这是RecyclerView的报错。数据列表与recyclerView的view holder不一致导致报错。 比如有代码： list.clear(); ... list.addAll(newList) 解决方法1： int size = list.size(); ... list.clear(); adapter.notifyItemRangeRemoved(0, size); ... list.addAll(newList) adpater.notifyitemRangeChanged(0, list.size())

也可以使用一个adpater.notifyDataSetChanged(); 但是这个不被推荐。 解决方法2: 捕获异常 public class LinearLayoutManagerWrapper extends LinearLayoutManager { @Override public void onLayoutChildren(RecyclerView recycler, RecyclerView.State state) { try { super.onLayoutChildren(recycler, state) } catch (IndexOutOfBoundsException e) { // do something... } } } 使用该LinearLayoutMangerWrapper的包装类 rv.layoutManager = LinearLayoutManagerWrapper(this);
