How to remove the border for Share button in Action Bar?

Have a look at the picture

enter image description here

This is how Share button looks like in action bar.

Here's the code I use in menu xml file:

   <item
        android:id="@+id/menu_item_share"
        android:showAsAction="ifRoom"
        android:title="Share"
        android:actionProviderClass=
            "android.widget.ShareActionProvider" />

Is it possible to remove that border or change its color?

Solution

You need to use custom background.
