Error putting ImageButtons with sounds within fragment

I'm trying to put ImageButtons playing sounds inside a fragment called Tab1, however I'm encountering two errors:

Non-static method 'findViewById (int)' can not be referenced from a static context

on the line

final ImageButton vitasbut = tab1.findViewById(R.id.vitasbut);

and

Can not resolve method 'create (com.example.mateuspc1.memepocket.MainActivity.Tab1, int)'

lines in mediaPlayer = MediaPlayer.create(this, R.raw.gtaintro); (in all mediaPlayer.create).

Code:

public static class Tab1 extends Fragment {
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            return inflater.inflate(R.layout.tab1, container, false);



        }
        public Tab1() {
            final ImageButton vitasbut = tab1.findViewById(R.id.vitasbut);

            vitasbut.setOnClickListener(new ImageButton.OnClickListener() {
                @Override
                public void onClick(View v) {
                    vitasbut.setImageResource(R.drawable.vitas1);
                    play(vitasblblblahahah);
                    mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                        public void onCompletion(MediaPlayer mp) {
                            vitasbut.setImageResource(R.drawable.vitas1e2);
                        }
                    });
                }
            });}

Fragment works differently than Activity :

When building Activity, we use the onCreate () method, where we inform you what xml we will use through the setContentView (android.view.View) .

Already in the construction of Fragment , we use the method onCreateView () , where we return to View of the screen.

Because of this, Fragment does not have the findViewById method, but the View (returned in the onCreateView() method).

Try this:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
     View view = inflater.inflate(R.layout.tab1, container, false);
     final ImageButton vitasbut = view.findViewById(R.id.vitasbut);
     // Seu código com o botão vitasbut...
    return view;
}

I do not recommend using the Fragment constructor to initialize the objects on the screen, since it is invoked before Constructing the screen (call the onCreateView() method).
