How can I theme the list seletor in a ContextMenu? For ListViews I used the way described here: http://brainflush.wordpress.com/2009/03/15/understanding-android-themes-and-styles/ So I assigned the created style to my theme like this: <style name="Theme...." parent="@android:style/Theme.Light"> <item name="android:listViewStyle">@style/ListView</item> </style> ialexander Try Override context menu colors in Android and see if it helps.
