    <p>So I believe I have resolved the main problem I was facing.</p> <p>I believe the problem I was having was that my view was not representing the state of the ListView. In lamens; I thought a checkbox was needed to set whether a list item was checked or not (this is the web developer in me). However, the ListView maintains its own state of whats checked and whats not, regardless if you have a view (CheckBox) to represent that or not.</p> <p>layout/list_item.xml</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/linearLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" &gt; &lt;ProgressBar android:id="@+id/progressBar1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="5dip" /&gt; &lt;LinearLayout android:id="@+id/linearLayout2" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_weight="1" android:orientation="vertical" &gt; &lt;TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Line 1" android:textAppearance="?android:attr/textAppearanceMedium" /&gt; &lt;TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Line 2" /&gt; &lt;/LinearLayout&gt; &lt;CheckBox android:id="@+id/checkBox1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:clickable="false" android:focusable="false" android:visibility="gone" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>menu/menu.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;menu xmlns:android="http://schemas.android.com/apk/res/android" &gt; &lt;item android:id="@+id/edit_menu_item" android:title="KAMEHAMEHA!!!!!"/&gt;

</code></pre> <p>That's it. Kind of obvious once you know how it all works. Too bad it took me this long to figure out. Sometimes I feel the android programming is a bit too complex at times.</p> <p>The only problem I have now is that the ListView items are always redrawn when a list item is clicked. This is wreaking havoc on my list items which contain asynchronously loaded images from file. Hopefully when I beef up the performance on that portion of my code, this will disappear.</p>

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.
