一、實現動態輸入日期和時間
* DataPicker(日歷選擇器)
* DataPicker對象以init()方法指定DatePicker初始的年月日及OnDateChangedListener事件
* Timepicker(時間選擇器)
* Timepicker對象直接以setOnTimeChangedListener()事件處理時間改變時稱需要做的操作
*
* 二、動態輸入日期和時間的對話框
* DataPickerDialog
*
* TimePickerDialog
*
* 三、監聽器
* OnDateChangedListener
* 當用戶更改了DataPicker中的年、月、日將觸發OnDateChangedListener監聽器的onDateChange()事件
*
* OntimeChangedListener
* 當用戶更改了TimePicker中的時、分、秒將觸發OnTimeChangedListener監聽器的onTimeChange()事件
*
* OnDateSetListener
* 當用戶更改了DataPickerDialog中的年、月、日將觸發OnDateSetListener監聽器的onDateSet()事件
*
* OnTimeSetListener
* 當用戶更改了TimePickerDialog中的時、分、秒將觸發OnTimeSetListener監聽器的onTimeSet()事件
