Description

TECHNICAL FIELD

The present document relates to the technical field of a terminal device with a display screen, and more particularly, to a method and device for controlling switching of a virtual navigation bar.

BACKGROUND OF THE RELATED ART

With the release of Android 4.0, the virtual navigation bar gradually replaces hard keys and becomes the mainstream navigation manner of the mobile phone. This manner solves the problem of excessive wear of the phone keys caused by frequently using the hard keys, and extends the life of the mobile phone. Meanwhile, removing the hard keys of the mobile phone can also save the cost of the mobile phone to a certain extent.

Therefore, the large touch-screen smart phone uses a virtual navigation bar more and more to replace the hard keys, although this manner has some advantages, but dividing the screen into certain areas to simulate the hard key operation will undoubtedly make the using space of the screen smaller, the size of the screen is greatly reduced. Especially for some multimedia applications that require full-screen operations, virtual navigation keys may cause misoperation of the user, which greatly degrades the user experience.

At present, for some third-party software tools, in the case that the system permission is acquired, the virtual navigation bar can be hidden or displayed by modifying the system configuration file and rebooting the mobile phone, but the dynamic switching display control of the display of the virtual navigation bar cannot be performed without rebooting the terminal device. If the existing third-party software tool scheme is used, the user needs to frequently reboot the mobile phone when using, which will reduce the availability of the scheme, for example, in some game scenarios, the user needs to close the virtual navigation bar to play a full-screen game, of course, the user does not want to reboot the mobile phone; likewise, a general user does not know how to crack the system, acquire the system permission, and even modify the system configuration file. Therefore, the feasibility of the existing third-party software scheme is poor in practical use, and the user experience is very poor.
