I have a question regarding fragments. I would like to implement a simple fade in animation into my first fragment "Pageone"

Here you can see my Fragmentmanagerclass "Home":

public class Home extends AppCompatActivity {

ViewPager vpager;



@Override



protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_home);

    vpager= findViewById(R.id.vPager);

    vpager.setAdapter(new setViewadapter(getSupportFragmentManager()));

}

public class setViewadapter extends FragmentPagerAdapter {

    public setViewadapter(FragmentManager fm) {

        super(fm);

    }

    @Override



    public android.support.v4.app.Fragment getItem(int position) {

        if(position==0) {

            return new Pageone();

        }

        else if (position==1){

            return new Pagetwo();

        }

        else if (position==2){

            return new Pagethree();

        }

        else

            return new Likeandfollow();

    }



    @Override



    public int getCount() { return 4; }

I would like to add the animation like this to the class "Pageone" which is the first fragment:

public class Pageone extends Fragment {

    @Nullable

    @Override



    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container,



                             @Nullable Bundle savedInstanceState) {

        View v=inflater.inflate(R.layout.activity_pageone,null);

        return v;



        View rootView=inflater.inflate(R.layout.activity_pageone, container, false);

        Button button = (Button) getActivity().findViewById(R.id.button);

        Animation slideIn = AnimationUtils.loadAnimation(getActivity(), R.anim.mytransition);

        button.startAnimation(slideIn);

        return rootView;



    }

}

No error appears, but the app crashes when starting Pageone fragment.
