you can not set color resource in app:itemBackground you must have to set drawable resource in this property

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/blue" android:state_checked="true" />
    <item android:drawable="@android:color/black" android:state_checked="false" />
</selector>
