我的方法:
// This snippet hides the system bars.
@SuppressLint("NewApi")
private void hideSystemUI() {
try{
// Set the IMMERSIVE flag.
// Set the content to appear under the system bars so that the content
// doesn't resize when the system bars hide and show.
mDecorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
| View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
| View.SYSTEM_UI_FLAG_IMMERSIVE);
}catch(Exception e){
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
}
// This snippet shows the system bars. It does this by removing all the flags
// except for the ones that make the content appear under the system bars.
@SuppressLint("NewApi")
private void showSystemUI() {
try{
mDecorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}catch(Exception e){
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
mDecorView.setVisibility(View.GONE);
mDecorView.setVisibility(View.VISIBLE);
WindowManager.LayoutParams attrs = getWindow().getAttributes();
attrs.flags |= WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS;
getWindow().setAttributes(attrs);
mDecorView.setPadding(0, getStatusBarHeight(), 0, 0);
}
}

推荐答案
使用View.SYSTEM_UI_FLAG_VISIBLE调用setSystemUiVisibility()会清除所有标志:
Calling setSystemUiVisibility() with View.SYSTEM_UI_FLAG_VISIBLE clears all flags:
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
