How can i parse response to get images corresponding to items. Following is the code, Any one who know how to do this kindly help me it would be very useful.</p> <p>Note: images and items are NOT Fixed</p> <pre><code>public class AndroidJSONParsingActivity extends ListActivity { // url to make request private static String url = "website/?JSON=get_recent_post";

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.
