问题描述
清除适配器并调用notifyDataSetChanged()时- StaggedGridLayoutManager 管理器在Span[]实例中仍然具有mCachedStart/End.因此，当您向适配器中添加新项目时，布局管理器会绘制具有偏移量的项目，这是一个巨大的问题.
When you clear your adapter and call notifyDataSetChanged() - StaggedGridLayoutManager manager still has mCachedStart/End in Span[] instances. So when you add new items to adapter - layout manager draws items with offset, and this is a huge problem.
EtsyStaggeredGridView 具有方法resetToTop()，该方法清除所有缓存的内容并从头开始绘制所有内容.
EtsyStaggeredGridView has method resetToTop() which clears all cached stuff and draws everything from scratch.
有一些解决方法:

layoutManager.onDetachedFromWindow(recyclerView, null) - 设置新布局管理器，该管理器不好
- Call
layoutManager.onDetachedFromWindow(recyclerView, null)after clearing an adapter - Set new layout manager which is bad
