Android has introduced a lot of different API for controlling system UI visibility throughout its evolution. In order to simplify such complexity, SystemUiHelper categorized the possible behavior into LEVEL_LOW_PROFILE, LEVEL_HIDE_STATUS_BAR, LEVEL_LEAN_BACK and LEVEL_IMMERSIVE. Each one is pretty self explanatory.
Although there have been some other projects available, I created this library because this way I can always try to track the latest upstream changes. Third-party fixes are also welcomed to be incorporated.
This library has already included a fix for delayed system UI visibility change from myself.
What's more, a sample application is given on how to use the SystemUiHelper with Toolbar from appcompat-v7.
Gradle:
compile 'me.zhanghai.android.systemuihelper:library:1.0.0'In Activity.onCreate():
mSystemUiHelper = new SystemUiHelper(this, SystemUiHelper.LEVEL_IMMERSIVE,
SystemUiHelper.FLAG_IMMERSIVE_STICKY,
new SystemUiHelper.OnVisibilityChangeListener() {
@Override
public void onVisibilityChange(boolean visible) {
...
}
});
// This will set up window flags.
mSystemUiHelper.show();You can refer to the sample app's MainActivity for detail.
