this may help you...

public ArrayList<Button> getButtons() {
    ArrayList<Button> buttons = new ArrayList<Button>();
    ViewGroup viewGroup = (ViewGroup) getWindow().getDecorView();
    findButtons(viewGroup, buttons);
    return buttons;
}

private static void findButtons(ViewGroup viewGroup,ArrayList<Button> buttons) {
    for (int i = 0, N = viewGroup.getChildCount(); i < N; i++) {
        View child = viewGroup.getChildAt(i);
        if (child instanceof ViewGroup) {
            findButtons((ViewGroup) child, buttons);
        } else if (child instanceof Button) {
            buttons.add((Button) child);
        }
    }
}
