使用RecyclerView过程中遇到异常：

java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder

继承并重写LinearLayoutManager.onLayoutChildren()方法

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).apply { orientation = LinearLayoutManager.VERTICAL }

val recyclerView = view.findViewById<RecyclerView>(R.id.recycler_view).apply {
  layoutManager = manager
  adapter = recyclerAdapter
}
