Custom Updatable ListView - Android Development

As a goal for my first Android application to learn the Android SDK, I am trying to开发者_开发技巧 create a simple RSS viewer for a specific url. Disregarding the networking side of the goal, I am having trouble with getting a listView to display a custom layout.

What I'd like to do is have each row of a list view show one of two images(read or unread), followed by some text. I'm not really having a problem, it's more that there aren't any examples that I could find (I might be looking in the wrong place) that covered custom layouts depending on conditions in code.

Any help?

Here is a free excerpt from one of my books that discusses the techniques involved. In a nutshell, you will need to extend your Adapter class (e.g., ArrayAdapter, CursorAdapter) and take direct control over the creation of rows, so you can apply your desired business logic.
