Volley와 gson을 써서 데이터를 받아옵니다. 받아온 데이터를 메인액티비티에서 ViewPager를 담고 있는 Fragment로 데이터를 전달하고 싶은데 Viewpager Fragment에 Budle로 데이터를 담아서 Viewpager Fragment가 OnCreateView되는 시점에 getArgument로 받는데 자꾸 nullpoint에러가 나네요.... 왜그런걸까요?

public void processRespons(String response) {
    Gson gson = new Gson();

    ResponseInfo info = gson.fromJson(response, ResponseInfo.class);
    MovieList movieList = gson.fromJson(response, MovieList.class);
    if (info.code == 200) {
        MovieInfo movieInfo = movieList.result.get(1);
        String title = movieInfo.title;
        Bundle bundle = new Bundle();
        bundle.putString("title", title);

        ViewPager1 viewPager = new ViewPager1();
        viewPager.setArguments(bundle);

    }
}


public View onCreateView(@NonNull final LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    rootView = (ViewGroup) inflater.inflate(R.layout.view_pager1, container, false);

    Button button = rootView.findViewById(R.id.viewpager1_button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Bundle bundle = getArguments();
            String title = bundle.getString("title");

            TextView text = rootView.findViewById(R.id.viewpager1_title);
            text.setText(title);


        }
    });
