                    LayoutInflater l = (LayoutInflater)getContext().getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
                    convertView = (View)l.inflate(R.layout.contact_layout, parent, false);

        completionView.setAdapter(adapter);

        if (savedInstanceState == null) {
            //completionView.setPrefix("To: ");
            //completionView.addObject(people[0]);
            //completionView.addObject(people[1]);
        }

    }
