我们通过log信息查看源码就能明白是什么地方报错了

at android.support.v7.widget.RecyclerView$Recycler.recycleViewHolderInternal(RecyclerView.java:5736)

进入源码查看recycleViewHolderInternal方法

发现是这里报的错。然后Scrapped or attached views may not be recycled. isScrap:false isAttached:true

isAttached:true 表示你的holder.itemView.getParent 不等null 。

所以这时候你就需要去查找你的代码中哪个地方创建了ViewHolder ，在ViewHolder中设置ItemView时是不是设置了parent

我这边是设置了parent, 然后设置了 true， 

解决办法就是 把true 设为false 。或者 把parent设置null。 

以后碰到什么异常多看源码。你能从源码中解决很多问题。
