You can add this in Android Studio, use Right click on project structure -> New -> Drawable resource file. It should look like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_enabled="false" 
        android:drawable="@drawable/cell_top_selected" />
    <item android:drawable="@drawable/cell_top" />
</selector>

You can try this also as a selector

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- pressed -->
    <item android:drawable="@drawable/button_1_selected" android:state_pressed="true"/>
    <!-- focused -->
    <item android:drawable="@drawable/button_1_normal" android:state_focused="true"/>
    <!-- default -->
    <item android:drawable="@drawable/button_1_normal"/>

</selector>
