        android:background="@drawable/savebutton" android:layout_height="wrap_content"
        android:id="@+id/done"></Button>
</RelativeLayout>

The reason that the layout is not showing is layout_marginBottom="82dip" on the ScrollView

So changing:

<ScrollView android:id="@+id/sos_scroll"
    android:layout_marginBottom="82dip" android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:layout_below="@+id/date"
    android:layout_marginTop="5dip" android:fadingEdge="none"
    android:scrollbars="none">

to for example:

<ScrollView android:id="@+id/sos_scroll"
    android:layout_marginBottom="1dip" android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:layout_below="@+id/date"
    android:layout_marginTop="5dip" android:fadingEdge="none"
    android:scrollbars="none">

should help.
