Answer 1

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle 

    savedInstanceState) {
            View view = inflater.inflate(R.layout.capture_card_phone_number, container, false);
            mPhone = (AutoCompleteTextView) getActivity().findViewById(R.id.phone_number);
            Button next = (Button) view.findViewById(R.id.capture_phone_next);
            next.setOnClickListener(this);


            return view;

You have to call findViewById on your view - not on your activity.
