firebaseui

I dont like to show empty RecyclerView to users. I know there is getItemCount method in recyclerview, but i think reyclerview is executed on separate thread maybe. Its because whenever i try to call adapter.getitemcount it gives count 0 quickly even when my recyclerview will have values coming from firebase. So i think maybe till the values come the getItemCount method is executed before and returns 0 or maybe it is executed on separate thread. But either way i get 0 even when my recyclerview has values coming from firebase. So i want to check if my firebase recycler is empty or not and then
