A quick reminder: if you are doing serious Android development, and are using neither styles, includes nor fragments to maximize re-usability, you are creating your own hell. You can set divider between every item and set its height and color as per your UI design. With ListView, user can easily browse the information, while scrolling up and down. Best example of it is our devices Contact List.

Notice that we have included the onClick handler in the XML, and that we are using styles. ListView in Android ListView is used when you have to show items in a vertically scrolling list. This example uses a TextView, but any View can be expanded/collapsed the same way. The Android SDK provides the ExpandableListView class, but sometimes that option is overkill or unfit for our intents & purposes, and we may decide to roll out our own mechanism.

What we are doing is trying to maximize the use of the available space on the screen by giving an overall view of its content. Expandable/Collapsible Views (text, images, etc.) in Android are useful when we want to display all the available options on one screen, without the user having to scroll all the way to find the one he/she is interested in.
