Contour is a Kotlin-first Android layout library that lets developers define view position and size with executable lambdas instead of XML constraints, acting as a thin typesafe wrapper around Android's layout APIs. It is now deprecated, with development ceased in favor of Jetpack Compose.
Use cases
- build android layouts in pure kotlin without xml
- define view constraints as lambdas instead of xml
- replace constraintlayout xml with programmatic layout code
- create dynamic layouts that adapt to screen size at runtime
- avoid findViewById and R.id ambiguity in android views
- do runtime a/b testing of android ui components
When to choose
- maintaining an existing android app already built with Contour
- you want programmatic kotlin-only layouts on a legacy non-Compose codebase
When to avoid
- starting a new android project - use Jetpack Compose instead
- you need a library with active development and community support
- your team prefers xml or standard constraintlayout workflows
