In case you have to return a result to a Fragment, but not an Activity, here is a complete solution:

public class DatePickerDialogFragment extends DialogFragment  {

    private static final String ARGUMENT_YEAR = "ARGUMENT_YEAR";
    private static final String ARGUMENT_MONTH = "ARGUMENT_MONTH";
    private static final String ARGUMENT_DAY = "ARGUMENT_DAY";
    private DatePickerDialog.OnDateSetListener listener;

    private int year;
    private int month;
    private int dayOfMonth;

    public static DatePickerDialogFragment newInstance(final int year, final int month, final int dayOfMonth) {
        final DatePickerDialogFragment df = new DatePickerDialogFragment();
        final Bundle args = new Bundle();
        args.putInt(ARGUMENT_YEAR, year);
        args.putInt(ARGUMENT_MONTH, month);
        args.putInt(ARGUMENT_DAY, dayOfMonth);
        df.setArguments(args);
        return df;
    }

    @Override
    public void onCreate(@Nullable final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        retrieveArguments();
    }

    private void retrieveArguments() {
        final Bundle args = getArguments();
        if (args != null) {
            year = args.getInt(ARGUMENT_YEAR);
            month = args.getInt(ARGUMENT_MONTH);
            dayOfMonth = args.getInt(ARGUMENT_DAY);
        }
    }

    @Override
    public Dialog onCreateDialog(final Bundle savedInstanceState) {
        return new DatePickerDialog(getContext(), this.listener, this.year, this.month, this.dayOfMonth);
    }

    public void setListener(final DatePickerDialog.OnDateSetListener listener) {
        this.listener = listener;
    }
}

Then just use it in a Fragment or in an Activity:

final Calendar c = Calendar.getInstance();
DatePickerDialogFragment datePicker = DatePickerDialogFragment.newInstance(
        c.get(Calendar.YEAR),
        c.get(Calendar.MONTH),
        c.get(Calendar.DAY_OF_MONTH));
datePicker.setListener(this);
datePicker.show(getChildFragmentManager(), null);
