I want to hide the soft key bar (home, back, menu) when a user launches my app. I tried using:

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

But unfortunately as soon as the user interacts with my app, the soft key bar shows again. Is there any way to hide it till the user exits my app?

This is called immersive mode.

check out: https://developer.android.com/training/system-ui/immersive.html

The code that you were asking for is:

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus) {
        getWindow().getDecorView().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
                        | View.SYSTEM_UI_FLAG_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
    }
}

Happy???

  • I had to add this: `getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);` –  May 03 '16 at 12:12
