在Android中关于日期时间的类有TimePicker、DatePicker、TimePickerDialog、DatePickerDialog、Calendar。其中TimePickerDialog、DatePickerDialog是对话框形式。

一、TimePicker

　　查看一个在24小时或上午/下午模式下一天的时间。

1.重要方法
setCurrentMinute(Integer currentMinute)设置当前时间的分钟

　　getCurrentMinute()获取当前时间的分钟

　　setEnabled(boolean enabled)设置当前视图是否可以编辑。

　　m_TimePicker.setIs24HourView(true);设置为24小时制显示

　　setOnTimeChangedListener(TimePicker.OnTimeChangedListener onTimeChangedListener)当时间改变时调用

二、DatePicker

　　1.重要方法

　　getDayOfMonth():获取当前Day

　　getMonth():获取当前月

　　getYear()获取当前年

三、TimePickerDialog、DatePickerDialog

　　以对话框形式显示日期时间视图

四、Calendar

　　日历是设定年度日期对象和一个整数字段之间转换的抽象基类，如，月，日，小时等。

　　updateDate(int year, int monthOfYear, int dayOfMonth)：更新日期

案例定义一个布局文件timepicker.xml
