How do I remove lines between ListViews on Android?

I’m using two ListViews like this:

<ListView
   android:id="@+id/ListView"
   android:text="@string/Website"
   android:layout_height="30px"
   android:layout_width="150px"
   android:scrollbars="none"
   android:transcriptMode="normal"/>
<ListView
   android:id="@+id/ListView1"
   android:text="@string/Website"
   android:layout_height="30px"
   android:layout_width="150px"
   android:scrollbars="none"
   android:transcriptMode="normal"/>

There is one blank line between the two ListViews. How do I remove it?
