Butter Knife @bind in Fragment error

I follow the instructions on the website : http://jakewharton.github.io/butterknife/

error : java.lang.RuntimeException: Unable to start activity ComponentInfo. java.lang.RuntimeException: Unable to bind views for com.project.myapp.OneFragment.

I try to remove

@Bind(R.id.btnNext) Button btnNext;
and run no error.

public class OneFragment extends Fragment {
@Bind(R.id.btnNext) Button btnNext;

private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";

private String mParam1;
private String mParam2;

private OnFragmentInteractionListener mListener;

public OneFragment() {
// Required empty public constructor
}
public static OneFragment newInstance(String param1, String param2) {
OneFragment fragment = new OneFragment();
Bundle args = new Bundle();
args.putString(ARG_PARAM1, param1);
args.putString(ARG_PARAM2, param2);
fragment.setArguments(args);
return fragment;
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
mParam1 = getArguments().getString(ARG_PARAM1);
mParam2 = getArguments().getString(ARG_PARAM2);
}
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_one, container, false);
ButterKnife.bind(this, view);

return view;
}
public void onButtonPressed(Uri uri) {
if (mListener != null) {
mListener.onFragmentInteraction(uri);
}
}
@Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof OnFragmentInteractionListener) {
mListener = (OnFragmentInteractionListener) context;
} else {
throw new RuntimeException(context.toString()
+ " must implement OnFragmentInteractionListener");
}
}

@Override
public void onDetach() {
super.onDetach();
mListener = null;
}
public interface OnFragmentInteractionListener {
void onFragmentInteraction(Uri uri);
}
}

Answer

Replace this:

ButterKnife.bind(this, view);

with

ButterKnife.bind(getActivity(), view);
