Image gallery, like Facebook
<p>I would like to create an image gallery activity like Facebook. It should support 1 item scrolling , pinch zooming and lazy loading.</p>

<p>I tried to use <code>Gallery</code> but was unable to add zoom pinching support. I would like to know if Facebook used <code>ViewFlipper</code>, <code>ImageSwitcher</code>, <code>Gallery</code> or some kind of custom control.</p>
