    <p>I'm trying to set a ListView background color based on the current theme attribute, but it crash every time the ListView is shown.It seems I'm doing something wrong but I can't see what...</p> <p>Here's what I'm doing:</p> <p>First, create the background color:</p> <pre><code>&lt;resources&gt; &lt;color name="userlist_background_light"&gt;#fff0f0f0&lt;/color&gt; &lt;color name="userlist_background_dark"&gt;#ff040404&lt;/color&gt; &lt;/resources&gt; </code></pre> <p>Second, create attributes for my custom themes:</p> <pre><code>&lt;resources&gt; &lt;attr name="userlist_background" format="reference|color" /&gt; &lt;/resources&gt; </code></pre> <p>Third, setting this attribute in my themes:</p> <pre><code>&lt;resources xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;style name="Light" parent="Theme.Sherlock.Light"&gt; &lt;item name="userlist_background"&gt;@color/userlist_background_light&lt;/item&gt; &lt;/style&gt; &lt;style name="Dark" parent="Theme.Sherlock"&gt; &lt;item name="userlist_background"&gt;@color/userlist_background_dark&lt;/item&gt; &lt;/style&gt; &lt;/resources&gt; </code></pre> <p>And finally, using this attribute in the ListView xml:</p> <pre><code>&lt;ListView android:id="@+id/user_bar" android:layout_width="0dip" android:layout_height="0dip" android:background="?attr/userlist_background" android:cacheColorHint="?userlist_background" android:visibility="gone" /&gt; </code></pre> <p>Even the Eclipse layout view crash. Of course, it works fine if I use a "@color/" directly in the background attribute. It even work if I use say, "?android:attr/colorBackground". </p> <p>The message error is:</p> <blockquote> <p>android.view.InflateException: Binary XML file line #8: Error inflating class android.view.ListView Caused by: android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path): TypedValue{t=0x2/d=0x7f010068 a=-1}</p> </blockquote> <p>I'm pretty sure I'm doing something wrong, as it works with android attributes, but I haven't be able to find what during my Google searches.</p> <p>I hope you'll be able to help me!</p> <p>Many thanks,</p> <p>Sébastien.</p>

    3. COI've run you code and it works flawless so there must be something else in your code. Did you try restarting Eclipse and cleaning the project?

Querying!

 
Guidance
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.

SQuiL has stopped working due to an internal error.

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