title: getAdapterPosition() is not found as a method
body: <p>I recently uprated to Android Studio 2.3 and not the getAdapterPosition (RecyclerView) cannot be found. I saw on the web that the reason for that is the support library version. But I am not sure how to solve it still. My support:appcompat-v7:25.2.0' version is the latest possible (e.g. above 21). I don't understand why the method is not found. Any advice, please? </p>
