TimePickerDialog(时间选择对话框)

 创建TimePickerDialog时间选择对话框：

             1.创建一个类继承DialogFragement

           2.重写onCreateDialog()方法，返回一个TimePickerDialog对象

           3.实现TimePickerDialog的OnTimeSetListener接口来接收一个回调，当用户设置时间

DatePickerDialog(日期选择对话框)

 创建DatePickerDialog日期选择对话框：

             1.创建一个类继承DialogFragment

               2.重写onCreateDialog()方法，返回一个TimePickerDialog对象

               3.实现DatePickerDialog的OnDateSetListener接口来接收一个回调，当用户设置日期

DatePickerDialog和TimePickerDialog是Android提供的可以弹出一个日期、时间选择的对话框，我们可以在程序中通过实例化DatePickerDialog和TimePickerDialog来得到一个日期、时间对话框。这两个类都是AlertDialog的子类

我提供了一个百度的关于Picker的官方说明，可能对理解这篇文章有帮助：http://wenku.baidu.com/link?url=U77TPsl99lpf8QrGD2h6XKA6xJqzk-JseCnJhC9VmgYoWckhCZ8-3F3TzOkOZGLverjwt6JitlhW-wWMODAOQLtEpVxryaZxNlCQstOjLCK
