android - dialog with dynamic listview at top and container at bottom + AutoSize Dialog

    android:id="@+id/illBottom"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:paddingLeft="4dip"
    android:paddingRight="4dip" >

</com.actionbarsherlock.internal.widget.IcsLinearLayout>

Maybe the Build-in-List does it for you:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setSingleChoiceItems(....
