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。

此错误发生在用户滚动时适配器中的列表清除，这使得项目holder的位置发生变化，在ui上列表和项目之间失去引用，在next发生错误 “notifyDataSetChanged”请求。

Fix:

检查您的更新列表方法。如果你这样做

mainList.clear();
...
mainList.add() or mainList.addAll()
...
notifyDataSetChanged();

===> Error occur

如何修复。为缓冲区处理创建新的列表对象，然后再次赋值给主列表

List res = new ArrayList();
…..
res.add();  //add item or modify list
….
mainList = res;
notifyDataSetChanged();

感谢Nhan Cao的帮助:)

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

更新RecyclerView到最新的1.2.1版本。奇迹发生了!不能再打破我的应用程序:) 所以. .尝试用gradle文件中的最新版本号替换旧版本号

dependencies {
    ...
    // RecyclerView
    def recyclerview_version = "1.2.1"
    implementation "androidx.recyclerview:recyclerview:$recyclerview_version"
}

Sorry For late but perfect solution: when you try to remove a specific item just call notifydatasetchange() and get these item in bindviewholder and remove that item and add again to the last of list and then chek list position if this is last index then remove item. basically the problem is come when you try to remove item from the center. if you remove item from last index then there have no more recycling and also your adpter count are mantine (this is critical point crash come here) and the crash is solved the code snippet below .

 holder.itemLayout.setVisibility( View.GONE );//to hide temprory it show like you have removed item

        Model current = list.get( position );
        list.remove( current );
        list.add( list.size(), current );//add agine to last index
        if(position==list.size()-1){// remove from last index
             list.remove( position );
        }

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() ; 
 }

}

这是一个相当讨厌的虫子。

为了处理我的项目点击，我使用了RecyclerView的实现。OnItemTouchListener类似于在这个问题中找到的解决方案。

After many times of refreshing the RecyclerView's datasource and clicking an item, this IndexOutOfBoundsException would crash my application. When an item is clicked, the RecyclerView internally goes looking for the correct underlying view and gives back it position. Checking out the source code, I saw that there were some Tasks and Threads scheduled. To cut the story short, basically it's just some illegal state where two datasources are intermixed and not synchronized and the whole thing goes wild.

基于此，我删除了RecyclerView的实现。OnItemTouchListener，并简单地捕捉到适配器自己的ViewHolder上的点击:

public void onBindViewHolder (final BaseContentView holder, final int position) {

    holder.itemView.setOnClickListener(new OnClickListener() {

      @Override
      public void onClick (View view) {

        // do whatever you like here
      }
    });

}

这可能不是最好的解决方案，但目前没有崩溃。希望这将节省你一些时间:)。
