Add this theme to you spinner:

values/styles.xml

<resources> 
   <style name="MyTheme"> 
    <item name="android:spinnerStyle">@style/StandardSpinner</item>
   </style>
</resources>


<style name="StandardSpinner" parent="@android:style/Widget.Spinner">
    <item name="android:background">@drawable/spinner</item>
</style>
