Recyclerview with separator, material scroller and letters

Question

I'm trying to create a Recyclerview that looks like this (taken from Telegram contacts list)

It should have

1. Letters
2. Material scroller with letters
3. Separator between different letters

It should load names from a txt file in the assets folder and images from the drawable folder. Right now I'm using a simple list view with images and names, but how can I implement these features with a recyclerview? Thanks.

Answer 1

For 1 and 2 you can use this Library and for the 3rd you can use following code in List item.

 <View  
android:layout_width="fill_parent"
android:layout_height="2dp"
android:background="#c0c0c0"/>
