DatePickerDialog\TimePickerDialog日期时间选择器

相应的知识：

布局有DatePicker和TimePicker

和可视的txetview

TimePicker 是直接实现

DatePicker 是以Init（）方法来指定year，moth，day moth的计算

//获取Calendar对象再用他对象获取时间

calendar=Calendar.getInstance();

int year = calendar.get(Calendar.YEAR);

int month=calendar.get(Calendar.MONTH);

int day=calendar.get(Calendar.DAY_OF_MONTH);

int hour=calendar.get(Calendar.HOUR_OF_DAY);

int minute=calendar.get(Calendar.MINUTE);

//为DatePicker 初始化日期

date_picker.init(year, month, day, new OnDateChangedListener() {

//监听日期的改变

@Override

public void onDateChanged(DatePicker view, int year, int monthOfYear,

int dayOfMonth) {

//Toast.makeText(MainActivity.this, "现在时间："+year+"-"+(monthOfYear+1)+"-"+dayOfMonth, 0).show();

tv_date.setText("现在日期："+year+"-"+(monthOfYear+1)+"-"+dayOfMonth);

}

});

//设置时间为24小时制

time_picker.setIs24HourView(true);

time_picker.setOnTimeChangedListener(new OnTimeChangedListener() {

@Override

public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {

// TODO Auto-generated method stub

tv_time.setText("现在时间："+hourOfDay+":"+minute);

}

});

以对话框的形式显示：
