出问题的代码：

FragmentManager childFragmentManager = getChildFragmentManager();
GridLayoutManager gridLayoutManager = new GridLayoutManager(getContext(), 2);
recyclerView.setLayoutManager(gridLayoutManager);
XXXRecyclerAdapter adapter = new XXXRecyclerAdapter(getContext(), childFragmentManager, mList, mBannerLists, new IXXRecyclerUpdateCallback() {
...

参考：https://stackoverflow.com/questions/43562394/fragment-has-not-been-attached-yet

应该是操作了没有attach的Fragment，需要判断下if(mFragment.isAdded()){ //do }

于是在“getChildFragmentManager()”前添加判断：

if (!isAdded()) return;

先这样，再有报错再更新。。。
