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。
