解决方案
使用viewpager+4个fragment
每个fragment中为swiperefreshlayout+recyclervie
出现上述错误，最终错误原因不在StaggeredGridLayoutManager，而是viewpager的状态保存
解决方法：
viewpager.setOffscreenPageLimit(list.size() - 1);

If your RecyclerView is in a Fragment and your Fragment is in ViewPager, and you didn't set viewpager.setOffscreenPageLimit(MAX_ITEM_SIZE), this crash will some times happen unexpectedl
I was suffering same crashes. I can't reproduce it, and don't know why it would happen till now. But after I set the off-screen page limit, this crash goes away.
Wish it helps.
