android 获取datepicker的日期格式,在Android中更改DatePickerDialog日历的日期格式

我在我的代码中使用DatePickerDialog。我想知道，如何以格式dd mm yyyy更改DatePickerDialog日历的日期格式。

我的代码是： -

public static class DatePickerDialogTheme5 extends DialogFragment implements DatePickerDialog.OnDateSetListener{

@Override

public Dialog onCreateDialog(Bundle savedInstanceState){

SimpleDateFormat sdf=new SimpleDateFormat("dd MM yyyy");

Date d=new Date();

sdf.format(d);

final Calendar calendar = Calendar.getInstance();

calendar.setTime(d);

calendar.set(calendar.YEAR,d.getYear());

calendar.set(calendar.MONTH,d.getMonth());

calendar.set(calendar.DAY_OF_MONTH,d.getDay());

int year = calendar.get(Calendar.YEAR);

int month = calendar.get(Calendar.MONTH);

int day = calendar.get(Calendar.DAY_OF_MONTH);

DatePickerDialog datepickerdialog = new DatePickerDialog(getActivity(),

//AlertDialog.THEME_TRADITIONAL,this,day,month,year);

AlertDialog.THEME_DEVICE_DEFAULT_DARK,this,year,month,day);

return datepickerdialog;

}

public void onDateSet(DatePicker view, int year, int month, int day){

TextView textview = (TextView)getActivity().findViewById(R.id.textView1);

textview.setText(day + ":" + (month+1) + ":" + year);

}

}I Want to show Date Picker Dialog like this
