【转】android中的Style与Theme

Android默认情况下提供了一些实用的主题样式，比如说Theme.Dialog可以让你的Activity变成一个窗口风格，而Theme.Light则让你的整个Activity具有白色的背景，而不是黑色那么沉闷。具体使用方法很简单在Androidmanifest.xml文件中对你的Activity节点上加入些代码，如图1所示：
越来越多互联网企业都在Android平台上部署其客户端，为了提升用户体验，这些客户端都做得布局合理而且美观.......Android的Style设计就是提升用户体验的关键之一。Android上的Style分为了两个方面：
1，Theme是针对窗体级别的，改变窗体样式；
2，Style是针对窗体元素级别的，改变指定控件或者Layout的样式。

Android系统的themes.xml和style.xml(位于系统源代码frameworks\base\core\res\res\values\)包含了很多系统定义好的style，建议在里面挑个合适的，然后再继承修改。
