title: using pinch in the webview android
body: <p>I have two questions:</p>
  
  <ul>
  <li><p>I find this code to use pinch in the <code>webImageView</code> but when I change <code>webImageView</code> by <code>WebView</code>. I obtain an error in the code. how I use pinch in the <code>webview</code>??    </p>
  
  <pre><code> // create the WebImageView object from xml
  WebImageView img = (WebImageView) findViewById(R.id.main_pic);
  // fetches the image in a background thread
  img.setImageFromURL("http://www.mysite.com/mypicture.jpg");
  // enable pinch-zoom abilities on the image
  new PinchImageView(img);
  </code></pre></li>
  <li><p>When I add pinch in my code is that supported by all the mobile android or you should have a specific screen to make it work it.</p></li>
  </ul>
