@Override error

I am currently working through the "Implementing Designs for Android" track and I'm using android studio instead of eclipse. I've been adapting my code to make the project work in android studio, however I can't figure out how to fix the step I'm currently on now. I am getting an error on the following:

@Override public View onCreateView

@Override is underlined in red and the error message is saying "Method does not override method from its superclass". What do I do to correct this?
