Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a flowchart illustrating a method for displaying screen contents of a driving recording device according to an embodiment of the present invention, where as shown in fig. 1, the method includes:
step S110, dividing the whole screen into a plurality of screen areas, loading desktop applications on the whole screen, and loading specified applications on the first screen area; the presentation priority of the designated application is better than that of the desktop application.
Fig. 2-a shows a screen presentation effect diagram of the driving recording device. As shown in fig. 2, the left half of the screen is displayed full screen with one interactive application, and the right half is displayed with three card-like widgets and three virtual keys. The desktop application launchers are loaded on the whole screen, the display priority of the map application on the left half screen is higher, and the lower launchers are covered. In fact, the display content of the launcher in this half is blank, i.e. if the display content of the interactive application is hidden at this time, the left half screen will be the background of the launcher. Thus, if the user wishes to slide the screen, there are generally two ways in which this can be selected: firstly, the display of the map application is not processed, if the user slides the screen to the left, the three widgets positioned on the right half screen can be covered by the map application when sliding to the left half screen; twenty the map application is hidden, the user will see the half black screen abruptly as shown in fig. 2-b. This results in a poor user experience. In the present embodiment, the following steps are performed:
step S120, in response to the screen sliding event, acquiring a screenshot of the first screen area.
Step S130, hiding the designated application, and simultaneously displaying the screenshot of the first screen area in the desktop application at a position corresponding to the first screen area.
Step S140, dynamically presenting the desktop application content according to the screen sliding event.
It can be seen that, in the method shown in fig. 1, the whole screen of the driving recording device is divided into a plurality of screen areas, the desktop application is loaded on the whole screen, the designated application with a higher display priority is also loaded on the first screen area, when the screen sliding event input by the user is received, the screen sliding event is triggered by the system, the first screen area is captured and placed in the desktop application, and after the designated application is hidden, the content of the desktop application is displayed on the whole screen, and the captured image of the designated application is displayed in the first screen area, so that the dynamic effect of the desktop application sliding can be normally presented according to the screen sliding event. According to the technical scheme, the multi-screen content can be smoothly displayed synchronously when sliding, the resource occupation is less, the requirement of low power consumption of the driving recording device is met, and meanwhile, the user experience is greatly improved.
In an embodiment of the present invention, in the method, acquiring a screenshot of the first screen area in response to the screen sliding event includes: responding to a screen click event, and performing screenshot on a first screen area and caching; judging whether the screen clicking event is a screen sliding event or not; and if not, deleting the screenshot cache of the first screen area.
Taking the android system as an example, when the device triggers a screen click event, whether the screen click event is a screen sliding event is further judged according to click time, movement amplitude and the like. Specifically, whether the screen click event is a screen sliding event or not can be judged according to an event distribution mechanism. The event distribution mechanism is that in the process of processing an event, if an event is processed by a front processing object, the rear processing object does not perform processing on the event any more, for example, a user clicks a screen, and at this time, the desktop application judges that the user is long-pressing and slides to the left according to the time and the moving amplitude of the click, and even if the user clicks a card-type widget of the application a on the screen, the user cannot continue to trigger opening of the application a. It can be seen that the processing priority of the desktop application is higher, so in this embodiment, when the screen click event is triggered, the screenshot is immediately performed on the first screen area and cached, and if it is determined that the screen click event is not the screen sliding event, the cache is cleared.
In an embodiment of the present invention, the method further includes: setting a widget corresponding to the first screen area in the desktop application at a position corresponding to the first screen area; the step of displaying the screenshot of the first screen area in the position corresponding to the first screen area in the desktop application comprises the following steps: the screenshot of the first screen region is populated into the widget.
In this embodiment, a widget with the same size and the same position as the display area of the designated application in the screen may be set in the launcher, so that after the designated application is hidden, the content of the widget is displayed in the area. The widget is blank in a normal state, and only after the screenshot is carried out on the first screen area, the obtained screenshot is filled into the widget, so that the content of the specified application in the first screen area is hidden, and the display content on the screen is not changed for a user.
