    <p>So here's what I did.</p> <p><strong>Edit: Over a year passed since I found out the previous answer had alot of useless code (woops) and the CAB thing can be achieved with much less effort and a cleaner code, so I took some time and updated it</strong></p> <p>The LibraryFragment ListView should be defined with choice mode "none"</p> <pre><code>&lt;ListView android:id="@android:id/list" android:layout_width="match_parent" android:layout_height="match_parent" android:choiceMode="none"/&gt;

    2. COthanks for this great post, but I have an issue on orientation change. Let's say, I selected a few items on the actionmode, then rotate the device, I am able to restore the actionbar, and set the selected items. But the highlight doesn't show up until I scroll the list off the screen and back, the highlight showed. Any idea?

    3. CO@triston how do you restore state? Make sure you call setChecked() on Adapter. In this case it should work. But if that's what you were doing and it's not working, I'm afraid I can't help you since I don't have enough free time to test these things out.

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.
