When a user clicks on a news story, a new Fragment should be displayed. Start by creating an interface in NewsFragment to serve as the listener. Name it 'NewsListener', and give it a method named 'onNewsItemSelected' which takes in an int and returns nothing.
public class NewsFragment extends Fragment {
public interface OnNewsItemSelectedInterface {
void onNewsItemSelected(int index);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
OnNewsItemSelectedInterface NewsListener = (OnNewsItemSelectedInterface) getActivity();
View view = inflater.inflate(R.layout.fragment_news, container, false);
return view;
}
}
public class MainActivity extends AppCompatActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
NewsFragment newsFragment = new NewsFragment();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.placeholder, newsFragment);
fragmentTransaction.commit();
}
}
