**Android记录4--自定义ToggleButton+用SharedPreferences保存用户配置**

2013年8月14日Android记录

很多应用都会有用户设置，用户的一些偏好可以由用户来决定那是应用人性化的体现，在实际开发中很多情况都作成可配置的了，本篇博客要介绍的是一个比较炫的状态按钮切换，我想很多开发者都想做出这样的效果，在这里我也就把自己参与的项目当中的这部分实现，做出Demo来于朋友们分享。

没有图，我感觉就特别不舒服：

这样看没办法看出效果，如果能做出动态图就好了，下次吧。

除了ToggleButton的自定义之外，用户配置的信息也是要保存起来的，每一次启动程序的时候要能保证使用的是之前的配置，而不是默认配置，在这里使用SharedPreferences是最好的选择了。
