Action Bar Sherlock dropdown spinner divider
===

how can I hide dividers in action bar dropdown menu navigation? 



I tried following in styles:


	<style name="MyActionBar" parent="Widget.Sherlock.Light.ActionBar">
    	<item name="android:background">@drawable/actionbar_bg_shape</item>
    	<item name="background">@drawable/actionbar_bg_shape</item>
    	
	    <item name="android:showDividers">none</item>
	    <item name="android:divider">#00000000</item>
	    <item name="android:cacheColorHint">#00000000</item>
	    <item name="android:dividerHeight">0px</item>
	    	    
	</style>



	<style name="MyDropDownNav" parent="Widget.Sherlock.Light.Spinner.DropDown.ActionBar">
	    <item name="android:textColor">#FFFFFF</item>
	    <item name="android:background">@drawable/actionbar_bg_shape</item>
	    <item name="android:popupBackground">@drawable/actionbar_dropdown_bg_shape</item>
	    <item name="android:dropDownSelector">@drawable/dropdown_nav_selector</item>

	    <item name="android:dropDownWidth">175dp</item>
	    <item name="android:dropDownHeight">50dp</item>
	    <item name="android:showDividers">none</item>
	    <item name="android:divider">@null</item>
	    <item name="android:cacheColorHint">#00000000</item>
	    <item name="android:dividerHeight">0px</item>
	    	    
	    
	    <item name="background">@drawable/actionbar_bg_shape</item>
	</style>

	<style name="Theme.iLiga.ICS" parent="Theme.Sherlock.Light">
	   <item name="android:actionDropDownStyle">@style/MyDropDownNav</item>
       <item name="actionDropDownStyle">@style/MyDropDownNav</item>
       <item name="android:actionBarStyle">@style/MyActionBar</item>
       <item name="actionBarStyle">@style/MyActionBar</item>
       
		<item name="actionBarDivider">@drawable/icon</item>
    	<item name="android:actionBarDivider">@drawable/icon</item>

	</style>


But divider is still present in dropdown menu navigation, no effect at all. Any ideas would be really helpful.
