance corresponding to the view scroll step is scrolled according to the corresponding direction control view of the button event command. For example, if the button event command is FOCUS_DOWN, then the view is controlled to slide up the view distance corresponding to the number of view scroll steps. If the button event command is FOCUS_UP, then the view is controlled to slide down the view distance corresponding to the view scrolling step number. If the button event instruction is FOCUS_LEFT, then the view is controlled to slide the view distance corresponding to the number of steps of the view to the right. If the button event command is FOCUS_RIGHT, then the view is controlled to slide the view distance corresponding to the number of view scroll steps to the left. If the button event command is FOCUS_FORWORD, then the view is controlled to stop sliding. If the button event command is FOCUS_BACKWORD, then the view is controlled to switch to the view of the previous directory.

需要注意的是，视图在滚动过程中一旦出现重绘，那么其初始长度值会发生变化，因此计算的单位滚动距离值USV会失效。为了防止视图重绘导致的单位滚动距离值计算失效的问题，请参阅图5，所述步骤S220还可以包括以下子步骤：It should be noted that once the view is redrawn during the scrolling process, its initial length value will change, so the calculated unit scroll distance value USV will be invalid. In order to prevent the problem that the unit scroll distance value calculation fails due to view redrawing, please refer to FIG. 5, and the step S220 may further include the following sub-steps:

子步骤S223，调用滚动监控器对视图的滚动过程进行监控。Sub-step S223, the scroll monitor is called to monitor the scrolling process of the view.

子步骤S224，若在视图的滚动过程中接收到重绘视图指令，则在所述视图滚动结束后处理所述重绘视图指令对应的重绘事件。Sub-step S224, if a redraw view instruction is received during the scrolling of the view, the redraw event corresponding to the redraw view instruction is processed after the view scroll ends.

本实施例中，可以通过调用滚动监控器(ScrollListener)来监控所述视图的滚动，并检测滚动过程中是否接收到重绘视图指令。若检测到滚动过程中接收到重绘视图指令，则延迟对重绘事件进行处理，直到所述滚动监控器(ScrollListener)监控到所述视图滚动结束后，开始处理所述重绘视图指令对应的重绘事件。In this embodiment, the scrolling of the view can be monitored by calling a scroll monitor (ScrollListener), and detecting whether a redraw view instruction is received during scrolling. If it is detected that the redrawing view instruction is received during the scrolling process, delaying the redrawing event processing, until the scrolling monitor (ScrollListener) monitors that the scrolling of the view ends, processing the processing corresponding to the redrawing view instruction Redraw the event.

请再次参阅图2，步骤S230，在所述视图滚动完所述视图滚动步数对应的视图距离时，显示滚动后的视图。Referring to FIG. 2 again, in step S230, when the view scrolls the view distance corresponding to the number of scroll steps of the view, the scrolled view is displayed.

本实施例中，在所述视图滚动完所述视图滚动步数对应的视图距离后，所述视图完成最大滚动距离，即使用户继续长按按键，视图不再继续滚动，从而解决了现有的长按键事件带来的视图过度加载的问题。In this embodiment, after the view scrolls the view distance corresponding to the number of scroll steps of the view, the view completes the maximum scroll distance, and even if the user continues to press the button, the view does not continue to scroll, thereby solving the existing The problem of over-loading the view caused by long button events.

值得注意的是，在其它实施方式中，所述单位滚动距离值和所述视图滚动步数也可以 不仅限于本实施例提供的计算方式，例如，还可以由用户直接进行设置，或者由电视厂商进行设置。此外，还需要注意的是，本实施例提供的方法也可以不仅限于应用于智能电视100，还可以应用于智能机顶盒、电视机盒子等设备上。It should be noted that in other embodiments, the unit scroll distance value and the view scroll step number may also be It is not limited to the calculation method provided by this embodiment, for example, it can also be set directly by the user or set by the TV manufacturer.
