<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"

<ListView

android:layout_height="fill_parent"
android:id="@+id/itemlist" android:layout_gravity="left"

</LinearLayout>
