RecyclerView:检测到不一致。无效项位置

我们的QA检测到一个错误:当旋转Android设备(Droid Turbo)时，发生了以下recyclerview相关的崩溃:

java.lang.IndexOutOfBoundsException: 不一致。无效项位置2(偏移量:2).state:3

对我来说，它看起来像一个内部错误在RecyclerView，因为我不能想到这是由我们的代码直接引起的任何方式…

有人遇到过这个问题吗?

解决方案是什么?

一个残酷的解决方法可能是在异常发生时捕获异常并从头重新创建RecyclverView实例，以避免留下损坏的状态。

但是，如果可能的话，我希望更好地理解这个问题(也许从根源上解决它)，而不是掩盖它。

这种细菌不容易繁殖，但一旦发生就会致命。

如果notifyItemChanged(int position)， notifyItemInserted(int position) 当您想要更新项时使用notifyItemChanged，而当您想要添加项时使用notifyItemInserted时，会出现此问题

对我来说，这解决了我的问题

rv.setAdapter(null);
rv.setItemAnimator(null);

PS:我的问题发生时，我做搜索过滤器在我的recyclerview适配器

当你尝试清除你的列表时，这个问题可能会发生，如果你要清除你的数据列表，特别是当你使用拉刷新尝试使用一个布尔标志，初始化它为假，在OnRefresh方法使它为真，清除你的dataList如果标志为真之前添加新的数据到它，之后使它为假。

您的代码可能是这样的

 private boolean pullToRefreshFlag = false ;
 private ArrayList<your object> dataList ;
 private Adapter adapter ;

 public class myClass extend Fragment implements SwipeRefreshLayout.OnRefreshListener{

 private void requestUpdateList() {

     if (pullToRefresh) {
        dataList.clear
        pullToRefreshFlag = false;
     }

     dataList.addAll(your data);
     adapter.notifyDataSetChanged;


 @Override
 OnRefresh() {
 PullToRefreshFlag = true
 reqUpdateList() ; 
 }

}

我通过延迟mrecycle . setadapter (itemsAdapter)解决了这个问题，直到添加了所有的项目到适配器与mrecycle . addall(项目)，它工作。不知道我为什么这么做，这是从一个库的代码，我看了看，看到这些行在“错误的顺序”，我很确定这是它，如果有人能证实它，请解释为什么是这样?甚至不确定这是否是一个有效的答案

One way I managed to fix this (in a Kotlin app with architecture components) was by setting if (recyclerView.adapter == null) recyclerView.adapter = MyAdapter(datasource) after I fetched the data from the Repository. Apparently it might have something to do with async issues with the suspend functions in the repository because when I fetch data for the first time when starting the activity, it calls the REST API since there is no data in the db, and everything goes smoothly, but after that, that same query cannot be made again, causing a crash.

为了解决这个问题，只需在更新循环视图之前调用notifyDataSetChanged()，使用空列表。

例如

//Method for refresh recycle view

    if (!hcpArray.isEmpty())

hcpArray.clear();//更新循环视图列表

adapter.notifyDataSetChanged();
