Answering my own question. When prototyping the app, I'd programmatically instantiated the MyView. Later, I'd added an entry of MyView in the main.xml file. Thus, I had two instances of the MyView object, one on top of the other. Thus, redraws were happening on the instance underneath the top instance.
