I would probably recommend not trying to change views within an activity. While in theory it could be done it is not really the recommended way and there have been multiple posts with people trying to do this and running into multiple problems. Most of them eventually end up switching to using different activities and wasted a lot of development time trying to just switch views within one activity.
It also tends to violate the really good programming practice of having things do one thing, and one thing only... That being said, there may be some cases where just switching views within an activity would be acceptable and normal thing to do. I haven't really come across the need in my own programming efforts to do that. An activity should serve one purpose and one purpose only. I guess an acceptable reason to do that might be if you had multiple layouts for an activity that just presented the same information to the user in a different way then that would be ok. It's all a matter of preference but the Android way is to use activities. They have all sorts of options for controlling how they behave as well that you can set in the manifest file. ---------------------------------------------------------------------- There are only 10 types of people in the world...
