2 |
3 | ##控件简介
4 | AnimationBanner是一个利用属性动画原理实现的横幅广告控件。
5 |
6 | ##控件特点
7 | 1.实现原理简单，使用方便
8 | 2.可灵活设置Banner数量，1张或N张
9 | 3.附带Indicator小圆点指示器，并自动联动
10 | 4.可指定Indicator指示器在Banner中的位置
11 | 5.可自定义Indicator小圆点半径，处于当前位置或非当前位置时的颜色
12 | 6.可配置动画持续时间来调整Banner滑动的速度
13 | 7.可自定义Banner的大小以适配图片
14 | 8.可响应Banner滑动与点击事件
15 |
16 | ##实现原理
17 | 请参考之前的一篇博客 [利用Android属性动画实现Banner的原理与实践](http://blog.csdn.net/ahence/article/details/46646559)
