RecyclerView开发中不常见bug解决

来源：互联网发布：js文件什么样编辑：程序博客网时间：2024/05/21 06:55

java.lang.IndexOutOfBoundsException

Inconsistency detected. Invalid view holder adapter positionViewHolder{31b397f1 position=3 id=-1, oldPos=-1, pLpos:-1 no parent}

android.support.v7.widget.RecyclerView$Recycler.validateViewHolderForOffsetPosition(RecyclerView.java:4505)

其实也不是什么解决方法，只是把这个异常捕获了，不让他奔溃了，这个问题的终极解决方案还是得让google去修复。

1、创建一个类LinearLayoutManagerWrapper继承LinearLayoutManager，重写onLayoutChildren方法

public class WrapContentLinearLayoutManager extends LinearLayoutManager {    public WrapContentLinearLayoutManager(Context context) {        super(context);    }    public WrapContentLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {        super(context, orientation, reverseLayout);    }    public WrapContentLinearLayoutManager(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();        }    }}

2、设置RecyclerView的布局管理为WrapContentLinearLayoutManager对象

mRecyclerView.setLayoutManager(new WrapContentLinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
