Backboard is a framework on top of rebound that manages howSpringsare used and simplifies the most common use cases:
- Actions, such asMotionEvents, are mapped toSpringsviaImitators.
- Springsare mapped toViewsand view properties viaPerformers.
In addition, anActorwraps the above objects and provides a simple interface for mapping touch motion to a view's position - dragging.
Performers
APerformertakes the current value of aSpringand sets it as the value of a view property.
Spring bounce = SpringSystem.create().createSpring(); Performer xMotion = new Performer(view, View.TRANSLATION_X); bounce.addListener(xMotion);
for those saving screen space, a fluent interface is available:
Spring bounce = SpringSystem.create().createSpring().addListener(new Performer(view, View.TRANSLATION_X));
