## What it is
An Android library providing a RecyclerView with an automatically generated alphabetical index bar, sticky section headers, and customizable header/footer views. It uses TinyPinyin for fast pinyin conversion, making it ideal for Chinese contact or city pickers.

## Use cases
- build a city selection screen with an A-Z index bar
- create a contact list with sticky section headers
- add an alphabet sidebar to a RecyclerView list
- sort Chinese names by pinyin in an Android list
- implement a fast-scrolling indexed list on Android

## When to choose
- you need an indexed, sticky-header list (contacts, cities) in an Android app
- you want automatic pinyin-based sorting for Chinese data
- you need customizable header/footer views in an indexed list

## When to avoid
- your project uses Jetpack Compose rather than the View/RecyclerView system
- you need a maintained library - the last release was in 2018
- you only need a plain list without index or sticky features
