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。

我也遇到过同样的情况。 在你清理你的收藏之前，通过添加代码来解决这个问题。

mRecyclerView.getRecycledViewPool () .clear ();

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。

我有一个(可能)相关的问题-进入一个新的实例的活动与RecyclerView，但与一个较小的适配器触发这个崩溃为我。

RecyclerView.dispatchLayout()可以在调用mrecycle . clearoldpositions()之前尝试从废品中提取项目。结果是从公共池中提取位置高于适配器大小的项。

幸运的是，它只这样做，如果PredictiveAnimations启用，所以我的解决方案是子类GridLayoutManager(线性layoutmanager有同样的问题和“修复”)，并覆盖supportpredictiveitemanimations()返回false:

/**
 * No Predictive Animations GridLayoutManager
 */
private static class NpaGridLayoutManager extends GridLayoutManager {
    /**
     * Disable predictive animations. There is a bug in RecyclerView which causes views that
     * are being reloaded to pull invalid ViewHolders from the internal recycler stack if the
     * adapter size has decreased since the ViewHolder was recycled.
     */
    @Override
    public boolean supportsPredictiveItemAnimations() {
        return false;
    }

    public NpaGridLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    public NpaGridLayoutManager(Context context, int spanCount) {
        super(context, spanCount);
    }

    public NpaGridLayoutManager(Context context, int spanCount, int orientation, boolean reverseLayout) {
        super(context, spanCount, orientation, reverseLayout);
    }
}

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() ; 
 }

}

当我没有意识到我同时调用了两次不同的线程时，问题就发生了。

notifyDataSetChanged

一个来自sqlite加载函数，一个来自调用函数后

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:)。
