Scrollable TabWidget in Android

I practiced the Tab Layout Tutorial by

http://developer.android.com/resources/tutorials/views/hello-tabwidget.html

and realized that I need to scroll the TabWidget. After Goofling "android scroll tabwidget",

I could not successfully paste the xml here, so I use "[" and "]" instead of "<" and ">"
 

Originally is

                    [TabWidget

            android:id="@android:id/tabs"

            android:layout_width="fill_parent"

            android:layout_height="wrap_content" /]

Now is


[HorizontalScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"]    
                    [TabWidget
        android:orientation="horizontal"
           android:id="@android:id/tabs"
           android:layout_width="fill_parent"
           android:layout_height="wrap_content" /]
        [/HorizontalScrollView]
