Start with the NewsFragment and return a View in its onCreateView method. Use the 'R.layout.fragment_news' layout id.

i have no idea how to do this

NewsFragment.java 
public class NewsFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        return null;
    }
}
MainActivity.java 
public class MainActivity extends AppCompatActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }
}

this is the first part

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

  View view = inflater.inflate(R.layout.fragment_news, container, false);
    return view;
}

this is the second part. i've also placed a shorter way to implement your fragment into your class. the way in the video is super long but my other route is the better option.

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();
}

The way below is even shorter

newListFragment = new ListFragment();

           getFragmentManager()
                   .beginTransaction()
                   .add(R.id.placeHolder,newListFragment)
                   .commit();
