wasabeef/recyclerview-animators

The \animators\ library has been rewritten in Kotlin, introducing a new \AnimationAdapter\ base class that properly initializes and delegates \hasStableIds\ to the wrapped adapter. This ensures that RecyclerView item animations (such as FadeIn, ScaleIn, and SlideIn variants) correctly preserve stable ID behavior, allowing for more efficient list updates and smoother visual transitions when items are added, removed, or changed.

The example application's source files in example/src/main/java have been converted from Java to Kotlin. The activities (MainActivity, AnimatorSampleActivity, AdapterSampleActivity) and supporting classes (MainAdapter, MyAnimationAdapter, MyAnimator, SampleData) now use Kotlin syntax and AndroidX libraries, providing a modern, idiomatic Kotlin implementation of the library's usage examples.

example/src/main/java · high confidence

The library has been rewritten in Kotlin (version 4.0.0), raising the minimum SDK to 21 and targeting SDK 30. This change improves code reliability and aligns the project with modern Android development practices, while also updating build tools and disabling Jetifier.

(repo-wide) · high confidence

The project has been migrated to AndroidX, updating the support library dependencies to their AndroidX equivalents (e.g., androidx.appcompat, androidx.recyclerview). The build system has been updated to use Kotlin for the library and example modules, and Gradle dependencies have been upgraded to support AndroidX and Kotlin 1.3.72.

(dependencies) · high confidence

The Gradle wrapper has been updated to use Gradle version 6.7.1. This change ensures that the project uses a specific, stable version of the Gradle build tool, improving build consistency across different environments.
