Question

I have an app with 2 tabs. Each tab has it’s respective fragment. On one of the tabs I would need to place a listview in order to receive data from stored arrays and place them as a list.

This is my code till now:

public class Frag3 extends Fragment{


    ListView lv1;
    ProgressDialog ShowProgress;
    public ArrayList<Post> PostList = new ArrayList<Post>();
    TextView tv1;
    Button button1;

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

        if (container == null) {
          return null;
       }
                View view = inflater.inflate(R.layout.tab3, container, false);
                //View tv = view.findViewById(R.id.textView1);

                View listView = view.findViewById(R.id.listView1);

               String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
                    "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
               "Linux", "OS/2" };

               ArrayAdapter<String> files = new ArrayAdapter<String>(getActivity(), 
                        android.R.layout.simple_list_item_1, 
                        values);

                lv1.setAdapter(files);

        return view;
    }

}

I’ve tried various options from different web references however none of them seemed to work. Can someone kindly guide me towards a way forward as I’m lost right now and can’t seem to understand the next steps.

Answer 1

The biggest issue is mis-matched variable names. You call out lv1 as a class member and set a list adatper against that, but you use listView to find the view. One of those needs to change.

The following change ought to help out:

lv1 = (ListView) view.findViewById(R.id.listView1);
