Scrollable Tabs with adjustable height of the Tabs in android

Question

I am trying to implement scrollable tabs with custom height of the tabs. I have searched a lot and found that even though ActionBar is the latest thing, it somehow doesn't support changing the height of the tab navigation bar.

I know this has probably been asked before but could someone help with me with a work around for adjusting the height of the tabs via ActionBar.

minSDKVersion = 14 targetSDKVersion = 18

Thanks. Sunny

UPDATE: veiwpager used in the xml Layout

        <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom" />
