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：
