android 안드로이드 DatePickerDialog 날짜 지정하기 제한하기. (setMinDate setMaxDate)

android 안드로이드 DatePickerDialog 날짜 제한하기.

(feat. 열때 날짜 지정하기)

안드로이드 DatePickerDialog 사용 시, 날짜 선택범위를 지정하는 방법을 알아보겠습니다.

<ex>

picked Date (pickedDate) = 2018-02-12

minimum Date (minDate) = 2018-02-10

maximum Date (maxDate) = 2018-02-17

<src>

Calendar pickedDate = Calendar.getInstance();
Calendar minDate = Calendar.getInstance();
Calendar maxDate = Calendar.getInstance();

pickedDate.set(2018,2-1,12);

DatePickerDialog datePickerDialog = new DatePickerDialog(
        ThisActivity.this,
        new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                Toast.makeText(getApplicationContext(),"select date : "+ year + "-"+(month+1)+"-"+dayOfMonth,Toast.LENGTH_LONG).show();
            }
        },
       //2018-2-12
        pickedDate.get(Calendar.YEAR),
        pickedDate.get(Calendar.MONTH),
        pickedDate.get(Calendar.DATE)
);


minDate.set(2018,2-1,10);
datePickerDialog.getDatePicker().setMinDate(minDate.getTime().getTime());

maxDate.set(2018,2-1,17);
datePickerDialog.getDatePicker().setMaxDate(maxDate.getTimeInMillis());


datePickerDialog.show();

<reference>

- 보통 DB에서 date 값은 Stirng 형으로 받게 됩니다.

  이런 경우에는 String -> Date -> Calendar 로 형변환을 해주면 됩니다.

 

public static SimpleDateFormat datetimeFormat_Date = new SimpleDateFormat("yyyy-MM-dd");

String mDateStr = "2018-02-12";          // 버튼값 mDateStr 에 넣기
Calendar calendar = Calendar.getInstance();
Calendar minDate = Calendar.getInstance();
Calendar maxDate = Calendar.getInstance();

Date date = new Date();

try {
    date = BasicInfo.datetimeFormat_Date.parse(mDateStr);

} catch(Exception ex) {
    Log.d(TAG, "Exception in parsing date : " + date);
}
calendar.setTime(date);

DatePickerDialog datePickerDialog = new DatePickerDialog(
        TourDateInsertActivity.this,
        new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {

            }
        },
        calendar.get(Calendar.YEAR),
        calendar.get(Calendar.MONTH),
        calendar.get(Calendar.DAY_OF_MONTH)
);

minDate.set(2018,2-1,10);
datePickerDialog.getDatePicker().setMinDate(minDate.getTime().getTime());

maxDate.set(2018,2-1,17);
datePickerDialog.getDatePicker().setMaxDate(maxDate.getTimeInMillis());


datePickerDialog.show();
