I'm loading a GLSurfaceView, which extends SurfaceView, which extends View. So, yeah.
There shouldn't be any problem classloading an Activity, use reflection to instantiate, and treat as you would a runtime Activity (as opposed to being declared in AndroidManifest.xml). But I haven't actually done this; could be some gotchas in incorporating runtime a Activity into the GUI.
IIRC google had a few hits on classloading Activities.
