Month name is appearing with M+number in datePicker dialog in android

Question

I am trying to display date in datePicker dialog in a format like Sep|29|2016. you can see in following image.

Expected output

unfortunately most of the time i am getting 28|M09|2016 rarely i am getting expected output. you can see in following image

current output

I have tried with following code

public Dialog onCreateDialog(Bundle savedInstanceState) {
    Calendar calendar = Calendar.getInstance();

    System.out.println(calendar.getDisplayName(Calendar.MONTH, Calendar.SHORT, Locale.US));    

    calendar.getDisplayName(Calendar.MONTH, Calendar.SHORT, Locale.US);
    int yy = calendar.get(Calendar.YEAR);
    int mm = calendar.get(Calendar.MONTH);   
    int dd = calendar.get(Calendar.DAY_OF_MONTH);      

    System.out.println("yearr==="+yy);
    System.out.println("monthh==="+mm);
    System.out.println("dayy==="+dd);



    DatePickerDialog datepickerdialog = new DatePickerDialog(getActivity(),
             this,yy,mm,dd);
    return datepickerdialog;
}

Thanks in anticipation.

Answer 1

Did you change your locale configuration? It seems that the datepickerdialog uses that format for default (English) locale when you update the locale configuration.

Instead of this

Locale locale = new Locale(countryCode);
Locale.setDefault(locale);

Do this for countries with "en" language

Locale locale = new Locale(language, countryCode);
Locale.setDefault(locale);

Sample

Locale locale = new Locale("en", "GB");

Are you expecting this?

    Button selectDate = (Button) findViewById(R.id.idButton);
    selectDate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Calendar currentDate = Calendar.getInstance(Locale.ENGLISH);
            int mYear = currentDate.get(Calendar.YEAR);
            int mMonth = currentDate.get(Calendar.MONTH);
            int mDay = currentDate.get(Calendar.DAY_OF_MONTH);

            DatePickerDialog mDatePicker = new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener() {
                public void onDateSet(DatePicker view, int selectedyear, int selectedmonth, int selectedday) {

                    GregorianCalendar gc = new GregorianCalendar();
                    gc.setFirstDayOfWeek(Calendar.MONDAY);
                    gc.set(Calendar.MONTH, view.getMonth());
                    gc.set(Calendar.DAY_OF_MONTH, view.getDayOfMonth());
                    gc.set(Calendar.YEAR, view.getYear());

                    DecimalFormat mFormat = new DecimalFormat("00");
                    String selectedDate = String.format("%s/%S/%s", gc.get(Calendar.YEAR),
                            mFormat.format(gc.get(Calendar.MONTH) + 1),
                            mFormat.format(gc.get(Calendar.DATE)));

                }
            }, mYear, mMonth, mDay);
            mDatePicker.setTitle("Select Date");
            mDatePicker.show();
        }
    });

Calendar myCalendar = Calendar.getInstance();

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();
    }

};

   edittext.setOnClickListener(new OnClickListener() {

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

      private void updateLabel() {

    String myFormat = "MM/dd/yy"; //In which you need put here
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

    edittext.setText(sdf.format(myCalendar.getTime()));
    }
