  android:orientation="horizontal"
   android:layout_width="fill_parent"
  android:layout_above="@+id/score_layout">
  <ScrollView android:layout_height="wrap_content" 
  android:id="@+id/scrollView1" 
  android:layout_width="fill_parent" 
  >
      <LinearLayout android:layout_width="fill_parent" 
      android:id="@+id/scoreball_layout" 
      android:layout_height="wrap_content"
      android:isScrollContainer="true" 
      android:scrollbars="horizontal">
