Android doesn't have a ready-made adapter to populate a <code>ListView</code> with a JSON array, like it does for populating a <code>ListView</code> with database records. I recommend getting comfortable with populating a Java data structure of your choice with the JSON data, and getting comfortable with working with <code>ListViews</code>, populating them from different collections, with different custom rows. Here's a simple example of populating a <code>List</code> from a JSON array, and then using the <code>List</code> to populate a <code>ListView</code>. <pre><code>import java.util.ArrayList; import java.util.List; import org.json.JSONArray; import android.app.Activity; import android.os.Bundle; import android.widget.ArrayAdapter; import android.widget.ListView; public class Main extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); try { String jsonInput = "[\"one\",\"two\",\"three\",\"four\",\"five\",\"six\",\"seven\",\"eight\",\"nine\",\"ten\"]"; JSONArray jsonArray = new JSONArray(jsonInput); int length = jsonArray.length(); List<String> listContents = new ArrayList<String>(length); for (int i = 0; i < length; i++) { listContents.add(jsonArray.getString(i)); } ListView myListView = (ListView) findViewById(R.id.my_list); myListView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listContents)); } catch (Exception e) { // this is just an example } } } </code></pre>

Guidance

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.
