如何使用 DialogFragment 做出自己的 DatePickerDialog 並將時間設定值設定在EditText元件中

自訂一個 class extends DialogFragment
public class MyDialogFragment extends DialogFragment implements OnDateSetListener{

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

String mYear = String.valueOf(year);
String mMonth = (monthOfYear+1 > 9)? (monthOfYear+1) +"" : "0" + (monthOfYear+1);
String mDay = (dayOfMonth > 9)? (dayOfMonth) +"" : "0" + (dayOfMonth);

EditText etday = (EditText)getActivity().findViewById(R.id.et_birthday);
etday.setText(mYear + mMonth + mDay);
}


@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

final Calendar c = Calendar.getInstance();
int Year = c.get(Calendar.YEAR);
int Month = c.get(Calendar.MONTH);
int Day = c.get(Calendar.DAY_OF_MONTH);
       
   return new DatePickerDialog(getActivity(), this, Year, Month, Day);
}
}

在要顯示Dialog 的 Activity 使用
MyDialogFragment myDateDialog = new MyDialogFragment();
myDateDialog.show(getFragmentManager(), "datePicker");

即可...
