## What it is
An Android layout view library that lets developers describe relative view positions using Java-style expressions in XML layout params, such as layout_left="view1.right+10dp". It supports percentages, references to sibling views by id, and keywords like prev, next, parent, and screen.

## Use cases
- position android views relative to each other with expressions
- replace nested linearlayout and relativelayout with a single layout
- build percentage-based responsive android layouts
- align views to other views' edges in xml
- create adaptive layouts that reference screen size

## When to choose
- you need expressive relative positioning beyond what RelativeLayout offers
- you want to flatten deeply nested view hierarchies
- you prefer declaring layout math directly in XML attributes

## When to avoid
- you are starting a new project where Jetpack ConstraintLayout is available
- you need a library with active maintenance and recent releases
- you only need simple linear or frame layouts

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, frontend-framework
- domain: mobile-development, android-tools, web-design
- platform: jvm
- tags: layout-engine, constraint-layout, xml-layouts, relative-positioning, ui-layout, android
