Adapter call void

I am beginner in Android so, sorry for my probably noobie question. I've got RecyclerView list in my application. I created DataAdapter and Activity for that. I also created two layouts: favorite_items(assigned to Data Adapter) and favorite_activity(assigned to Activity). In favorite_items layout(Data Adapter) I've got button "Share" and in Activity I've got function(ButtonLogic). I would like to call function from activity but i don't know how. I must add that RecyclerView works fine.

ACTIVITY

public void ButtonsLogic(){

   mShare.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
          String s = Textview.getText().toString();
          Intent sharingIntent = new Intent(Intent.ACTION_SEND);
          sharingIntent.setType("text/plain");
          sharingIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
          sharingIntent.putExtra(Intent.EXTRA_TEXT, s);
          startActivity(Intent.createChooser(sharingIntent, "Share data:"));

      }
});

ADAPTER

public class FavoriteAdapter extends RecyclerView.Adapter<FavoriteAdapter.FavoriteViewHolder> {


    //this context we will use to inflate the layout
    private Context mCtx;

    //we are storing all the products in a list
    private List<Favorite> favoriteList;

    //getting the context and product list with constructor
    public FavoriteAdapter(Context mCtx, List<Favorite> favoriteList {
        this.mCtx = mCtx;
        this.favoriteList= favoriteList;
    }

    @Override
    public FavoriteViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        //inflating and returning our view holder
        LayoutInflater inflater = LayoutInflater.from(mCtx);
        View view = inflater.inflate(R.layout.favorite_items, null);
        return new FavoriteViewHolder(view);
    }

    @Override
    public void onBindViewHolder(FavoriteViewHolder holder, int position) {
        //getting the product of the specified position
        Favorite favorite= quoteModelList.get(position);

        //binding the data with the viewholder views
        holder.Favoritetext.setText(favorite.getFavoriteText());


    }


    @Override
    public int getItemCount() {
        return favoriteList.size();
    }


    class FavoriteViewHolder extends RecyclerView.ViewHolder {

        TextView Favoritetext;


        public FavoriteViewHolder(View itemView) {
            super(itemView);
            Favoritetext = itemView.findViewById(R.id.favoritetextview);


        }
    }
}

Create an interface like this

interface Listener {
    private void onItemClicked(String text);
}

and implement it in your Activity. When you construct your adapter, pass this interface

public FavoriteAdapter(Context mCtx, List<Favorite> favoriteList, Listener listener) {
    this.mCtx = mCtx;
    this.favoriteList= favoriteList;
    this.listener = listener

}

Set the listener in your bind method

@Override
public void onBindViewHolder(FavoriteViewHolder holder, int position) {
    //getting the product of the specified position
    Favorite favorite= quoteModelList.get(position);

    //binding the data with the viewholder views


    holder.Favoritetext.setText(favorite.getFavoriteText());
    holder.button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            listener.onIemClicked(/* get text to pass to activity */);
        }
    };
}
