show multiple rows of HorizontalListView
<p>I am trying to display multiple <a href="http://www.dev-smart.com/archives/34" rel="nofollow">HorizontalListView</a> in a linearlayout. However, I can only see the firs HorizontalListView. All stuff after that disappeared. 
The following is the layout.xml`</p>

<pre><code>    &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/main_layout"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="#fff"
        android:orientation="vertical"&gt;

            &lt;com.devsmart.android.ui.HorizontalListView
                android:id="@+id/saladMenuView"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:background="#ddd"
                android:fillViewport="false" /&gt;

            &lt;com.devsmart.android.ui.HorizontalListView
                android:id="@+id/pizzaMenuView"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:background="#ddd"
                android:fillViewport="false" /&gt;
    &lt;/LinearLayout&gt;`
</code></pre>

<p>I can always see saladMenuView, but pizzaMenuView never shows up. </p>

<p>Does anyone know why? </p>
