I have just recently egan trying to learn the ows of writting Android apps. I have created a simple applcation that just has 3 buttons on the main laout and a layout for what each buton does. However once I have switched the layout based upon what button was pressed, where does the code for the new layout go? How does one get back to the main layout from the alternate layout?

Thank you in advance,
Dire

Well you could use a view flipper and both layouts go into the same xml file. But. The correct way to handle this in Android is to make seperate activities and call each activity using an intent. Each activity gets its own view xml and java file, but stays in your project folder. You must declare each activity in your manifest. Just make a different activity for each of your main buttons (unless they do something similar in which case you would send the different selection info as a bundle to your intent). Reply if you need more info and I'll post up more later today.
