tuo XML non contiene il layout esterno, ma suppongo che è un layout relativo. In un RelativeLayout, i livelli z degli elementi sono determinati dall'ordine in cui vengono aggiunti al contenitore. La vista aggiunta più tardi sarà in cima. Prova a spostare il cassetto scorrevole sul fondo del contenitore esterno. Ti piace questa -

<ListView android:id="@+id/listView1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:stackFromBottom="true" 
    android:transcriptMode="alwaysScroll" 
    android:layout_above="@+id/InnerRelativeLayout" 
    android:layout_alignParentTop="true" 
/> 
<RelativeLayout 
    android:id="@+id/InnerRelativeLayout" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentBottom="true" > 
    <Button 
     android:text="kirim" 
     android:id="@+id/button_send" 
     android:layout_alignParentRight="true" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:onClick="tambahItems"   
     > 

    </Button>   
</RelativeLayout>
