## What it is
FlexibleAdapter is a Java library for Android that consolidates many RecyclerView Adapter features—multi-select with ActionMode, drag & drop, swipe, expandable items, sticky headers, endless scroll—into one library. It is now an archived, API-frozen legacy project published to Maven Central for apps still using the Android View (XML) system.

## Use cases
- implement multi-select with action mode in a RecyclerView list
- add drag-and-drop reordering and swipe-to-dismiss to Android lists
- show expandable/collapsible list items with sticky headers
- implement endless scrolling and fast scroll in RecyclerView
- add undo and selection coherence to list interactions
- filter and search items in a RecyclerView adapter

## When to choose
- your Android app uses the legacy View/XML system and needs a feature-rich RecyclerView adapter
- you want one stable library instead of several incompatible adapter libraries
- you need a mature, frozen API that won't change under you

## When to avoid
- you are starting a new Android project—use Jetpack Compose LazyColumn/LazyRow instead
- you target Kotlin Multiplatform or Compose Multiplatform
- you need new features or active bug-fix support

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, state-management, animation
- domain: mobile-development, android-tools, frontend
- platform: jvm
- tags: recyclerview, adapter, multi-select, drag-and-drop, swipe-to-dismiss, expandable-items, sticky-headers, endless-scroll, jetpack-compose-migration, legacy-archive, android, mobile
