DatePickerDialog (Calendar Mode) (Default)

int selectedYear = 2000;
int selectedMonth = 5;
int selectedDayOfMonth = 10;

// Date Select Listener.
DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener() {

    @Override
    public void onDateSet(DatePicker view, int year,
                          int monthOfYear, int dayOfMonth) {

        editTextDate.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);
    }
};

// Create DatePickerDialog (Spinner Mode):
DatePickerDialog datePickerDialog = new DatePickerDialog(this,
            dateSetListener, selectedYear, selectedMonth, selectedDayOfMonth);

// Show
datePickerDialog.show();

DatePickerDialog (Spinner Mode)

int selectedYear = 2000;
int selectedMonth = 5;
int selectedDayOfMonth = 10;

// Date Select Listener.
DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener() {

    @Override
    public void onDateSet(DatePicker view, int year,
                          int monthOfYear, int dayOfMonth) {

        editTextDate.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);
    }
};

// Create DatePickerDialog (Spinner Mode):
DatePickerDialog datePickerDialog = new DatePickerDialog(this,
            android.R.style.Theme_Holo_Light_Dialog_NoActionBar,
            dateSetListener, selectedYear, selectedMonth, selectedDayOfMonth);

// Show
datePickerDialog.show();
