Using TabLayout and ViewPager in fragment

Question

I'm using Tablayout in fragment, and there is no problem.

but when i click on items and open details fragment (i add the new fragment in back stack) after pop back stack, The Tablayout root fragment just show tabs and viewPager is empty.

How can i solve this problem?

try to use notifyDataSetChanged() for the adapter, after you do - pop back stack. — Igor Fridman, Aug 26 '17 at 13:43
