class WrappedLinearLayoutManager : LinearLayoutManager {
constructor(context: Context) : super(context)
constructor(context: Context, orientation: Int, reverseLayout: Boolean) : super(context, orientation, reverseLayout)
constructor(context: Context, attrs: AttributeSet, defStyleAttr: Int, defStyleRes: Int) : super(context, attrs, defStyleAttr, defStyleRes)
override fun onLayoutChildren(recycler: RecyclerView.Recycler?, state: RecyclerView.State) {
try {
super.onLayoutChildren(recycler, state)
} catch (e: IndexOutOfBoundsException) {
e.printStackTrace()
}
}
}
调用时使用WrappedLinearLayoutManager代替LinearLayoutManager

val recyclerAdapter = RecyclerViewAdapter(activity)
val manager = WrapContentLinearLayoutManager(context)
manager.orientation = LinearLayoutManager.VERTICAL
val recyclerView = view.findViewById<RecyclerView>(R.id.recycler_view)
recyclerView.layoutManager = manager
recyclerView.adapter = recyclerAdapter
注：出现这个问题的主要原因，应该是 notifyDataSetChanged 后又调用 notifyItemInserted、notifyItemMoved 等CRUD方法，造成数据的不一致。请仔细检查对数据集操作的事件流是否存在问题。
