Rexsee API介绍：Animations动画学习笔记及源码

在Android上实现动画，官方的SDK提供了Animations，并且介绍了两种不同模式，分别是：
1. Tween Animation：通过对场景里的对象不断做图像变换(平移、缩放、旋转)产生动画效果，即是一种渐变动画；
2. Frame Animation：顺序播放事先做好的图像，是一种画面转换动画。
同时，Animation由四种类型组成：
XML文件：
· alpha 渐变透明度动画效果
· scale 渐变尺寸伸缩动画效果
· translate 画面转换位置移动动画效果
· rotate 画面转移旋转动画效果
在Java 源码中定义了相应的类，可以使用这些类的方法来获取和操作相应的属性：
· AlphaAnimation 渐变透明度动画效果
· ScaleAnimation 渐变尺寸伸缩动画效果
· TranslateAnimation 画面转换位置移动动画效果
· RotateAnimation 画面转移旋转动画效果
具体Android的原生就不再多说了，相对复杂，有兴趣的可以直接去看google的SDK。这里分享了Rexsee的API，基于对原生的封装，可以直接使用JS实现功能调用。如：
【事件】 void onAnimationStart(String id)
【说明】 当动画开始播放时触发。
