平时我们开发的大多数的Android、iOS的APP,它们的风格都是拟物化设计。如今Android 4.X、iOS 7、WP8采用的是扁平化设计,可以看出扁平化设计是未来UI设计的趋势。其实扁平化设计要比拟物化设计要简单一点,扁平化设计更加的简约,给人视觉上更加舒服。

Shamoo想到在Android平台上弄一个扁平化的对话框。参考过一篇帖子,然后改了一下。

这个Demo比较简单,首先是一个dialog的布局文件,这个dialog的布局要实例化成对话框可以通过AlertDialog.Builder的setView方法,将LayoutInflater实例化的dialog布局设置对话框具体显示内容。效果图如下:
