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，在數據更新時會出現這個Bug，錯誤顯示為

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定義一個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()));
