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.

我正在使用RecyclerView显示项目的名称.我的行包含单行TextView.项目名称存储在List<String> mItemList.
要更改内容RecyclerView,我替换字符串mItemList并调用notifyDataSetChanged()RecyclerViewAdapter.
但是如果我尝试更改mItemListRecyclerView滚动时的内容,有时它会给我
java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 157(offset:157).state:588
如果尺寸mItemList小于之前,就会发生这种情况.那么改变内容的正确方法是RecyclerView什么？这是一个错误RecyclerView吗？

at …你们能帮助我吗？
这是我添加片段的代码
mRecyclerView.addOnItemTouchListener(
new RecyclerItemClickListener(getActivity(), new RecyclerItemClickListener.OnItemClickListener() {
@Override
public void onItemClick(View view, int position) {
if (!IsScrolling) {
Fragment fragment = new ProductInfoFragment();
Bundle bundle = new Bundle();
bundle.putString("prodID", mItems.get(position).getproductID());
bundle.putString("catName", catName);
fragment.setArguments(bundle);
FragmentManager fragmentManager = getActivity().getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
fragmentTransaction.add(R.id.fragmentContainer, fragment, "ProuctInfoFragment");
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
mItems.clear();
}
}
})
);
但是,当我从添加的片段中按回来时,我收到此错误并且我的应用程序崩溃了.
