How to make an Alert Dialog in full screen in Android?

Answer 1

if you're using DialogFragment to build AlertDialog you may set MATCH_PARENT on LayoutParams in onResume():

@Override
public void onResume() {
    super.onResume();
    ViewGroup.LayoutParams params = getDialog().getWindow().getAttributes();
    params.width = WindowManager.LayoutParams.MATCH_PARENT;
    params.height = WindowManager.LayoutParams.MATCH_PARENT;
    getDialog().getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
}
