Answer 1

I know that the guy asking the question may have found his own solution but for the people who are still looking for a solution this is a very simple solution but one thing it has a limitation till Kitkat so a condition is added

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

    getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
                      WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
