title: How to make a 2-dimension image gallery with both horizontal and vertical scrolling?
body: <p>I'm new to Android and I want to make an image gallery where each column is a category, and users can scroll both vertically and horizontally. </p>
  
  <p>I found a useful post about how to display list of images <a href="https://stackoverflow.com/questions/459729/how-to-display-list-of-images-in-listview-in-android">here</a>. I'm wondering if it's possible to nest lists of image inside of a gallery view? </p>
