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
