TimePicker來展示時(shí)分秒

DatePicker來展示年月日

代碼實(shí)現(xiàn)

• 頁面布局的實(shí)現(xiàn)

• 功能的實(shí)現(xiàn)

  datePicker=(DatePicker) findViewById(R.id.datePicker);
        timePicker=(TimePicker) findViewById(R.id.timePicker);
        //獲取一個(gè)日歷對象
        calendar=Calendar.getInstance();
        //獲取年月日時(shí)分秒的信息
        year=calendar.get(Calendar.YEAR);
//        //它是從零開始計(jì)月份的
        month=calendar.get(Calendar.MONTH)+1;
        day=calendar.get(Calendar.DAY_OF_MONTH);
        hour=calendar.get(Calendar.HOUR_OF_DAY);
        minute=calendar.get(Calendar.MINUTE);
        setTitle(year+":"+month+":"+day+":"+hour+":"+minute);

對時(shí)間的設(shè)置進(jìn)行初始化 使用OnDateChangedListener來監(jiān)聽時(shí)間的變化進(jìn)行顯示

 //初始化操作
        datePicker.init(year, calendar.get(Calendar.MONTH), day, new DatePicker.OnDateChangedListener() {
            @Override
            public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                setTitle(year+":"+(monthOfYear+1)+":"+dayOfMonth);
            }
        });

對時(shí)分秒的設(shè)置進(jìn)行初始化 使用OnTimeChangedListener來監(jiān)聽時(shí)間的變化進(jìn)行顯示

timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
         @Override
         public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
             setTitle(hourOfDay+":"+minute);
         }
     });

我們一對話框的形式

*展示時(shí)間 使用 OnDateSetListener來監(jiān)聽時(shí)間的變化進(jìn)行顯示

        new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                setTitle(year+":"+month+":"+dayOfMonth);
            }
        },year,calendar.get(Calendar.MINUTE),day).show();

*展示時(shí)分 使用 OnTimeSetListener來監(jiān)聽時(shí)間的變化進(jìn)行顯示

  //以對話框的形式展示時(shí)分秒
        new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                setTitle(hourOfDay+":"+minute);
            }
        },hour,minute,true).show();
