What i have done in my project is

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

    <Button
        android:id="@+id/task_title"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="@string/tasks" />

    <ListView
        android:id="@id/android:list"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/task_title" 
        android:layout_above="@+id/add_button">
        <!-- Preview: listitem=@layout/task_list_item -->
    </ListView>

    <TextView
        android:id="@id/android:empty"
        android:text="@string/no_tasks"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical|center_horizontal"
        android:layout_below="@id/task_title" 
        android:layout_above="@id/add_button"/>


    <Button
        android:id="@id/add_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:text="@string/plus_sign" />

    <Button
        android:id="@+id/remove_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_toRightOf="@id/add_button"
        android:text="@string/remove_task" />

</RelativeLayout>

With relative layout you can simply do it, the key layout properties are android:layout_alignParentBottom="true" , android:layout_alignParentTop="true"
