android-时间选择器和日期选择器

IT知识选择器日期选择日期选择器

笛里谁知壮士心，沙头空照征人骨。这篇文章主要讲述android-时间选择器和日期选择器相关的知识，希望能为你提供帮助。
一、实现动态输入日期和时间
* DataPicker(日历选择器)
*DataPicker对象以init()方法指定DatePicker初始的年月日及OnDateChangedListener事件
* Timepicker(时间选择器)
*Timepicker对象直接以setOnTimeChangedListener()事件处理时间改变时称需要做的操作
*
* 二、动态输入日期和时间的对话框
* DataPickerDialog
*
* TimePickerDialog
*
* 三、监听器
* OnDateChangedListener
*当用户更改了DataPicker中的年、月、日将触发OnDateChangedListener监听器的onDateChange()事件
*
* OntimeChangedListener
*当用户更改了TimePicker中的时、分、秒将触发OnTimeChangedListener监听器的onTimeChange()事件
*
* OnDateSetListener
*当用户更改了DataPickerDialog中的年、月、日将触发OnDateSetListener监听器的onDateSet()事件
*
* OnTimeSetListener
*当用户更改了TimePickerDialog中的时、分、秒将触发OnTimeSetListener监听器的onTimeSet()事件
