Native Bug of Android RecyclerView-Inconsistency detected. Invalid view holder adapter positionViewHolder {a1bbfa3 position = 2 id =-1, oldPos =-1, pLpos:-1 no parent}, recyclerviewholder

Today, when I was running my own App, I suddenly found the App to crash while it was running. Then I checked the Log of Android Studio and found this error. I checked it online, this is the native Bug of RecyclerView. This Bug occurs when data is updated. The error is displayed

java.lang.IndexOutOfBoundsException: Inconsistency detected.

I can see that the error does not refer to the code I wrote, so it is determined that it is a native Bug.

The solution to the error is to customize a LayoutManager and rewrite the onLayoutChildren method. In this case, an exception is thrown directly.

The code is

package com.zhangmiao.developmenthelperdemo;import android.content.Context;import android.support.v7.widget.LinearLayoutManager;import android.support.v7.widget.RecyclerView;import android.util.AttributeSet;/** * Created by zhangmiao on 2016/12/7. */public class MyContentLinearLayoutManager extends LinearLayoutManager {    public MyContentLinearLayoutManager(Context context){        super(context);    }    public MyContentLinearLayoutManager(Context context,int orientation,boolean reverseLayout){        super(context,orientation,reverseLayout);    }    public MyContentLinearLayoutManager(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){            e.printStackTrace();        }    }}

Modify the setLayoutManager parameter of RecyclerView to WrapContentLinearLayoutManager.

The Code is as follows:

 recyclerView.setLayoutManager(new WrapContentLinearLayoutManager(mView.getContext()));
