What do you think. X likes this. I had it before in another Android phone, but on Android 6 and I had to install it as a module of Xposed. The default gesture there for scroll to top or bottom is 3 finger swipe that's the same as OP5 gesture for taking screenshot, but you can change it in application settings to another - I use 2 fingers swipe.

Fast Scrolling in RecyclerView Using Support Library - knowledge Transfer

When setting up the fast scroller with your RecyclerView, you have to provide a mapping function that returns the fast scroll indicator that's desired if any to represent a section in the list. In this function, return a Text if you want this position's section to be represented by a text indicator typically its starting letter for an alphabetical list , return an Icon if you want an icon, or return null if you don't want this section to be shown in the fast scroller.

Indicators in the fast scroller won't have any duplicates.

You should return identical FastScrollItemIndicator s for each item in your list that belongs to the same section. This often happens implicitly; if your database model contains a section field and you create a FastScrollItemIndicator. Text based on it, all items with the same section will be grouped together in the fast scroller. Similarly, if a list is alphabetical, creating a FastScrollItemIndicator.

Text with the first letter of each item's name will result in all items starting with the same letter to be grouped together.

The fast scroller can be set up to filter out certain indicators from being shown. For example, this can be used to hide some indicators if the screen is too short to fit them all. By default, the fast scroller handles scrolling the RecyclerView to the right section when it's pressed. However, in case you want to override this behavior, you can set useDefaultScroller to false and set up a callback with the fast scroller to handle it yourself.
