Access FragmentActivity within Class extends by DialogFragment - android-fragmentactivity

Question

I have a class which extends by DialogFragment. I want to call a method in a class which extends by FragmentActivity within this DialogFragment.
In my FragmentActivity, i do as below to call DialogFragment.
DialogFragment dialogFragment = new MyDialogFragmentClass();
dialogFragment.show(getSupportFragmentManager(), "datePicker");
I'm using this DialogFragment to show a DatePicker. When user select date and click set button, i want to call a method in my FragmentActivity.
How can i do this ?

public class MainActivity extends FragmentActivity {
EditText mEdit;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void selectDate(View view) {
DialogFragment newFragment = new SelectDateFragment();
newFragment.show(getSupportFragmentManager(), "DatePicker");
}
public void populateSetDate(int year, int month, int day) {
mEdit = (EditText)findViewById(R.id.editText1);
mEdit.setText(month+"/"+day+"/"+year);
}
public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar calendar = Calendar.getInstance();
int yy = calendar.get(Calendar.YEAR);
int mm = calendar.get(Calendar.MONTH);
int dd = calendar.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(), this, yy, mm, dd);
}
public void onDateSet(DatePicker view, int yy, int mm, int dd) {
populateSetDate(yy, mm+1, dd);
}
}
}
