Android StaggeredGridLayoutManager offset bug

Question

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 has method resetToTop() which clears all cached stuff and draws everything from scratch.

There are some workarounds:

• Call layoutManager.onDetachedFromWindow(recyclerView, null) after clearing an adapter
• Set new layout manager which is bad
