You can try to create a new style for your icon in action bar like this : *Add this code in your styles.xml

    <!-- style for Action Bar -->
<style name="MyActionBarTabStyle" parent="android:style/Widget.Holo.Light.ActionBarView">
    <item name="android:background">@drawable/actionbar_tab_bg</item>
    <item name="android:paddingLeft">32dp</item>
    <item name="android:paddingRight">32dp</item>
</style>

*add your style to the UI action bar .
