    <p>I have a drawable selector as a background for each item in a <code>ListView</code> to highlight the selected row. Eveything works fine in Ice Cream Sandwich, but doesn't seem to work in Jelly Bean. Can't find any documentation saying what changes could have caused it to stop working and what I need to do to fix it.</p> <p>By not working, I mean when I click on a row in the <code>ListView</code> the item's background color isn't turning the <code>@color/blue</code> color, but it does in ICS.</p> <p>This is the selector code I'm using (listing_selector.xml):</p> <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android" &gt; &lt;item android:state_focused="true" android:drawable="@color/blue" /&gt; &lt;item android:state_pressed="true" android:drawable="@color/blue" /&gt; &lt;item android:state_activated="true" android:drawable="@color/blue_selected" /&gt; &lt;item android:state_selected="true" android:drawable="@color/blue_selected" /&gt; &lt;item android:drawable="@android:color/transparent" /&gt; &lt;/selector&gt; </code></pre> <p>This is the layout of the <code>ListView</code> item:</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="horizontal" android:background="@color/listing_selector" &gt; &lt;TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>This the blue color resource:</p> <pre><code>&lt;resources&gt; &lt;color name="blue"&gt;#ff33b5e5&lt;/color&gt; &lt;/resources&gt; </code></pre> <p><strong>UPDATE 1:</strong></p> <p>Tried moving the selector from the <code>color</code> folder to the <code>drawable</code> folder and updating the code to this:</p> <pre><code>android:background="@drawable/listing_selector" </code></pre> <p><strong>UPDATE 2:</strong></p> <p>Also, on the <code>ListView</code>, tried adding this:</p> <pre><code> &lt;ListView android:id="@android:id/list" android:layout_width="wrap_content" android:layout_height="fill_parent" android:listSelector="@drawable/listing_selector" /&gt; </code></pre> <p><strong>UPDATE 3:</strong></p> <p>I thought it might be something in my code, but I removed all the code from <code>onListItemClick</code> of the <code>ListView</code> and still the <code>selector</code> isn't working.</p> <p><strong>UPDATE 4:</strong></p> <p>I've narrowed it down to <code>state_selected</code> or <code>state_activated</code> not working as, <code>state_pressed</code> seems to be working</p> <p><strong>UPDATE 5:</strong></p> <p>I think I was mistaken. I don't think the selector is being recognized, at all. I was confusing the built-in <code>ListView</code> highlighting as my selector. I'm now wondering if it has something to do with the way my project is setup. I have the selector in a Library Class. Maybe something changed with that from ICS to JB, however moving the selector to my app's project didn't seem to fix it.</p> <p><strong>UPDATE 6:</strong></p> <p>Ok, after some more hair pulling, I've narrowed it down, again, to either <code>state_selected</code> or <code>state_activated</code> not being recognized, as changing the color for <code>state_pressed</code> does work, which means my selector is being recognized. From the comments in seems to be something with my app specifically as others have been able to get selectors working with Jelly Bean.</p> <p>Though something else that is interesting is that changing the <code>drawable</code> value for the default state is not recognized. Where I have <code>color/transparent</code>, I would think changing that to a color would cause the listing to change to that color, but it doesn't.</p> <p>Also, this isn't working in ICS either.</p> <p><strong>UPDATE 7:</strong></p> <p>After even more hair pulling, I've discovered that long-pressing on a menu item results in that item's color being changed. Just clicking on an item still does not work. Not even sure what the means.</p> <p>** Final Update:**</p> <p>I give up, I removed the selector and am just refreshing the <code>ListView</code> on click and remembering the position clicked and highlighting it from code. Not ideal, but not worth the effort to try to fix.</p>

    1. COWhen you tried your UPDATE 2, did you remove the android:background from your list item. I use android:listSelector for the list, and then no android:background is defined for the list item; and everything works for me. Also, I'm not sure if its related but I also have android:cacheColorHint="@null".

    2. CO@Chris Yea, tried that didn't work either. I added a new update (#5). I'm wondering if the issue is with the way I have my project setup?

    3. COProject setup should be unrelated to this issue assuming you have your android dependencies showing.... which eclipse basically forces you to do. Tip on the drawable vs color thing, use android:color for xml selectors in res/color,and android:drawable for xml selectors in res/drawable. For what you have there's probably no reason to use it as a drawable rather than a color. And colors implicitly have full opacity, so #ff33b5e5 is the same as #33b5e5

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.
