アニメーション後のビューを削除する

Question

私はアニメーションを行うビューを持っているので、それを削除したり、少なくともバックに送って再利用することができます。リスナーを付けても問題ありません。

私は約2週間これで立ち往生しているので、どんなヘルプも本当に感謝しています。

私は、カードをスクリーンから飛ばして消してから削除しようとしています。

あなたが川の流れに対して常に泳いでいるように、それは私だけか、Androidアプリを感じさせていますか？

私はonAnimationEndを取り出し、removeAllViewメソッドをその外に置いて動作させました。正直なところ私はこれがどういう仕組みか分かりません。あなたがビューを削除すると、アニメーションの作業ができなくなると思います。

private void flingCardAway(){ 
    View currentAnimCardContainer = findViewById(R.id.card_container); 
    ViewCompat.setTranslationZ(currentAnimCardContainer, 1.0f); 

    AnimationSet anim = new AnimationSet(true); 

    RotateAnimation rotate1 = new RotateAnimation(0,-45, Animation.RELATIVE_TO_SELF,0.5f , Animation.RELATIVE_TO_SELF, 0.5f); 
    rotate1.setStartOffset(1); 
    rotate1.setDuration(400); 
    anim.addAnimation(rotate1); 

    TranslateAnimation trans1 = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, -0.0f, Animation.RELATIVE_TO_PARENT, -1.5f, Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, -0.5f); 
    trans1.setStartOffset(1); 
    trans1.setDuration(550); 
    anim.addAnimation(trans1); 

    AlphaAnimation opacity1 = new AlphaAnimation(1.0f, 0.0f); 
    opacity1.setStartOffset(300); 
    opacity1.setDuration(600); 
    anim.addAnimation(opacity1); 

    currentAnimCardContainer.startAnimation(anim); 

    mCardFrame.removeAllViews(); 

}
