Question

Je veux désactiver les dates avant la date d'aujourd'hui dans la DatePickerDialog .Je suis nouveau dans Android s'il vous plaît me suggérer comment pourrais-je faire .Voici mon code que je l'ai écrit pour DatePickerDialog

final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() { 

      @Override 
      public void onDateSet(DatePicker view, int year, int monthOfYear, 
        int dayOfMonth) { 
       // TODO Auto-generated method stub 
        myCalendar.set(Calendar.YEAR, year); 
        myCalendar.set(Calendar.MONTH, monthOfYear); 
        myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth); 
        updateLabel(val); 
      } 
     }; 
     depart.setOnClickListener(new View.OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        // TODO Auto-generated method stub 
        new DatePickerDialog(this, date, myCalendar 
          .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), 
          myCalendar.get(Calendar.DAY_OF_MONTH)).show(); 
        val=1; 
       } 
      }); 

     returnDate.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        // TODO Auto-generated method stub 
        new DatePickerDialog(this, date, myCalendar 
          .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), 
          myCalendar.get(Calendar.DAY_OF_MONTH)).show(); 
          val=2; 
       } 
      }); 


private void updateLabel(int val) { 

     String myFormat = "dd/MM/yy"; //In which you need put here 
     SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US); 
     Log.d("Date vlue ", "==="+sdf.format(myCalendar.getTime())); 
     if(val==1) 
      depart.setText(sdf.format(myCalendar.getTime())); 
     else 
      returnDate.setText(sdf.format(myCalendar.getTime())); 

     }

Answer 2

Obtenez le DatePicker utilisé dans votre DatePickerDialog avec la méthode getDatePicker() et utilisez la méthode setMinDate(Long millis).

Passez la date minimum (en millisecondes depuis Epoch) que vous devez définir.

Alors vous pouvez faire quelque chose comme

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy"); 
Date d = sdf.parse("21/12/2012"); 
DatePicker datePicker = date.getDatePicker(); 
datePicker.setMinDate(d.getTime()); 

---

EDIT:

ok, donc quand vous créez votre DatePickerDialog, avant de le montrer, il suffit de sauvegarder à une variable, définissez la date minimale et ensuite le montrer.

DatePickerDialog dpd = new DatePickerDialog(IweenFlightSearch.this, date, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); 
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy"); 
Date d = sdf.parse("21/12/2012"); 
dpd.getDatePicker().setMinDate(d.getTime()); 
dpd.show(); 

cela devrait fonctionner.

Answer 3

Je suis la solution .Hope il aidera à quelqu'un static final int DATE_DIALOG_ID = 999;

depart.setOnClickListener(new View.OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        // TODO Auto-generated method stub 
        showDialog(DATE_DIALOG_ID); 

       } 
      }); 



protected Dialog onCreateDialog(int id) { 
     final Calendar now = Calendar.getInstance(); 

     switch (id) { 
     case DATE_DIALOG_ID: 
      // set date picker as current date 
      DatePickerDialog _date = new DatePickerDialog(this, date,myCalendar 
        .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), 
        myCalendar.get(Calendar.DAY_OF_MONTH)){ 
       @Override 
       public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) 
       { 
        if (year < now.get(Calendar.YEAR)) 

         view.updateDate(myCalendar 
           .get(Calendar.YEAR), myCalendar 
           .get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); 

        if (monthOfYear < now.get(Calendar.MONTH) && year == now.get(Calendar.YEAR)) 
         view.updateDate(myCalendar 
           .get(Calendar.YEAR), myCalendar 
           .get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); 

        if (dayOfMonth < now.get(Calendar.DAY_OF_MONTH) && year == now.get(Calendar.YEAR) && 
          monthOfYear == now.get(Calendar.MONTH)) 
         view.updateDate(myCalendar 
           .get(Calendar.YEAR), myCalendar 
           .get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)); 
         } 
      }; 
      return _date; 
     } 
     return null; 
    } 

Answer 4

Je sais qu'il est trop tard. Mais j'espère que cela aidera. Utilisez

date .getDatePicker().setMinDate(System.currentTimeMillis() - 1000); 

à la date de votre cas est DatePickerDialog

Cheers!

Answer 5

// Création d'une nouvelle instance de DatePickerDialog et le retourner

DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(), this,year,month,day); 
      datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis()); 
      return datePickerDialog;
