1 If you want to add Button as the last element of the list view

You must create custom ListAdapter for your ListView which will create a view with a Button in the getView method. You should decide how to return your custom view for the last element, you can hardcode it (return element count +1 in getCount method and return custom view in getView when position > element count) or you can add element to the structure you will be taking data from (Array, Cursor etc.) and check if field of element have certain value

2 If you want to add element below list view

You should use android:layout_width attribute and make ListView and "empty" TextView (you should use it to show users that list is empty and View rendering is completed) layout_weight greater than buttons layout_weight

Check how it's done in Transdroids search Activity http://code.google.com/p/transdroid/source/browse/trunk/res/layout/search.xml

You could, of course, use a custom adapter and specify a footer item. But you could probably also get away with putting it at the bottom of a ScrollView and have the ListView stretch vertically to the content:

<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/main_bg">

  <ScrollView
      android:layout_height="fill_parent"
      android:layout_width="fill_parent">

    <LinearLayout 
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
            >

      <ListView android:id="@+id/android:list"
          android:layout_width="fill_parent" 
          android:layout_height="wrap_content"
          android:drawSelectorOnTop="false" 
          android:cacheColorHint="#ff6a00"
          android:divider="#ff8f40"
          android:dividerHeight="1px"
          />

      <RelativeLayout 
          android:layout_width="fill_parent"
          android:layout_height="50sp"
          android:background="#676767"
          android:orientation="vertical">

        <Button android:layout_width="100px"
            android:layout_height="wrap_content"
            android:id="@+id/btnGetMoreResults"
            android:layout_marginLeft="10px"
            android:text="Get more" />

      </RelativeLayout>

    </LinearLayout>

  </ScrollView>

</RelativeLayout>

You may want to use [ListView#addFooterView][1] to add a View at the bottom of the ListView.
