自从升级到Android支持23.2.0以来,一些开发人员报告了以下堆栈跟踪:

java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.support.v7.widget.RecyclerView$ViewHolder.shouldIgnore()' on a null object reference

当启用RecyclerView的更改动画并且调用相应的RecyclerView.Adapter方法notifyItemInserted(),notifyItemRemoved()等时,会发生这种情况,以指示对适配器管理的列表进行了单独更改(而不是批量更改,由notifyDataSetChanged()指示.

这是由于RecyclerView中的错误,还是我们开发人员做错了什么？
