Was ist los? Ich kann seit Tagen nicht lösen.

Answer 1

refering zu this, können Sie versuchen, dass:

case DragEvent.ACTION_DROP: 
    final View droppedView = (View) event.getLocalState(); 
    ViewGroup owner = (ViewGroup) droppedView.getParent(); 
    owner.post(new Runnable(){ 
     @Override 
     public void run() { 
      owner.removeView(droppedView); 
     } 
    }); 
}
