  <p>My question is how to combine the two different lists together in an activity.  Thanks.</p>
  
  <pre><code>// Load from file "cities.json" first time
  if (mAdapter == null) {
      List&lt;City&gt; cities = null;
      try {
          cities = loadCities();
      } catch (IOException e) {
          e.printStackTrace();
      }
  
      // This is the GridView adapter
      ListAdapter = new CityAdapter(this);
      ListAdapter.setData(cities);
  }
  </code></pre>
