Fullscreen Activity in Android?

Question

How do I make an activity full screen? I mean without the notification bar. Any ideas?

Answer 1

You can do it programatically:

public class ActivityName extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}

Or you can do it via your AndroidManifest.xml file:

Edit:

If you are using AppCompatActivity then you need to add new theme

and then use it.
