How to pass data from recyclerview to activity by clicking activity button?

Question

When I click the PLAY button in Activity, I want to get some data in RECYCLERVIEW (For example, Song1, Song2, Song3.. data). How can I do that? Can you help with the code? I'm new at this. Here are my codes:

This is Model:

public class MyModel {

String songName, songURL;

public MyModel(String _songName, String _songURL) {
    this.songName = _songName;
    this.songURL = _songURL;
}

// Getters and setters

}

This is a Adapter:

public class MyAdaptor extends RecyclerView.Adapter<MyAdaptor.MyHolder> {

    ArrayList<MyModel> ayetList;
    LayoutInflater layoutInflater;
    Context mContext1;
    View view;

    public MyAdaptor(Context mContext, ArrayList<MyModel> _ayetList) {
        this.ayetList = _ayetList;
        mContext1 = mContext;
        layoutInflater = LayoutInflater.from(mContext);
    }

    public class MyHolder extends RecyclerView.ViewHolder {
        TextView tv_songname;
        SeekBar sb_song;

        public MyHolder(@NonNull View itemView) {
            super(itemView);
            tv_songname = itemView.findViewById(R.id.tv_songname);
            sb_song = itemView.findViewById(R.id.sb_song);
        }

        public void setData(MyModel ayetModel, int pozisyon) {
            tv_songname.setText(ayetModel.getSongName());
           
        }

    }

    @NonNull
    public MyHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        view = layoutInflater.inflate(R.layout.song_item, parent, false);
        return new MyHolder(view);
    }

    public void onBindViewHolder(@NonNull MyHolder holder, int position) {
        MyModel selectedProduct = ayetList.get(position);
        holder.setData(selectedProduct, position);
    }

    public int getItemCount() {
        return ayetList.size();
    }

}

This is the part I want to process. Here I want to get the data from the recyclerview by clicking the PLAY button.

This is a Activity:

Button btnPlay;
RecyclerView rwSongs;
Context context = this;
MyAdaptor myAdaptor;
MyModel myModel;
ArrayList<MyModel> mainList = new ArrayList<>();

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_player);

    btnPlay = findViewById(R.id.btnPlay);
    rwSongs = findViewById(R.id.rwSongs);
    
    rwSongs.setLayoutManager(new LinearLayoutManager(context));
    
    getData();

   img_Play.setOnClickListener(view -> {
       //I don't know what to do next ...
   });


}


private void getData() {
    .
    .
    .
    for (int i = 0; i < _dataArrayItiraf.length(); i++) {
        JSONObject jsonItiraf = _dataArrayItiraf.getJSONObject(i);
        String _SongName = jsonItiraf.getString("SongName");
        String _SongURL = jsonItiraf.getString("SongURL");

        myModel = new MyModel(_SongName, _SongURL);
        myModel.setSongName(_SongName);
        myModel.setSongURL(_SongURL);
        mainList.add(myModel);
    }
    myAdaptor = new MyAdaptor(context, mainList);
    rwSongs.setAdapter(myAdaptor);
    .
    .
    .
}

I will look forward to all your help. Thanks...
