Scaloid
Scaloid makes your Android code easy to understand and maintain
...For example, it offers DSL-style helpers for defining views and layouts with less boilerplate, implicit conversions to help with event listeners, and utility methods to simplify common tasks. Scaloid aims to capture the expressiveness of Scala—higher-order methods, implicit conversions, extension methods—to let Android development be more functional and succinct. It lowers friction for Scala developers targeting Android, making UI code more compact and composable while still maintaining access to full Android platform capabilities.
