308 PointsWhat is wrong with my code for this question? Fairly sure I'm right lol
Question is: Now create a new instance of this Fragment in MainActivity, and then add it to MainActivity's layout by using the placeholder ViewGroup (R.id.placeholder).
My code: Fragment NewsFragment = new Fragment(); FragmentManager fragmentManager = getFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); fragmentTransaction.add(R.id.placeholder, NewsFragment); fragmentTransaction.commit();
What it's tell me: Bummer! Don't forget to include your NewsFragment instance as the second argument to the 'add' method.
What's wrong with my answer? I'm honestly stuck.
public class NewsFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return null;
}
}
public class MainActivity extends AppCompatActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
