How to add a UI to a large android listview? -

-

i have android app displays custom contact list of 500 people , works fine; if looking name starts letter "s", takes forever scroll down.

how can program jump s without scrolling entire list?

here xml layout code:

<?xml version="1.0" encoding="utf-8"?> <linearlayout   xmlns:android="http://schemas.android.com/apk/res/android"   android:layout_height="fill_parent"    android:layout_width="fill_parent"   android:background="@color/background"   android:orientation="vertical">   <listview android="@+id/android:thelist" android:layout_height="0dip"    android:layout_width="wrap_content"    android:scrollbars="vertical"   android:fadingedge="vertical"   android:padding="2dp"    android:fastscrollenabled="true">   </listview>  <textview android:text="@+id/textview01"  android:layout_width="wrap_content"  android:layout_height="wrap_content"  android:id="@+id/label"  android:textsize="14dip"  android:textstyle="bold" android:paddingleft="10dip" android:paddingtop="3dip"></textview> </linearlayout>

have considered using fastscroll option?
