Answer 1

you can get the on-screen item count as follow

RecyclerView recyclerView = findViewById(R.id.recyclerview);
LinearLayoutManager layoutManager = new LinearLayoutManager(context);
recyclerView.setLayoutManager(layoutManager);

//get on-screen items count.
int currentItems = layoutManager.getChildCount();

//get total items count.
int totalItems = layoutManager.getItemCount();

//get scroll-out items count
int scrollOutItems = layoutManager.findFirstVisibleItemPosition();
