Video player lights out mode in Android using appcompat-v7

I’ve found fitssystemwindows pretty unreliable as well when you want some elements of the view hierarchy to be fullscreen and some elements to be below the status bar or action bar. But I’ve never seen the action bar behind the status bar. Is the Toolbar set as the activity actionbar? Are you using Window.FEATURE_ACTION_BAR_OVERLAY? Anyway, if all you need is to get a number of pixels for the paddingTop in onResume(), it might be a bit cleaner (still hacky though) to do something like the following rather than use OnPreDrawListeners.

class MyVideoActivity extends Activity {
    Toolbar bar;

    //...

    @Override protected void onResume() {
        super.onResume();
        bar.setPaddingTop(getStatusBarHeight());
    }

    int getStatusBarHeight() {
        int result = 0;
        Resources res = getResources();
        int resourceId = res.getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 0) {
            result = res.getDimensionPixelSize(resourceId);
        }
        return result;
    }
}
