自訂Android日期時間選擇控制項DateTimePickerDialog

Android系統提供了DatePicker、TimePicker、DatePickerDialog、TimePickerDialog控制項用於日期和時間的選擇和設定，但是它們都是相對獨立的，不能方便的設定“yyyy-MM-dd HH:mm:ss”型日期時間，下面是使用這幾種組件自訂的一個日期時間選擇控制項DateTimePickerDialog，可以方便的設定“yyyy-MM-dd HH:mm:ss”型日期時間，“yyyy-MM-dd”型日期和“HH:mm:ss”型時間，

代碼實現：

設定之後日期時間控制項效果如下
