Variables with underline

Question

I\'m getting an underline in some variables on Android Studio (in this case on the \'position\' variable). I think it\'s not an error because the application runs perfectly

Answer 1

I believe the underlined variables are representative of constants (final or effectively final), because in my experience I only see this decoration when I declare a final object for use inside an anonymous class. I can't seem to find it in the documentation, though.
