android - findViewById returning null in fragment

I am replacing the existing fragment with new fragment and i am able to see my view but while setting on click listener on the button it returns null . I get the following exception :

?:??: W/?(?): java.lang.NullPointerException
?:??: W/?(?):   at com.biggu.shopsavvy.fragments.xxxxxxxx.onCreateView(xxxxxx.java:34)
?:??: W/?(?):   at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:870)

?:??: W/?(?):   at dalvik.system.NativeStart.main(Native Method)

I have no clue what is happening ?

The code on OnCreateView :

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) getActivity().findViewById(R.id.capture_phone_next);
        next.setOnClickListener(this);
        // next.setEnabled(false);

        return view;

I have also imported com.big.xxxxxxx.R

Thanks in advance for your help

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.
