Как поменять иконку в раздутом меню

Question

Привет и спасибо за вашу помощь.

У меня проблема с изменением иконки в раздутом меню. Я могу успешно изменить значок при условии, что я использую onOptionsItemSelected. Если я попытаюсь сделать это откуда-то еще, это не будет сделано. Что я делаю не так? Спасибо за вашу помощь.

    test() {
                if (dbHandler.play == false) {
                    //the line below wouldn't work
                    menu.getItem(1).setIcon(ContextCompat.getDrawable(this, R.drawable.ic_play_arrow_black_24dp));
                }
    }

    @Override
    public boolean onOptionsItemSelected(@NonNull MenuItem item) {
        switch (item.getItemId()) {
            case R.id.play:
                if (dbHandler.play == true) {
                    menu.getItem(1).setIcon(ContextCompat.getDrawable(this, R.drawable.ic_play_arrow_black_24dp));
                } else {
                    menu.getItem(1).setIcon(ContextCompat.getDrawable(this, R.drawable.ic_stop_black_24dp));
                }

                return true;

            default:
                return super.onOptionsItemSelected(item);
        }
    }
