Scroll view does't resize when the content of child view changes
<p>I have a <code>WebView</code> inside the <code>ScrollView</code>.</p>

<p>The content of <code>WebView</code> dyanamically changes when it displays different html page. </p>

<p>I have the following issue:</p>

<p>For example I have <code>A.html</code>, and <code>B.html</code>. The content of <code>B.html</code> is larger than <code>A.html</code>, so the page is longer.</p>

<p>When <code>WebView</code> load <code>B.html</code>, the ScrollView stretches its size to enable itself scroll for B.html, then if I go back to <code>A.html</code>, ScrollView doesn't resize itself. (The scroll area is exceed the content of <code>A.html</code>)</p>

<p>What I want to have, is dynamic change the scroll area of scroll view to fit the webview's content.</p>

<p>Any idea or suggestion</p>
