RecyclerView doesn't update his item's layouts

I have a RecyclerView which contains TextViews as items. When I click on a item, it selects him and it normally changes layout of the TextView.

However, TextView's layout doesn't update except if I scroll the RecyclerView. In back the item is selected, but in front, I have to scroll the RecyclerView to see the change.

For information, my RecyclerView is in a Fragment which is in a ViewPager2.

I use notifyItemChanged()and I tried with notifyDataSetChanged(). I've also tried with requestLayout()and invalidate() on the RecyclerView and Parent's layout.

EDIT 2 :

I've found the source of my problems, see this post to check out.

Sorry about my poor English ! Is it works on Android5.1 or Android6.0,I have the same problem .finally I find a solution

1. add a ListView(you can set the height or width to zero make it invisiable) to the Fragment where RecyleView in

2. set a Adapter to ListView

then the RecyclerView in this fragment can notifyDataSetChanged() correctly ,even the RecyclerView in other fragment of the same ViewPager2 can work correctly, I don't know how it works ,but it works for me ,hope it works for you too