In an embodiment of the present invention, in the method, dynamically presenting the desktop application content according to the screen sliding event includes: and processing the desktop application content in the sliding state according to a preset display rule.
In this embodiment, in order to enable the user to obtain a better sliding experience, the desktop content in the sliding state is processed according to a preset display rule, and the following examples are given:
example one:
in this example, dividing the entire screen into a plurality of screen regions includes: setting a second screen area at the center of the whole screen; the preset display rule comprises the following steps: when a central axis of the desktop application content, which is perpendicular to the sliding direction, is located in the second screen area, determining that the display size of the desktop application content is the original size; when a central axis of the desktop application content, which is perpendicular to the sliding direction, is located outside the second screen area, determining the reduction ratio of the desktop application content according to the offset distance of the central axis relative to the central axis of the whole screen in the same direction; and calculating the display size of the desktop application content according to the determined reduction scale and the original size of the desktop application content.
As shown in fig. 2-c, the workplace in the figure represents the visible area of the whole screen; the axis of the widget represents the central axis of the card type widget; pivot is the second screen area. Then the widget axis of the "locomotive guard" application in the figure is outside the pivot, so the card widget of the application is scaled down according to the above rules.
Example two:
in this example, the preset presentation rules include: and when the central axis of the desktop application content, which is perpendicular to the sliding direction, is positioned outside the whole screen, calculating the display size of the desktop application content according to the original size of the desktop application content and the preset minimum scaling.
For example, when a card widget is sliding on the screen or out of the workspace, if the central axis of the widget slides out of or has not yet slid into the workspace, the presentation size of the widget will be reduced to the minimum scaled size.
Example three:
in this example, the preset presentation rules include: if the desktop application content is the content of the designated part in the first screen of the desktop application, when the edge of the desktop application content slides out of the whole screen, the display size of the desktop application content is calculated according to the original size of the desktop application content and the preset minimum scaling.
The first screen of the desktop comprises widgets corresponding to the first screen area and card widgets in the right half screen, wherein when the edge of the card widget in the right half screen slides out of the workplace, the card widget is reduced to the size of the minimum scale.
Example four:
in this example, the preset presentation rules include: if the desktop application content is not the content in the first screen of the desktop application, when the edge of the desktop application content slides out of the whole screen, the display size of the desktop application content is calculated according to the original size of the desktop application content and the preset minimum scaling, and/or when the central axis of the desktop application content, which is perpendicular to the sliding direction, slides out of the whole screen along the specified direction, the display size of the desktop application content is calculated according to the original size of the desktop application content and the preset minimum scaling.
For example, a widget in the left half of the screen, which is not the first screen, is reduced to the minimum-scaled size once its edge slides out of the workspace; once the widget axis of the widget on the right half screen of the non-first screen slides out leftwards, the widget is reduced to the size of the minimum scaling ratio when the widget axis slides out leftwards.
Example five:
in this example, according to a preset presentation rule, processing the desktop application content in the sliding state includes: if the desktop application content is not the screenshot of the first screen area, when a central axis of the desktop application content, which is vertical to the sliding direction, slides through a central axis of the whole screen in the same direction along the specified direction, the desktop application content is faded; and determining the corresponding fading degree according to the offset distance of the central axis of the desktop application content, which is vertical to the sliding direction, relative to the central axis of the whole screen in the same direction.
For example, the degree of fade for the left-most "music" application and the "locomotive guard" application in FIGS. 2-c are treated to different degrees.
In an embodiment of the present invention, the method further includes: after the sliding is stopped, judging whether the current desktop application content contains a screenshot of a first screen area; and if so, displaying the specified application in the first screen area again, and deleting the screenshot in the first screen area from the desktop application content.
For example, after the sliding is stopped, the widget containing the screenshot of the first screen area slides out of the screen, and the content in the launcher is displayed normally; if the widget containing the screenshot of the first screen area is in the screen after the sliding is stopped, the screenshot of the first screen area is deleted from the widget, and the specified application is displayed again, so that the content of the screen seen by the user is still unchanged and is not obtrusive.
