Android: findviewbyid: finding view by id when view is not on the same layout invoked by setContentView

Question

I have an activity MyActivity that extends from MapActivity. In the .xml file containing the layout I can only include the MapView

Answer 1

It's impossible. You can only find and access views that are currently running. If you want to check the value of ex. TextView used in previus activity you must save the value is SharedPreferences, database, file or pass by Intent.
