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()));
