当我在recyclerView上调用notifyItemRemoved时，我得到了abstractMethodError

Question

以下是我的错误

java.lang.AbstractMethodError: abstract method "boolean android.support.v7.widget.RecyclerView$ItemAnimator.animatePersistence(android.support.v7.widget.RecyclerView$ViewHolder, 
    android.support.v7.widget.RecyclerView$ItemAnimator$ItemHolderInfo, 
    android.support.v7.widget.RecyclerView$ItemAnimator$ItemHolderInfo)"

Answer 1

调用此方法从recyclerView中删除项目

   public void removeAt(int position, int listSize) {
            list.remove(position);
            notifyItemRemoved(position);
            notifyItemRangeChanged(position, listSize);
        }
