【中文标题】检测到不一致的无效视图持有者适配器错误

【英文标题】：Inconsistency Detected Invalid View Holder Adapter Error

【发布时间】：2021-11-29 15:25:22

【问题描述】：

我为我的学校项目制作了一个使用 Firestore 运行的应用程序。当我添加第一个查询时没有问题，但如果我想添加第二个并返回MainActivity，我会收到此错误并且应用程序死亡。

【问题讨论】：

adapter.startListening() 会发生什么？例外肯定在你的MainActivity/NoteAdapter

您在哪一行代码中遇到了这个错误？

我不知道哪一行给出了该错误。只有当我向 Firestore 添加新数据时才会发生这种情况

@caneraltuner 可以参考一下链接吗：***.com/questions/31759171/… 有用吗？

@DivyaniYadav 它帮助了我，谢谢。

【参考方案1】：

我解决了我的问题。问题发生在MainActivity，它是由RecyclerView在不同线程中修改的数据引起的。检查所有数据访问并包装LinearLayoutManager 将被视为一种解决方案。

我写了@sakiM 在第一次回答时给出的代码：RecyclerView and java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder in Samsung devices 代码如下：

public class WrapContentLinearLayoutManager extends LinearLayoutManager 
    public WrapContentLinearLayoutManager(Context context) 
        super(context);
    

    public WrapContentLinearLayoutManager(Context context, int orientation, boolean reverseLayout) 
        super(context, orientation, reverseLayout);
    

    public WrapContentLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) 
        super(context, attrs, defStyleAttr, defStyleRes);
    

    @Override
    public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) 
        try 
            super.onLayoutChildren(recycler, state);
         catch (IndexOutOfBoundsException e) 
            Log.e("TAG", "meet a IOOBE in RecyclerView");
        
    

然后我将我的RecyclerView 匹配到WrapContentLinearLayoutManager

代码如下：

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view); recyclerView.setLayoutManager(new WrapContentLinearLayoutManager(this,LinearLayoutManager.VERTICAL,false));

谢谢大家，祝你有个愉快的一天
