When I edit XML files in Eclipse using Android Common XML Editor I am only able to use the graphical layout editor. I see in pictures online how there are supposed to be tabs at the bottom for Graphical and Source but I have none. How do I get this fixed? Using Eclipse 4.2.1. Thanks!
That is probably a problem of Unity not displaying the editor correctly. I bet that you can still switch between the tabs using the keyboard. Press ShiftAltF7 to navigate to the previous page and AltF7 to navigate to the next page of a multi page editor.
