一個運動驅動的Android動畫框架：Backboard

一個運動驅動的Android動畫框架。backboard是一個在rebound之上的框架，讓它更加易于使用通過連接到的視圖和動作。backboard-example is an Android app with a few demos of animations made possible by backboard.

Usage

Update yourbuild.gradlewith

dependencies {
   compile 'com.非死book.rebound:rebound:0.3.8' compile 'com.tumblr.backboard:backboard:+' }

Getting Started

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));
