cymcsg/ultimaterecyclerview

In Android app development, RecyclerView is the standard component for displaying long scrollable lists of items. It handles scrolling and item reuse efficiently, but it does not include features that most apps need, like pull-to-refresh or automatically loading more items when the user reaches the bottom of the list. UltimateRecyclerView is a library that wraps RecyclerView and adds those features so developers do not have to build them separately. The added features include pulling down at the top of the list to trigger a refresh, loading more items automatically when the user scrolls to the bottom (often called infinite scrolling), swiping an item sideways to delete it, dragging items to rearrange their order, several animation styles for list items, a parallax header image that scrolls at a different speed than the list content, sticky section headers that stay pinned at the top of the screen as you scroll past them, and a toolbar or floating action button that appears or disappears based on scroll direction. The library is added to an Android project through Gradle or Maven. In a layout file, usage looks the same as a standard RecyclerView: you replace the usual tag with UltimateRecyclerView. The library supports AndroidX. The README notes the project is under active development. The version log covers updates from v0.3.x through v0.9.0, with notable milestones including AndroidX migration and a revised adapter class. A demo app showing the features is available on Google Play and as a downloadable APK on the releases page. A wiki provides additional usage examples. The library assembles features from several open-source projects, which are credited in the README, including separate libraries for animations, swipe gestures, pull-to-refresh styles, and sticky headers. The project is released under the Apache 2.0 license.
