How do I go about implementing Android UI, specifically this gallery?
<p>This question has 2 parts:</p>

<p>1) I'm new to Android development and find implementing the UI on Android quite overwhelming. It would be great help if you could point me to some free UI libraries or give me some advice on how mobile developers go about implementing the UI. Is there some framework of "standard" UI framework which I can use to build simple stuff that aren't directly possible from the Android API? I want to focus more on the content of the app rather than building all the quite common design patterns from scratch.</p>

<p>2) Currently, I'm building an app, which needs to have a gallery. I'm thinking of this</p>

<p><img src="http://i.stack.imgur.com/2AU2o.jpg" alt="Gallery design pattern"></p>

<p>I want to supply a <code>Vector</code> of <code>Photo</code> (which contains URL to the thumbnail and the actual sized image) to this <code>View</code> and get something like that.</p>

<p>Thanks</p>
