16,570 PointsDon't really get this question.
This is in reference to part 2 of this exercise.
For 1. I copied and pasted ListFragment fragment = new ListFragment(); FragmentManager fragmentManager = getFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); fragmentTransaction.add(R.id.placeHolder, fragment); fragmentTransaction.commit();
I think I did exactly what it told me to do, but the question didn't say anything about using FragmentManager(which I used). Since I don't know any other way to do this then, I don't know how to exactly answer this question.
Any help/advice would be great
public class NewsFragment extends Fragment {
@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 {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListFragment fragment = new ListFragment();
fragment.add(R.id.placeholder, fragment);
}
}

You've got an extra semicolon on an empty line in your NewsFragment
, and fragment
should be a NewsFragment
instead of a ListFragment
. Otherwise, your code looks sound.
Hope that helps!
