adapter更新导致的IndexOutOfBoundsExce

1、崩溃日志

 java.lang.IndexOutOfBoundsException:
        at androidx.recyclerview.widget.RecyclerView$Recycler.validateViewHolderForOffsetPosition (RecyclerView.java:5974)

2、原因分析：

  videoFileDataDetailList.clear()
  videoFileDataDetailList.addAll(itemData.videoFileDataList)
  adapterDetail?.notifyItemRangeChanged(0, videoFileDataDetailList.size)

 对该外部数据集做了两个操作：先移除数据，然后添加数据，之后notify数据集。这里，添加数数据时     （Adapter的  内部数据集内容还处在外部数据集移除数据之前），造成了内部和外部数据集不一致

3、解决方法：

      adapter?.notifyDataSetChanged()
