使用了ZAKER到最新版本，其主界面采用windows phone的风格，感觉还蛮好看的，挺喜欢的，就模仿写了一下，实现到界面截图如下：
第一版面：
第二版面：
在实现了它到九宫格菜单，还实现了背景图片到缓慢移动效果。
首先来分析一下它到整个布局架构，我们肯定知道它必须是采用到FrameLayout布局，最下面到是背景图片视图，上面的是线性布局来装下左右两个面板，左边到是一个可以滚动的容器，右边放一个页码和四个按钮。
那么怎么实现背景图片的不断循环滚动呢？ 既然是显示图片的，那么自然离不开ImageView，所以在这里我们自定义一个MyImageView，它来继承ImageView，在它里面通过使用Handler消息处理机制+Timer计时器来控制图片的显示位置。
在这里，我使用了android.support.v4.view.ViewPager来实现可滑动到宫格菜单，自定义一个MyPagerAdapter继承PagerAdapter，在instantiateItem方法中配置显示参数。
大概原理就是这样，挺简单的，下面分享一下代码吧：
