and respectively loading the configured view display application through each execution process and simultaneously displaying the view display application on a corresponding screen.
In this embodiment, the system of the electronic device may be an android system, and of course, may also be another type of system. When the system of the electronic equipment is an android system, the number of screens can be acquired from the screen management service when the system of the electronic equipment is started. After the system is started, when an application management core service (ATMS) system receives an instruction of systemweady, a startHomeActivity method can be called to start a program of a screen desktop, and the number of screens and screen identifiers connected with the electronic device can be traversed in the process of starting the program of the screen desktop. And determining the execution process corresponding to the traversed screen identification according to the corresponding relation between the screen identification and the execution process (Action), loading the configured view display application through each execution process, and simultaneously displaying the view display application on the corresponding screen. In general, each Action may be defined in intent. For example, the number of the screens is 3, and the screens are respectively a main screen, a first auxiliary screen and a second auxiliary screen. The corresponding relationship between the screen identifier, the screen desktop and the Action can be shown in the following table 1:
TABLE 1
| Screen | Screen desktop | Action |
| Main screen (Mark 0) | Main screen desktop | CATEGORY_LAUNCHER |
| First auxiliary screen (identification 1) | First sub-screen desktop | CATEGORY_SECONDARY_HOME |
| Second auxiliary screen (identification 2) | Second auxiliary screen table top | CATEGORY_THIRDARY_HOME |
The view display application of the screen desktop can be configured in the Activity XML of the Action corresponding to the view display application, and after configuration, the view display application corresponding to the screen can be determined according to the Action without considering the corresponding relation between the screen and the view display application. The view display applications of each screen desktop are respectively configured to the corresponding actions as shown in table 2 below, where 0, 1, and 2 below the screen desktop in table 2 are screen identifiers corresponding to the screen desktop:
TABLE 2
| Screen desktop | View display application | Activity XML |
| 0 | Home screen view display application | CATEGORY_LAUNCHER |
| 1 | First sub-screen view display application | CATEGORY_SECONDARY_HOME |
| 2 | Second sub-screen view display application | CATEGORY_THIRDARY_HOME |

Specifically, during the system start process of the electronic device, the system starts the SystemUI (the SystemUI is a system-level application). In the system ui starting process, the core services of the status bar and/or the navigation bar can be loaded, and at the same time, systemuugs, which are plug-ins for controlling the status bar and the navigation bar to display, can be loaded through reflection. The system UI can acquire the number of screens from the screen management service when loading the core service of the status bar and/or the navigation bar, traverse the screen identification of the screens, and attach the screen identification of the screens when loading the system UIPlugs through reflection, so that the status bar and/or the navigation bar corresponding to the screen identification can be loaded according to different screen identifications when the system UIPlugs load the views of the status bar and/or the navigation bar. The manner in which each screen id corresponds to each status bar and/or navigation bar, respectively, may be as shown in table 3 below:
TABLE 3
| Screen | SystemUI | SystemUIPlugs |
| 0 | Views of a home screen status bar and/or navigation bar | Status bar and/or navigation bar of home screen |
| 1 | Views of a first secondary screen status bar and/or navigation bar | Status bar and/or navigation bar of first auxiliary screen |
| 2 | Views of a second sub-screen status bar and/or navigation bar | Status bar and/or navigation bar of second sub-screen |
In one embodiment of the invention, the status bar and/or the navigation bar may be customized with corresponding flag bits, respectively; wherein the marker bits may include a display status for displaying the status bar and/or the navigation bar and a hidden status for hiding the status bar and/or the navigation bar;
simultaneously displaying each status bar and/or navigation bar on a screen corresponding to each status bar and/or navigation bar may include:
acquiring the marking bit of each status bar and/or navigation bar;
and simultaneously displaying the status bar and/or the navigation bar marked with the display status on the corresponding screen.
In the embodiment, the mark positions of the status bars and/or the navigation bars are obtained, and the status bars and/or the navigation bars with the mark positions in the display states are simultaneously displayed on the corresponding screens, so that the display or hiding of the status bars and/or the navigation bars on the screens is independently controlled, the adaptation cost is reduced, and finally, the immersive processing of each screen can be realized.
Specifically, for example, the flag bit (flag) of each status bar and/or navigation bar may be customized in the setsystemuivissibility method in view. The status bar and/or the navigation bar may be customized with corresponding flag bits as shown in table 4 below. The mark may be "true" or "false", may also be "1" or "0", and may also be two other different marks, which are not specifically limited herein. For example, if "xxx" of the flag bit is "true", it indicates a display state, and if "false", it indicates a hidden state. In addition to the independent control of the display and hiding of each status bar and/or navigation bar, the properties of background color and transparency of each status bar and/or navigation bar can be independently modified.
TABLE 4
| Screen | Flag bit (Flag) | Status bar and/or navigation bar |
| 0 | View.xxx | Whether or not to display |
| 1 | View.xxx | Whether or not to display |
| 2 | View.xxx | Whether or not to display |
