You can try this approach:

  mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener()
{
    @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        if (dy > 0) //check for scroll down
        {
            visibleItemCount = mLayoutManager.getChildCount();
            totalItemCount = mLayoutManager.getItemCount();
            pastVisibleItems = mLayoutManager.findFirstVisibleItemPosition();

            if (loading) {
                if ((visibleItemCount + pastVisibleItems) >= totalItemCount) {
                    loading = false;
                    if (adapter.countOfShowing < adapter.allChallenges.size()) {
                        Log.e("...", "Last Item Wow !");
                        adapter.increaseCountOfShowing();
                        adapter.notifyDataSetChanged();
                    }
                    loading = true;
                    //Do pagination.. i.e. fetch new data
                }
            }
        }
    }
});
