TextView scroll

Hi
How do I make a TextView scroll. have Looked thru some posts but not successful. I am trying this on a widget.

<TextView
android:id="@+id/widg_news_headlines"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="50dp"
android:width="95dp"
style="@style/Text.News"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_below="@id/seperator2"
android:layout_alignParentBottom="true"/>

Any java code needed with this...please help.

Thanks,
guru.
