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。

当前回答

我也遇到过类似的问题，只是想办法解决了。我为一个测试用例硬编码了一些示例，但没有确保它们每个都返回唯一的ID，这导致了下面的崩溃。修复id解决了这个问题，希望这能帮助到其他人!

其他回答

这是唯一的解决方案，对我来说，即使尝试了许多以上的解决方案。

1)。Intilization

CustomAdapter scrollStockAdapter = 
         new CustomAdapter(mActivity, new ArrayList<StockListModel>());
list.setAdapter(scrollStockAdapter);
scrollStockAdapter.updateList(stockListModels);

2)。在适配器中编写此方法

public void updateList(List<StockListModel> list) {
    stockListModels.clear();
    stockListModels.addAll(list);
    notifyDataSetChanged();
}

stockListModels ->这个列表是你在适配器中使用的。

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:)

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 );
        }

Most of the answers are disabling animations or creating new copies of data which is an overkill in my opinion. They do work but they don't address the root cause of the issue. In my case it was due to using DiffUtils in a wrong way. In the areItemsTheSame(old, new) method I did not properly implement the equality check, that, in turn cased the adapter to be notified by notifyItemRangeInserted() even though the same number of items are in the new list. So pay close attention to how you implement the DiffUtils callbacks!

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
