Using findViewById inside a Fragment

Maven Published at Dev

Maven

I am creating a new Tab interface and for every tab I have functionality like:

public class ClassViewFragment extends Fragment {
    ListView classListView = null;

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

        View rootView = inflater.inflate(R.layout.class_view, container, false);

        classListView = (ListView) findViewById(R.id.classList);

        return rootView;
    }
}

But I am getting cannot resolve method findViewById also at another place I am also unable to use runOnUiThread and getting Error:(88, 29) error: cannot find symbol method runOnUiThread(<anonymous Runnable>)

I understand these will work fine if my class was extended from Activity but it’s a tab fragment so how can I use this funcitons?

you need

classListView = (ListView) rootView.findViewById(R.id.classList);

as that is the view you are concerned with

to get runOnUiThred you need to do getActivity().runOnUiThread
