you are not switching from activity to another activity. u r just changing the view. for switching b/n activities u should use intents.
as for ur exception i guess it says the specified child has a parent, since ur tries to set the view R.layout.main twice in ur code. so first remove the view and then add it when the button b2 is clicked.
