以下代码有效..

datePickerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showDialog(0);
        }
    });

@Override
@Deprecated
protected Dialog onCreateDialog(int id) {
    return new DatePickerDialog(this, datePickerListener, year, month, day);
}

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int selectedYear,
                          int selectedMonth, int selectedDay) {
        day = selectedDay;
        month = selectedMonth;
        year = selectedYear;
        datePickerButton.setText(selectedDay + " / " + (selectedMonth + 1) + " / "
                + selectedYear);
    }
};
