'I want to hide my appBarLayout and BottomNavigationView on scroll of fragment recycler?
I want to hide my appBarLayout and BottomNavigationView at the same time when I scroll up the recycler and show again when I scroll down the recycler.
In my case I have an activity in which appBarLayout and BottomNavigation is but my recycler is in fragment which is replaced at the container place, when I scroll recycler from fragment I want to hide appBarLayout and BottomNavigationView from my main activity.
Here is my MainActivity class XML file.

</LinearLayout>
and through this method I am sending callback of recycler scroll to my main activity
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
setVideoPlayer(true);
Log.i(TAG, "onScrolled: dy :- "+dy);
Log.i(TAG, "onScrolled: recyclerView :- "+recyclerView);
Log.i(TAG, "onScrolled: dx :- "+dx);
if (dy > 0){
mainStudentActivity.hideToolbar();
}else{
mainStudentActivity.showToolbar();
}
}
