Sorry for having just noticed this question now. Hopefully this answer can still be of use to someone...

Java is a case sensitive language. By capitalizing the 'S' in "SetOnclickListener" your IDE is reading it as an entirely new method hence autocomplete is ignoring you. EVERYONE MAKES MISTAKES LIKE THESE. I still do all the time. I've even seen TreeHouse instructors gloss over a typo and try to run their application.

As a side note, a common convention in many programming languages is naming fields and methods with camel case ie 'setOnclickListener'. https://en.wikipedia.org/wiki/CamelCase.

As another side note, I can't stress how helpful it was for my own learning to switch over to the java track before diving into this one. I have hardly mastered the language, but after returning to this track, I can follow along with greater ease. Unlike my first attempt at this track, I don't feel as though I'm just taking Ben's word for everything. Having knowledge of object oriented programming to rely on as a reference point is quickly paying off!
