title: Android Gallary Example
body: <p>I have just done some code for Gallary and now its working fine.I have followed this Link for that <a href="http://developer.android.com/resources/tutorials/views/hello-gallery.html" rel="nofollow">http://developer.android.com/resources/tutorials/views/hello-gallery.html</a>. But my concept is still not clear.I have used there stylable, what is this?And one more thing, Is it possible to change gallary displaying mode(I mean its default mode is L-R or R-L can we change it Top-Bottom or Bottom-Top).</p>
  
  <pre><code>TypedArray attr = mContext
                  .obtainStyledAttributes(R.styleable.HelloGallery);
          mGalleryItemBackground = attr.getResourceId(
                  R.styleable.HelloGallery_android_galleryItemBackground, 0);
          attr.recycle();
  </code></pre>
