    <p>I'm trying to create a custom ListView that displays the event's name, date, and the time it starts.</p> <p>I am able to create the ListView, however only the event's name is displayed. I've tried several experiments with the list adapter and making seperate ArrayLists for each item and that did not work. Can you show me how to get the data in the for loop in the <code>displaylist()</code> method to print out the "Event Date" and "Event Time"? The tutorial I'm following hard codes all the data which is not practical. Please follow this link for images of my app and what I hope to display (located at bottom of page): <a href="http://leobee.com/android/push/so/listview.html" rel="nofollow">see images</a></p> <pre><code>public class DataView extends ListActivity{ FileInputStream inputStream;

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
