Question

I have created an interface called NewsListener in the NewsFragment class. I get error when i implement this interface in the MainActivity ...the error states that i can override method onNewsItemSelected(int) method..MainActivity does not override onNewsItemSelected.

Please help.

NewsFragment.java

public class NewsFragment extends Fragment {

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

MainActivity.java

public class MainActivity extends AppCompatActivity implements NewsFragment.NewsListener {
    @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();
    }
}

In order to implement the interface, you need to add an onNewsItemSelected method to MainActivity. When you implement an interface, you need to supply all of its methods.
