    public boolean getPageStart(int page) {
        return 0;
    }
    @Override
    public void onNextPage(int page) {
        if (loadItemSuccess) {
            populateItems(); // add items to adapter
            notifyLoadingCompleted();
        }
        if (reachPageEnd) {
            notifyPaginationFinished();
        }
    }
}

Attach Pagination to PaginatedRecyclerView

recyclerView.setLayoutManager(lm)
recyclerView.setAdapter(adapter)
recyclerView.setPagination(pagination)

Customization

Use custom loading row

Create custom loading adapter, and supply it to PaginatedRecyclerView.

public class CustomLoadingAdapter extends LoadingAdapter {
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        ...
    }
}
CustomLoadingAdapter placeholderAdapter = new CustomLoadingAdapter();
recyclerView.setLoadingAdapter(placeholderAdapter);
