I\'m using the google example to insert a datepicker inside my app using a dialogfragment

The problem can also be solved without moving the onDateSet method to the parent activity. You just have to tell the DatePickerFragment where to search for the view:

public class DatePickerFragment extends DialogFragment implements
    DatePickerDialog.OnDateSetListener {

    @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) {
        // do some stuff for example write on log and update TextField on activity
        Log.w("DatePicker","Date = " + year);
        ((TextView) getActivity().findViewById(R.id.tf_date)).setText("Date = " + year);
    }
}

I also changed the target of the cast from EditText to TextView. This way, you can reuse your implementation for different kinds of views, not only for an EditText.
