Proper usage of twoLineListItem Android

Question

I am new to development on android and trying to create a list that has a bold header
and a smaller description for each item. Like the one shown here (sorry can\'t post

In the case of an Array of Objects, you just have to implement your own adapter. It can work for a TwoLineListItem or any other custom layout.

For example, if I have a list of items of the following type :

public class ProfileItem {
    public String host, name, tag;

    public ProfileItem(String host, String name, String tag) {
        this.host = host;
        this.name = name;
        this.tag = tag;
    }

    @Override
    public String toString() {
        return name+"#"+tag;
    }
}

Then I create the following adapter :

public class ProfileItemAdapter extends ArrayAdapter {

private Context context;
private int layoutResourceId;   
private List objects = null;

public ProfileItemAdapter(Context context, int layoutResourceId, List objects) {
    super(context, layoutResourceId, objects);
    this.context = context;
    this.layoutResourceId = layoutResourceId;
    this.objects = objects;
}

public View getView(int position, View convertView, ViewGroup parent)  {
    View v = convertView;
    if(v == null)
    {
        LayoutInflater inflater = ((Activity)context).getLayoutInflater();
        v = inflater.inflate(layoutResourceId, parent, false);
    }

    ProfileItem item = objects.get(position);
    TextView titletext = (TextView)v.findViewById(android.R.id.text1);
    titletext.setText(item.toString());
    TextView mainsmalltext = (TextView)v.findViewById(android.R.id.text2);
    mainsmalltext.setText(item.host);
    return v;
}

}

Then everything is in place, in my activity (or fragment), I just have to set this adapter in the onCreate method :

setListAdapter(new ProfileItemAdapter(getActivity(),
            android.R.layout.two_line_list_item, // or my own custom layout 
            ProfileListContent.ITEMS));
