Android ListView in Navigation Drawer Layout

Question

I tried to create a ListView populated with some strings that I read from an XML file a put in an ArrayList structure. I just want to show them as a list on screen. When my code reach this instruction:

MainList.setAdapter(itemsAdapter);

It just crash and I cannot understand why ... any idea, please?

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<ListView
 android:id="@+id/data_list"
 android:layout_width="match_parent"
 android:layout_height="match_parent">
</ListView>

</RelativeLayout>


public class HomeFragment extends Fragment {
    Context ct;

    public HomeFragment(Context c){
     ct=c;  
    }



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

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


      ArrayList<Zone> zones = new ArrayList<Zone>();



      try{
        MY CODE
      }catch(Exception e){

      }

      ArrayList<String> items = new ArrayList<String>();

      for (Zone zn : zones){items.add(zn.name);}

      ArrayAdapter<String> itemsAdapter = 
              new ArrayAdapter<String>(getActivity(), R.layout.fragment_home,items);

      ListView MainList = (ListView)rootView.findViewById(R.id.data_list);
      MainList.setAdapter(itemsAdapter);

      return rootView;
    }
}

* EDIT 2 *

Can I give different properties to the many textview that I put in my listview?

i.e. one textview with certain background property, another one with some particular font ... even some different behavior on click event?

You need to specify an id for your ArrayAdapter.

This question has been asked before, see this link: "ArrayAdapter requires the resource ID to be a TextView" xml problems

You should have something like:

ArrayAdapter(Context context, int resource, int textViewResourceId, T[] objects)

More info: http://developer.android.com/reference/android/widget/ArrayAdapter.html

where your ID should be a TextView defined in your R.layout.fragment_home since it's your resource

You need to specify your text view id and by mistake you give a relative layout id to textview, give a specific id to textview ArrayAdapter requires the resource ID to be a TextView
