## What it is
FastAdapter is a Kotlin library that simplifies building RecyclerView adapters on Android, handling item views, click listeners, selection, and more with minimal boilerplate. It ships modular extensions for expandable items, drag & drop, sticky headers, filtering, endless scroll, and swipe gestures.

## Use cases
- build a recyclerview adapter with less boilerplate
- add multi-select to an android list
- implement swipe-to-dismiss on list items
- create expandable list items in recyclerview
- add sticky headers to a recyclerview
- implement endless scroll / infinite loading list
- handle click and long-click listeners on list items

## When to choose
- you build Android list/grid UIs with RecyclerView and want to cut adapter boilerplate
- you need selection, expandable items, drag & drop, or swipe actions out of the box
- you want a well-maintained, widely used Kotlin adapter library

## When to avoid
- you use Jetpack Compose lists instead of RecyclerView
- your project is not Android/Kotlin
- you need a fully custom adapter architecture the library's item model can't express
