<HorizontalScrollView
        android:id="@+id/xml_full_img_hor_below_view"
        android:layout_width="match_parent"
        android:layout_height="@dimen/full_img_below_relative_height"
        android:layout_alignParentBottom="true"
        android:layout_gravity="center"
        android:orientation="horizontal" >

        <LinearLayout
            android:id="@+id/xml_full_img_linear_below_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center"
            android:orientation="horizontal" >
        </LinearLayout>
    </HorizontalScrollView>
