It gives a compiler error. I don't know what to do
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;
}
}
public class MainActivity extends AppCompatActivity implements NewsFragment.NewsListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
NewsFragment fragment = new NewsFragment();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.placeholder, fragment);
fragmentTransaction.commit();
}
}

in the class line. The other is creating the methods in the class.

56,413 PointsSince you asked: the onNewsItemSelected() method needs to be created and filled in inside the MainActivity class.
