내 응용 프로그램에서 날짜 선택기를 사용하여 날짜를 설정하고 싶습니다. 날짜 선택기 최대 날짜를 시스템 날짜에 따라 오늘 날짜로 설정하고 싶습니다. 날짜 선택기 최대 날짜를 오늘 날짜로 설정하는 방법을 모르겠습니다. 누구나 알 수 있습니까? 이 문제를 해결하기 위해.
내 날짜 선택기 코딩은 다음과 같습니다.
private int pYear;
private int pMonth;
private int pDay;
static final int DATE_DIALOG_ID = 0;
final Calendar c = Calendar.getInstance();
pYear = c.get(Calendar.YEAR);
pMonth = c.get(Calendar.MONTH);
pDay = c.get(Calendar.DAY_OF_MONTH);
// Date picker
public Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
DatePickerDialog.OnDateSetListener pDateSetListener = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
pYear = year;
pMonth = monthOfYear;
pDay = dayOfMonth;
e_dob.setText(new StringBuilder()
// to set date in editext
.append(pDay).append("/").append(pMonth + 1)
.append("/").append(pYear).append(" "));
}
};
return new DatePickerDialog(this, pDateSetListener, pYear, pMonth,
pDay);
}
return null;
}답변
사용 setMaxDate().
예를 들어 return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay)다음과 같이 문을 교체 합니다.
DatePickerDialog dialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
dialog.getDatePicker().setMaxDate(new Date().getTime());
return dialog;답변
오늘 날짜 (& 시간)를 가져 와서 최대 날짜로 적용하십시오.
Calendar c = Calendar.getInstance();
c.set(2017, 0, 1);//Year,Mounth -1,Day
your_date_picker.setMaxDate(c.getTimeInMillis());또한 우리는 이것을 할 수 있습니다 (System.currentTimeMillis () 대 Calendar 메서드에 대한 이 Stackoverflow 답변 확인 )
long now = System.currentTimeMillis() - 1000;
dp_time.setMinDate(now);
dp_time.setMaxDate(now+(1000*60*60*24*7)); //After 7 Days from Now답변
이 줄을 바꿀 수 있습니다.
return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);그들에 의해 :
DatePickerDialog dpDialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
DatePicker datePicker = dpDialog.getDatePicker();
Calendar calendar = Calendar.getInstance();//get the current day
datePicker.setMaxDate(calendar.getTimeInMillis());//set the current day as the max date
return dpDialog;답변
이 시도
너무 많은 솔루션을 시도했지만 둘 다 작동하지 않았습니다. 반나절을 낭비한 후 마침내 솔루션을 만들었습니다.
이 코드는 최소 및 최대 날짜, 월 및 연도가있는 DatePickerDialog를 표시합니다.
final Calendar calendar = Calendar.getInstance();
DatePickerDialog dialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker arg0, int year, int month, int day_of_month) {
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, (month+1));
calendar.set(Calendar.DAY_OF_MONTH, day_of_month);
String myFormat = "dd/MM/yyyy";
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.getDefault());
your_edittext.setText(sdf.format(calendar.getTime()));
}
},calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
dialog.getDatePicker().setMinDate(calendar.getTimeInMillis());// TODO: used to hide previous date,month and year
calendar.add(Calendar.YEAR, 0);
dialog.getDatePicker().setMaxDate(calendar.getTimeInMillis());// TODO: used to hide future date,month and year
dialog.show();출력 :-

이 코드를 메인 메소드에서 직접 사용하면 도움이되기를 바랍니다.
@RequiresApi(api = Build.VERSION_CODES.N)
public DatePickerDialog datePickerDialog_db()
{
DatePickerDialog pickerDialog = new DatePickerDialog(getApplicationContext(),your view, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH));
pickerDialog.getDatePicker().setMaxDate(Calendar.getInstance().getTimeInMillis());
pickerDialog.show();
return null;

EightFoldsDatePickerDialog.java를 프로젝트에 복사하십시오.
EightFoldsDatePickerDialog datePickerDialog=new EightFoldsDatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
//Do something with date
Toast.makeText(this, "Year "+year+" month "+month+" day "+dayOfMonth, Toast.LENGTH_SHORT).show();
}
},year,month,day); // give any year , month , day values, this will be opened by default in dialog
datePickerDialog.setMinDate(2017,8,7); //arguments are year , month , date (use for setting custom min date)
datePickerDialog.setMaxDate(2017,8,25); //arguments are year , month , date (use for setting custom max date)
// datePickerDialog.setTodayAsMinDate(); // sets today's date as min date
// datePickerDialog.setTodayAsMaxDate(); // sets today's date as max date
datePickerDialog.show();결과
