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);
}
