The method receives a character array with the element content in it, so the code works through this andfoid in a loop structure. When you process XML data with SAX, the program moves through the data in a linear fashion, so flags can help to detect what point of the document your app is at when each method executes.
You should be able to adapt the code to suit the needs of your own Android projects. For your own projects, you can use more sophisticated display methods, such as making the items interactive.
