Toolbar with Immersive Full-Screen Mode

android, android-actionbar, android-toolbar

Solution

Try this

 @Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
        if (hasFocus) {
            getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
        }
    }
}

Problem

Is it possible to use `Immersive Mode` on Android KitKat and Lollipop in combination with a Toolbar? Toolbar ``` <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="?attr/colorPrimary" android:minHeight="?attr/actionBarSize" app:popupTheme="@style/ThemeOverlay.AppCompat.Light" app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" /> ``` hide Action Bar (Toolbar) ``` // This snippet hides the system bars. // https://developer.android.com/training/system-ui/immersive.html private void hideSystemUI() { // 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. 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 // hide nav bar | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar | View.SYSTEM_UI_FLAG_IMMERSIVE); getSupportActionBar().hide(); } ``` This works fine. But the Toolbar doesn't appear again.
