我们的QA检测到一个错误:当旋转Android设备(Droid Turbo)时,发生以下与RecyclerView相关的崩溃:

java.lang.IndexOutOfBoundsException:检测到不一致.无效的项目位置2(偏移量:2).state:3

对我来说,它看起来像RecyclerView内部的一个内部错误,因为我无法想到这是由我们的代码直接导致的任何方式......

有谁遇到过这个问题？

什么是解决方案？

一个残酷的解决方法可能是在发生异常时捕获异常并从头开始重新创建RecyclverView实例,以避免陷入损坏状态.

但是,如果可能的话,我想更好地理解这个问题(并且可能在其源头修复它),而不是掩盖它.

这个bug很难重现,但是当它发生时它是致命的.

我试图得到的高度和宽度ImageView的Fragment有以下ViewTreeObserver:

import android.view.ViewTreeObserver;
import android.view.ViewTreeObserver.OnGlobalLayoutListener;

private ImageView imageViewPicture;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_general_activity_add_recipe, container, false);
    setHasOptionsMenu(true);

    ...

    final ViewTreeObserver observer = imageViewPicture.getViewTreeObserver();
    observer.addOnGlobalLayoutListener (new OnGlobalLayoutListener () {
        @Override public void onGlobalLayout() {
            observer.removeGlobalOnLayoutListener(this);
        }
    });

    return view;
}

运行此代码会导致以下异常:
