public class NewsFragment extends Fragment {
public interface NewsListener { void onNewsItemSelected(int index); }
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_news, container, false);
return view;
}
}
