    <p>I am reading a json file from a local drive and making it as gson. And it's working as a java application.</p> <pre><code> Gson gson = new Gson(); BufferedReader br = new BufferedReader(new FileReader("D:\\AircraftService.json")); DataObject[] obj = gson.fromJson(br, DataObject[].class); System.out.println("The object length is: " + obj.length); for(int i = 0; i&lt;obj.length ; i++ ) { System.out.println(obj[i].AC + " " + obj[i].Fleet + " " + obj[i].SubFleet); } </code></pre> <p>Using this I am trying to populate an android list </p> <pre><code>public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.listplaceholder); ListView lv= (ListView)findViewById(R.id.list); Gson gson = new Gson(); BufferedReader br = new BufferedReader(new FileReader("D:\\AircraftService.json")); DataObject[] obj = gson.fromJson(br, DataObject[].class); List&lt;HashMap&lt;String, String&gt;&gt; fillMaps = new ArrayList&lt;HashMap&lt;String, String&gt;&gt;(); for(int i=0 ; i&lt;obj.length ; i++){ HashMap&lt;String, String&gt; map = new HashMap&lt;String, String&gt;(); map.put("AC", obj[i].AC); map.put("Fleet", obj[i].Fleet ); map.put("SubFleet", obj[i].SubFleet ); fillMaps.add(map); } SimpleAdapter adapter = new SimpleAdapter(this, fillMaps, R.layout.main, new String[] {"AC", "Fleet"}, new int[] {R.id.ac, R.id.fleet}); lv.setAdapter(adapter); } </code></pre> <p>It's not able to populate the obj.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
