Android: DatePicker and DatePicker Dialog

Question

I have this code here on the options menu

Dialog dialog = new Dialog(ScheduleActivity.this);
dialog.setTitle("Add Event");
dialog.setContentView(R.layout.add_even_on);
Button datePicker = (Button) dialog.findViewById(R.id.datePicker);
final DialogFragment dateFrag = new MyDatePicker();
    datePicker.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                dateFrag.show(getSupportFragmentManager(), "datePicker");               
            }
        });
dialog.show();

when, say "Add Event" on the option menu is clicked, a Dialog appears, with a button that shows a DatePickerDialog and beside it is a TextView that reflects the date chosen in the DatePickerDialog, here is the class I got from Androids Developer on how to use the DatePickerDialog.

class MyDatePicker extends DialogFragment implements DatePickerDialog.OnDateSetListener {
 int pYear;
 int pDay;
 int pMonth;

@Override
  public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the current date as the default date in the picker
    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);

    // Create a new instance of DatePickerDialog and return it
    return new DatePickerDialog(getActivity(), this, year, month, day);
  }

  public void onDateSet(DatePicker view, int year, int month, int day) {
    pYear = year;
    pDay = day;
    pMonth = month;
  }
}

So my problem is that how do i get the Value in milleseconds when i click "Set" on the DatePickerDialog which in turn automatically closes it, and returns to my Dialog which contains the button which open the DatePickerDialog and a Textview which reflects watever date is chosen the DatePickerDialog... i wont show the one i chose inside the DatePickerDialog...

Here is a picture of what i mean,

So when i click on the Pick Date Button a DatePickerDialog box appears as seen on the next picture

and when i click set, i wanted to take into account the value in millseconds from that DatePickerDialog

Old dialogs are deprecated. Implements fragments:

Migrate your Activity to Fragment Activity:

public class YourActivity extends FragmentActivity 

Create Fragment Dialog:

public class TimePickerFragment extends DialogFragment {

    private OnDateSetListener listener;

    public TimePickerFragment(OnDateSetListener listener) {
        this.listener=listener;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current time as the default values for the picker
        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);

        // Create a new instance of TimePickerDialog and return it
        return new DatePickerDialog(getActivity(), listener, year,month,day);
    }

}

Implements interface (package: import android.app.DatePickerDialog.OnDateSetListener):

public class YourActivity extends FragmentActivity implements OnDateSetListener{

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

    }

}

Add showDialog function:

public class YourActivity extends FragmentActivity implements OnDateSetListener{

    showDateDialog(){

        FragmentManager fm = getSupportFragmentManager();
        TimePickerFragment newFragment = new TimePickerFragment(this);
        newFragment.show(fm, "date_picker");

    }

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

    }

}
