自定义Android日期时间选择控件DateTimePickerDialog

        Android系统提供了DatePicker、TimePicker、DatePickerDialog、TimePickerDialog控件用于日期和时间的选择和设置，但是它们都是相对独立的，不能方便的设置“yyyy-MM-dd HH:mm:ss”型日期时间，下面是使用这几种组件自定义的一个日期时间选择控件DateTimePickerDialog，可以方便的设置“yyyy-MM-dd HH:mm:ss”型日期时间，“yyyy-MM-dd”型日期和“HH:mm:ss”型时间，如下图：

代码实现：

DateTimePickerDialog.java
