Prevent users from picking past dates using DatePickerDialog

Question

This question describes how to do this using the DatePicker widget, but I have nothing of the kind.

I have:

@Override protected Dialog onCreateDialog(int id) { switch (id) { case DATE_DIALOG_ID: return new DatePickerDialog(this, mDateSetListener, mYear1, mMonth1, mDay1); case DATE_DIALOG_ID_2: return new DatePickerDialog(this, mDateSetListener2, mYear2, mMonth2, mDay2); case DATE_DIALOG_ID_3: return new DatePickerDialog(this, mDateSetListener3, mYear3, mMonth3, mDay3); } return null; } protected void onPrepareDialog(int id, Dialog dialog) { switch (id) { case DATE_DIALOG_ID: ((DatePickerDialog) dialog).updateDate(mYear1, mMonth1, mDay1); break; case DATE_DIALOG_ID_2: ((DatePickerDialog) dialog).updateDate(mYear2, mMonth2, mDay2); break; case DATE_DIALOG_ID_3: ((DatePickerDialog) dialog).updateDate(mYear3, mMonth3, mDay3); break; } } 

and then three DatePickerDialog.OnDateSetListener () s

There is no setMax () or setMin () in these DatePickerDialogs.

Thanks in advance.

Answer 1

Just follow your own DatePickerDialog, which will change the date to a permitted date if the user tries to change it below the minimum date.

A split version of the one I'm using:

 public class MyDatePickerDialog extends DatePickerDialog{ private Date maxDate; private Date minDate; public MyDatePickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) { super(context, callBack, year, monthOfYear, dayOfMonth); init(year, monthOfYear, dayOfMonth); } public MyDatePickerDialog(Context context, int theme, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) { super(context, theme, callBack, year, monthOfYear, dayOfMonth); init(year, monthOfYear, dayOfMonth); } private void init(int year, int monthOfYear, int dayOfMonth){ Calendar cal = Calendar.getInstance(); cal.set(1970, Calendar.JANUARY, 1); minDate = cal.getTime(); cal.set(3000, Calendar.JANUARY, 1); maxDate = cal.getTime(); cal.set(year, monthOfYear, dayOfMonth); } public void onDateChanged (final DatePicker view, int year, int month, int day){ Calendar cal = Calendar.getInstance(); cal.set(year, month, day); Date currentDate = cal.getTime(); final Calendar resetCal = cal; if(!minDate.before(currentDate) ){ cal.setTime(minDate); view.updateDate(resetCal.get(Calendar.YEAR), resetCal.get(Calendar.MONTH), resetCal.get(Calendar.DAY_OF_MONTH)); }else if(maxDate.before(currentDate)){ cal.setTime(maxDate); view.updateDate(resetCal.get(Calendar.YEAR), resetCal.get(Calendar.MONTH), resetCal.get(Calendar.DAY_OF_MONTH)); } } public void setMaxDate(Date date){ this.maxDate = date; } public void setMinDate(Date date){ this.minDate = date; } 

}

Answer 2

my first answer. Hope everything works. I have the same problem with a dumper built into affectiveness. Based on this answer, I got this solution, but only for the maximum date.

Works fine in the emulator also for ICS.

 // Get the Date for INIT Calendar c = Calendar.getInstance(); int INIT_JAHR = c.get(Calendar.YEAR); int INIT_MONAT = c.get(Calendar.MONTH); int INIT_TAG = c.get(Calendar.DAY_OF_MONTH); this.dp_quellen_datum.init(INIT_JAHR, INIT_MONAT, INIT_TAG, new DatePicker.OnDateChangedListener() { public void onDateChanged(DatePicker datePicker, int year, int monthOfYear, int dayOfMonth) { // TODO Auto-generated method sub Calendar cal = Calendar.getInstance(); Calendar maxCal = Calendar.getInstance(); // Actual date from datepicker cal.set(year, monthOfYear, dayOfMonth); // maximum Date in my Case today maxCal.set(maxCal.get(Calendar.YEAR), maxCal.get(Calendar.MONTH), maxCal.get(Calendar.DAY_OF_MONTH)); Log.d("MAX -> Aktuell", maxCal.getTime() + "-->" + cal.getTime() + "===>" + maxCal.getTime() .before(cal.getTime())); // Set datepicker to today if selected date in the feature final Calendar resetCal = cal; // <- Don't tested if this line is needed if (maxCal.getTime().before(cal.getTime()) == true) { cal.setTime(maxCal.getTime()); Log.d("Anpassen", "AKTIV"); datePicker.updateDate( resetCal.get(Calendar.YEAR), resetCal.get(Calendar.MONTH), resetCal.get(Calendar.DAY_OF_MONTH)); } } });
