in order for you to make the selector work , set the selector as the background and not the style. in which case you could have something like this:
<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/glow_effect" android:state_pressed="true"/>
<item android:drawable="@drawable/actual_image_here"/>
<item android:drawable="@drawable/actual_image_here"/>
the above line would display the image that you want and the selector work when you press it.
