基于Android week view仿小米和iphone日历效果

前言

最近由于项目需求，要做一个仿小米日历的功能，下面显示一天的日程，header以周为单位进行滑动，github上找了很久也没有找到合适的，但找到一相近的开源项目Android-week-view，它不是我们项目所需要的效果，但是它帮我们实现的Event的添加和事件的处理，这让我们省了不少工作，Android-week-view效果如下图

废话不多说，先看看我项目中的效果

       主要包括两个核心的类，两个定义控件，上面的WeekHeaderView和下面的WeekDayView，都是继承的view，然后计算位置，将上面的week label 和下面的Day text 画上去，通过Scroller和 GestureDetector控制滑动和处理各种事件。废话不多说，直接教大家怎么用。

      首先是布局文件，大家可以通过属性去控件文字的大小，背影颜色、焦点颜色等等。

    mTv_date.setText(selectedDate.get(Calendar.YEAR)+"年"+(selectedDate.get(Calendar.MONTH)+1)+"月"); 
  } 
} 

WeekHeaderView 和WeekDayView相互监听对方的滑动才能实现联动。第一次写博客，就说这么多了，有兴趣的朋友可以去github,下载源码看看，我就不再献丑了。
