How to load more data in RecyclerView when Scrolling on Android

So step by step:

  1. Add OnScrollListener to your RecyclerView to detect when you want to load more (for example load more if you are at last item)

  2. Create an interface for the more loading:

    public interface OnLoadMoreCallback { void onLoadMore(); }

  3. Implement the interface. Inside the onLoadMore() you can call for example a rest api. For this you can use AsyncTask.

  4. After you loaded new data you have to update the datamodels and notify your adapter that the data has been added.
