今天在运行自己编写的App时，突然发现App在运行时闪退，然后就查看了Android Studio的Log，发现了这个错误，上网查了一下，才知道是RecyclerView的原生Bug，在数据更新时会出现这个Bug，错误显示为

java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder{431a7450 position=1 id=-1, oldPos=-1, pLpos:-1 scrap [attachedScrap] tmpDetached no parent}

可以看到错误并没有指到我自己所写的代码，所以断定是原生的Bug。

错误解决的方式是自定义一个LayoutManager，重写onLayoutChildren方法，在遇到这个异常时，直接抛出异常。

代码为

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();

        }

    }

}

然后将RecyclerView的setLayoutManager的参数修改为WrapContentLinearLayoutManager。

代码如下：

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