i have viewpager and fragments for each tabs ....
first tab fragment has subfragments/childfragment
Tab1 ----> FragmentA -----> recyclerview click --->FragmentB
Tab2 ----> FragmentC

i have recyclerview in my activity now i have to show that recyclerview which is inside appbarlayout .... only in Homefragment.
While another fragmentB open on recyclerview click of HomeFragment.

now i just want to show appbarlayout only in case of fragmentA whle it should be hidden in all other cases .... so i resolved using   @Override
    public void setUserVisibleHint(boolean isVisibleToUser) {

        isVisible = isVisibleToUser;
        super.setUserVisibleHint(isVisibleToUser);
        // Make sure that fragment is currently visible

        if(isVisible && getActivity() != null)
        {
            ((HomeActivity)getActivity()).hideShowCategoryRecyclerView(true);
        }
    }
but this method in FragmentA is not getting called when i tab Second fragment ... then again FragmentA ...
which method will be called ?
