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

今天在運行自己編寫的App時，突然發現App在運行時閃退，然後就查看了Android Studio的Log，發現了這個錯誤，上網查了一下，才知道是RecyclerView的原生Bug，在資料更新時會出現這個Bug，錯誤顯示為

可以看到錯誤並沒有指到我自己所寫的代碼，所以斷定是原生的Bug。

錯誤解決的方式是自訂一個LayoutManager，重寫onLayoutChildren方法，在遇到這個異常時，直接拋出異常。

代碼為

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();        }    }}

然後將RecyclerView的setLayoutManager的參數修改為WrapContentLinearLayoutManager。

代碼如下：

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