How can you tell if a View is visible on screen in Android?

This code works for me:

public static boolean isVisible(final View view) {
    if (view == null) {
        return false;
    }
    if (!view.isShown()) {
        return false;
    }
    final Rect actualPosition = new Rect();
    view.getGlobalVisibleRect(actualPosition);
    final Rect screen = new Rect(0, 0, getScreenWidth(), getScreenHeight());
    return actualPosition.intersect(screen);
}
