Dear Android experts,
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...
Here's what I'm doing:
First, create the background color:
<resources>
<color name="userlist_background_light">#fff0f0f0</color>
<color name="userlist_background_dark">#ff040404</color>
</resources>
Second, create attributes for my custom themes:
<resources>
<attr name="userlist_background" format="reference|color" />
</resources>
Third, setting this attribute in my themes:
<resources xmlns:android="http://schemas.android.com/apk/res/android";>
<style name="Light" parent="Theme.Sherlock.Light">
<item
name="userlist_background">@color/userlist_background_light</item>
</style>
<style name="Dark" parent="Theme.Sherlock">
<item
name="userlist_background">@color/userlist_background_dark</item>
</style>
</resources>
And finally, using this attribute in the ListView xml:
<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" />
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". The message error is:
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}
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.
I hope you'll be able to help me!
Many thanks,
Sébastien.
