RecyclerView scroll listener to AbsListView scroll listener

RecyclerToListViewScrollListener

public class RecyclerToListViewScrollListener extends RecyclerView.OnScrollListener {
  private final AbsListView.OnScrollListener scrollListener;
  private int lastFirstVisible = -1;
  private int lastVisibleCount = -1;
  private int lastItemCount = -1;

  public RecyclerToListViewScrollListener(AbsListView.OnScrollListener scrollListener) {
    this.scrollListener = scrollListener;
  }
  
  @Override
  public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
    LinearLayoutManager layoutManager = (LinearLayoutManager) recyclerView.getLayoutManager();
    
    int firstVisible = layoutManager.findFirstVisibleItemPosition();
    int visibleCount = Math.abs(firstVisible - layoutManager.findLastVisibleItemPosition());
    int itemCount = recyclerView.getAdapter().getItemCount();
    
    if (firstVisible != lastFirstVisible || visibleCount != lastVisibleCount
        || itemCount != lastItemCount) {
      scrollListener.onScroll(null, firstVisible, visibleCount, itemCount);
      lastFirstVisible = firstVisible;
      lastVisibleCount = visibleCount;
      lastItemCount = itemCount;
    }
  }
}

Line 22 should be:
lastVisibleCount = visibleCount

Yup thanks!
