7.Android开源项目WheelView的时间和地址联动选择对话框

类似WheelView的时间和地址联动选择对话框在现在App经常看到，今天小结下。

主布局界面：

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:background="#ffffff"
     android:orientation="vertical" >
