Try this inside onCreateView

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.events_layout, null);

        -------------some codes ------------

        stackView = (StackView) view.findViewById(R.id.stackView1);

        return view;

    }
