I am also a beginner and from what I understand: Activity objects are used to pass Intent objects to and from other Activity objects. Each Activity would have it's own View object associated with it. A layout is simply a list of UI element parameters for each Activity. A Layout, as in android.text.Layout, is a class for setting text in the UI elements. http://developer.android.com/reference/android/text/Layout.html
I guess if you had multiple layout screens for a single Activity, you would still need to create the window and according to the documentation: "Almost all activities interact with the user, so the Activity class takes care of creating a window for you in which you can place your UI with setContentView(View)." http://developer.android.com/reference/android/app/Activity.html I have not looked to see the other ways in which you could create a window without using setContentView(View), unless you subclassed android.app.Activity. I hope this helps.
