## What it is
An Android library providing a RecyclerView ItemDecoration that renders pinned (sticky) section headers across LinearLayoutManager, GridLayoutManager, and StaggeredGridLayoutManager. It supports large and small headers, click/double-click/long-press events on headers and children, and customizable separator lines.

## Use cases
- add sticky section headers to a RecyclerView list
- pin group headers while scrolling a grid layout
- show pinned headers in a staggered grid waterfall layout
- handle clicks and long presses on sticky headers
- build a stock market list with pinned category headers
- draw custom separator lines between list sections

## When to choose
- you need sticky section headers on Android RecyclerViews with linear, grid, or staggered grid layout managers
- you want header and child click handling built into the decoration
- you need a mature Java-based Android UI library with an Apache-2.0 license

## When to avoid
- you are not developing for Android or not using RecyclerView
- you need horizontal orientation support, which is not provided
- you want an actively maintained project - the latest release dates to 2019 and the author recommends a newer StickyItemDecoration library
