ListBuddies is an Android library that implements a pair of auto-scrolling circular parallax ListViews, mirroring the functionality seen on the Expedia app's home screen. It allows developers to easily add a visually appealing and interactive carousel-like experience to their applications. The primary technology involves extending CircularLoopAdapter and customizing the getCircularCount and item retrieval methods to achieve the desired parallax effect during both automatic and manual scrolling.
Notable features include the implementation of smooth, circular parallax scrolling with adjustable speed and gap settings. The architecture allows for customization of list dividers and feedback mechanisms for item clicks. The library offers clear usage instructions and a straightforward extension point for creating custom adapters, ensuring ease of integration and adaptation to various application needs. It uses a minimal extension from a base adapter.
- Auto-scrolling Parallax: Implements a visually engaging circular parallax scrolling effect for list views.

The library is not actively maintained and no further releases are planned. The last commit was in October 2019, and the project has a moderate number of stars and forks, suggesting past community interest. Documentation is present, though potentially outdated. While functional, users should be aware of the lack of ongoing support and potential compatibility issues with newer Android versions.
ListBuddies is beneficial for developers seeking to replicate the distinctive visual appeal of circular parallax scrolling in their Android applications. It is well-suited for scenarios where showcasing a set of items in a dynamic and engaging manner is desired, offering a valuable alternative to traditional list view implementations. It is a good option if a pre-built circular parallax list view is needed and customization needs are limited.
