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。

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 );
        }

它还可以与在同一时间多次设置适配器有关。我有一个回调方法，在同一时间被触发5-6次，我在那个回调中设置适配器，因此RecycledViewPool不能同时处理所有这些数据。机会不大，但你最好还是去看看。

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();

您可以按以下方式重现此崩溃

清除适配器项list.clear()。(不调用notify方法) 滚动回收视图。

因此，我假设当您从列表中删除项目并滚动而没有调用notify方法时发生崩溃

林特给了我一个关于不一致性的建议: 我写了(onBindViewHolder()):

pholder.mRlayout.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        doStuff(position);
                    }
                });

它必须被替换为:

pholder.mRlayout.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        doStuff(pholder.getAdapterPosition());
                    }
                });

在你的代码中运行这两个代码，然后运行Lint得到完整的解释!!

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
