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。

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 (Exception 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()));

还有一种异常：
java.lang.IllegalArgumentException: Called attach on a child which is not detached: ViewHolder{ec75dcb position=18 id=-1, oldPos=-1, pLpos:-1 not recyclable(1)} android.support.v7.widget.RecyclerView{b3515af VFED..... ......ID 0,0-1080,1230 #7f0900ec app:id/recycleView}, adapter:com.xgh.app.demo2.CouponListAdapterdemo@68fbdbc, layout:com.xgh.app.demo2.WrapContentLinearLayoutManager@26b4145, context:com.xgh.app.demo2.DemoActivity@6973c1d

参考了各种资料，list的数据，要和adpater数据同步，例如，list.clear(),执行后，要立即调用notifyDataSetChanged()，而不是等到网络请求完后，在调用notifyDataSetChanged()。意思是每当list集合改变时，就立马调用通知。
测试后不再报异常。希望对大家有帮助。
