[Android Studio] Hardcoded string Button, should use @string resource

Warning Message:

Hardcoded string "Button", should use @string resource

Hardcoding text attributes directly in layout files is bad for several reasons:

* When creating configuration variations (for example for landscape or portrait) you have to repeat the actual text (and keep it up to date when making changes)

* The application cannot be translated to other languages by just adding new translations for existing string resources.

There are quick-fixes to automatically extract this hardcoded string into a resource lookup.
