```
public class FastScroller.Delegate

                    
```
This class links the FastScroller to the RecyclerView.To use FastScroller in your existing adapter (Not FlexibleAdapter), follow the steps below:
- In your layout, include @layout/fast_scroller after the RecyclerView.
- Implement FastScroller.AdapterInterface in your adapter.
- In your adapter, create a FastScroller.Delegate and call the delegate methods: {@code onAttachedToRecyclerView}, {@code onDetachedFromRecyclerView} and {@code setFastScroller}.
- If {@code fastScrollerBubbleEnabled} is true, in your adapter, implement BubbleTextCreatorand add the logic to display the label in {@code onCreateBubbleText}.
- In the fragment/activity call the adapter's {@code setFastScroller} after setting theRecyclerView's adapter.
