Implementation method: Add a custom service in the frameworks, receive the upper-layer application broadcast, and then send the function of controlling display and hiding through this service, or the upper-layer application can send a broadcast to directly control the display and hiding, because there are other functions, so add it separately Made a service

Instructions for displaying and hiding the status bar
If you only use mStatusBarView.setVisibility(View.GONE);to hide and use mStatusBarView.setVisibility(View.VISIBLE);to display, all the content in the status bar is hidden when hiding, but the height of the status bar is still there, and it still takes up space. The upper application needs to be set to full screen display In order to completely hide the position of the status bar, that is to add in the upper application
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN);
This modification does not have the risk of systemui exceptions.
However, some customers request to display the navigation bar but hide the status bar. This method cannot be used at this time. When hiding, the status bar needs to be completely removed. When using this method, several places need to be modified, otherwise systemui will be abnormal.
When using the completely hidden method, you need to modify
it. Modify:frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/HeadsUpManagerPhone.java
