透明UI设计

之前学习java和android时，在app市场，找到一个不错的学习软件Java学习手册、Android学习手册，挺喜欢它的那个透明的UI设计

现仿照它自己做了一个，加深自己的功力。

这个App一共用到以下几种功能：
1.GridView 九宫格（显示item）
2.ViewPage+Fragment(经典的滑动切换菜单)
3.ObjectAnimator 动画(控制page图标切换)
4.TranslateAnimation 横移动画（控制主layout的移动）
5.DrawerLayout  v4包自带抽屉功能（即侧滑菜单,但主layout不会移动），配合上面的TranslateAnimation实现主+副一起移动

主Activity代码：
