text for marquee dynamically

Question

Is it possible to add text from java coding of a list view to marquee scroll in Android. If yes can you please let me know how?

If needed I shall post the code used. This was the XML for listview used is as follows

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >
     <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >
    </LinearLayout>
    <ListView
        android:id="@+id/audiolist_listView"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_gravity="bottom"
        android:layout_weight="1"
        android:background="@drawable/backgroundimg"
        android:divider="@drawable/gradient"
        android:dividerHeight="1dp"
        android:scrollbars="vertical" >
    </ListView>

</LinearLayout>

The java class for listview is as follows

public class Audiovediolist extends Activity implements OnItemClickListener {
    private ListView audioList;
    private Intent frmHome;
    private ArrayList<HashMap<String, String>> dataList;

If you need to move text around, maybe this will help:

http://developer.android.com/guide/topics/resources/animation-resource.html#translate-element

If you have a TextView with a text that is too big and you want it to move around so people can read the whole thing, try android:ellipsize="marquee" in the .xml file, or in the Java code: textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);
