android - 回転アニメーション後にビューが消えるのはなぜですか?

Question

簡単なゲームを書きました: https://play.google.com/store/apps/details?id=com.ggimer.memorygradladzieci ホイール アイコン - オプションを見てください。// ibtn_menu_opcje これをクリックすると、このアイコンだけが消えるのはなぜですか?

アクティビティ：

private void Opcje() {
    if (!trwa_akcja) {
        if (!pierwsze_nacisniecie){
            pierwsze_nacisniecie = true;
            opcje_layout.setVisibility(View.VISIBLE);
            txt_dziura.startAnimation(rotate_animation);
            ibtn_menu_opcje.startAnimation(rotate_animation);//TODO
            opcje_layout.startAnimation(translate_animation);
        } else {
            txt_dziura.startAnimation(rotate_animation);
            ibtn_menu_opcje.startAnimation(rotate_animation_back);
            opcje_layout.startAnimation(translate_animation_back);
            final Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    pierwsze_nacisniecie = false;
                    trwa_akcja = false;
                    opcje_layout.setVisibility(View.INVISIBLE);
                }
            }, 1000);
        } // if (!pierwsze_nacisniecie)
    } // if(!trwa_akcja) 
} // Opcje()

それを修正する方法は？
