How to remove a View when animation ends?

I'm creating a game and I would like to display a simple "score"-animation to the player when credits are given to him. This is the view I throw onto the screen:

public class Score extends FrameLayout {

  public Score(Context context, int score) {
    super(context);
    TextView txt = new TextView(context);
    txt.setText(String.valueOf(score).toUpperCase());  
    addView(txt);
    Animation anim = AnimationUtils.loadAnimation(context, R.anim.score);
    startAnimation(anim);
    anim.setAnimationListener(animationListener);
  }
  private void Remove(){

    ViewGroup parent = (ViewGroup)getParent();  
    parent.removeView(this);

  } 
  private AnimationListener animationListener = new AnimationListener() {

    @Override
    public void onAnimationEnd(Animation animation) {

      Remove();
    }  
  };
}

This code actually works pretty well as long as there is only ONE score 开发者_StackOverflow社区animation on screen at any given time. If the player scores again, before the last score was removed, the app crashes - probably because the second score gets the event to remove itself during animation.. Is this a bad practice of using Animation? How would you guys handle this?

I also found that when removing a view from its parent after applying an animation to this view (using onAnimationEnd) crashes with NPE on the dispatchDraw of the parent.

The only solution I found is to trigger the removal inside a post call. Normally all UI modification must be done on the UI thread, so I added a runOnUiThread call on the activity, but it could be useless (it works for me without that).

Animation animation = AnimationUtils.loadAnimation(parentView.getContext(), animationId);
animation.setAnimationListener(new AnimationListener() {
    public void onAnimationStart(Animation paramAnimation) { }
    public void onAnimationRepeat(Animation paramAnimation) { }
    public void onAnimationEnd(Animation paramAnimation) { 
        // without the post method, the main UI crashes if the view is removed 
        parentView.post(new Runnable() {
            public void run() {
                // it works without the runOnUiThread, but all UI updates must 
                // be done on the UI thread
                activity.runOnUiThread(new Runnable() {
                    public void run() {
                        parentView.removeView(view);
                    }
                });
            }
        });
    }
});

view.setVisibility(visibility());
view.startAnimation(animation);

For Kotlin language and using View Binding, this my solution:

      animation.setAnimationListener(object : Animation.AnimationListener {
            override fun onAnimationStart(p0: Animation?) {
            }

            override fun onAnimationEnd(p0: Animation?) {
                mViewBinding
                    .parentViewContainer
                    .post {
                         //The code below will be run on UI thread.
                         mViewBinding
                            .parentViewContainer
                            .removeView(view)
                    }
            }

            override fun onAnimationRepeat(p0: Animation?) {
            }
        })

When using AnimationUtils.loadAnimation view.clearAnimation() solved my problem
