/**
 * This activity creates a listview whose items can be clicked to expand and show additional content.
 * 
 * In this specific demo, each item in a listview displays an image and a corresponding title. These two items are centered in the default (collapsed) state of
 * the listview's item. When the item is clicked, it expands to display text of some varying length. The item persists in this expanded state (even if the user
 * scrolls away and then scrolls back to the same location) until it is clicked again, at which point the cell collapses back to its default state.
