Android : Scroll arrow in Navigation Tabs of actionbar

Thank you everyone in advance for spending your valuable time by reading this post.

I have chosen action bar with navigation tabs for fulfilling my app requirement.If I set three tabs in navigation mode, window width is good enough to show all the tabs.When I add more than 3, say 5, tabs are visible and I can access it by scrolling horizontally.Even though, tabs are visible only on scrolling to right and user may not aware that more tabs are available. Is it possible to add arrow images in Navigation TabView if more tabs were available? I believe navigation tabs are shown in stack view of actionbar.Is there some way to add custom view in stacked layout of actionbar?

Please suggest me some ideas.Have a nice day.
