I found an answer here that, I believe, is much better than most I've seen on SO and elsewhere.

The idea is simple: in onScrolled in your RecyclerView's ScrollListener, check if the last completely visible item is the last item in your data set.

        if(llm.findLastCompletelyVisibleItemPosition() == data.length() -1){
            //bottom of list!
            loadMoreData();
        }

This happens with a method in the LinearLayoutManager. Calling LinearLayoutManager#findLastCompletelyVisibleItemPosition() can comparing it to the position of the last item in your dataset let's you know when you can load more.

I haven't tried this for the GridLayoutManager.

UPDATE

LinearLayoutManager#findLastVisibleItemPosition() is a better alternative to LinearLayoutManager#findLastCompletelyVisibleItemPosition(), especially when your items are longer than the window height.
