title: horizontalscrollview's fillviewport disables scrolling?
body: <p>I have this layout, and it's scaled weirdly (probably due to inadviseable layout nesting) if I do not use fillviewport=true in my HorizontalScrollView. </p>
  
  <p>Everything works peachy (except for the odd scaling) when fillviewport=false, but when fillviewport=true, the scaling is perfect but no scrolling happens. </p>
  
  <p>This is the layout (Note: I know you're not supposed to put a webview in a scrollview. But webview doesn't have a smoothscrollto nor expose a setscroller method, so ... bleh.) </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;HorizontalScrollView 
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/webContainer"
      android:layout_below="@+id/titlebar"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:fillViewport="true"&gt;
      &lt;WebView 
          xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/webZ"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
      /&gt;
  &lt;/HorizontalScrollView&gt;
  </code></pre>
  
  <p>Setting android:fillViewport="true" doesn't usually disable scrolling in a view, does it?</p>
  
  <p>It's just supposed to be sure the scrollview fills the viewport regardless of the size of its contents, eh? I think the viewport is the visible area of the screen, and there is definitely more content off the edge of the visible area in the webview, I just can't scroll to it anymore. </p>
  
  <p>I can see from logcat that the scrolling methods are being called, they just don't change the screen. (Unless I set fillviewport to false.) </p>
