How to pass data received from an activity and put it in a recyclerview

Hello, I'm a beginner in java programming and I'm having trouble passing some serialized information from an activity to a recyclerview.

When the second activity starts, it does not contain any information. Before trying to put in the recyclerview I tried using Textview and it worked, however when replacing for a recycler it does not bring any information. I think it's simple, but since I'm a beginner, I have no idea.

Below is the project code.

Thanks in advance for the help.

MainActivity

private void onOrderProduct() {
    bOrder.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            Cart cart = new Cart();
            cart.setComida(tvTitle.getText().toString());
            cart.setPreco(tvTotal.getText().toString());
            cart.setQuantidade(tvQtd.getText().toString());

            Intent intent = new Intent(MainActivity.this, SecondActivity.class);
            intent.putExtra("cart", cart);
            startActivity(intent);
        }
    });
}

SecondActivity

public class SecondActivity extends AppCompatActivity {
RecyclerView rvCart;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.secondactivity);

    rvCart = (RecyclerView) findViewById(R.id.tela5recycler_view);
    rvCart.setHasFixedSize(true);

    LinearLayoutManager manager = new LinearLayoutManager(this);

    rvCart.setLayoutManager(manager);


    if (getIntent().getSerializableExtra("cart") != null) {


        Intent intent = getIntent();

        Cart cart = (Cart) intent.getSerializableExtra("cart");

        ArrayList<Cart> eList = new ArrayList<>() cart;
        Adapter adapter =new Adapter(getApplicationContext(), eList );
        rvCart.setAdapter(adapter);
        adapter.notifyDataSetChanged();

    }

}
}

Adapter

public class Adapter extends RecyclerView.Adapter<Adapter.ItemViewHolder> {

private Context context;
private ArrayList<Cart> itemList;

public Adapter(Context context, ArrayList<Cart> itemList){
    this.context = context;
    this.itemList = itemList;
}

@Override
public ItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View view = inflater.from(parent.getContext())
            .inflate(R.layout.adapter_card, parent, false);

    ItemViewHolder itemViewHolder = new ItemViewHolder(view);
    return itemViewHolder;
}

@Override
public void onBindViewHolder(ItemViewHolder holder, int position) {

    Cart item = itemList.get(position);

    holder.tvQtdcard.setText(item.getQuantidade());
    holder.tvComidacard.setText(item.getComida());
    holder.tvPrecocard.setText(item.getPreco());

}



@Override
public int getItemCount() {
    if(itemList != null){
        return itemList.size();
    }
    return 0;
}
public static class ItemViewHolder extends RecyclerView.ViewHolder{

    public CardView cvItem;
    public TextView tvQtdcard, tvComidacard, tvPrecocard;

    public ItemViewHolder(View itemView) {
        super(itemView);
        cvItem = (CardView)itemView.findViewById(R.id.tela1_1_1_1_1card);
        tvQtdcard = (TextView)itemView.findViewById(R.id.tela5qtdcard);
        tvComidacard = (TextView)itemView.findViewById(R.id.tela5comidacard);
        tvPrecocard = (TextView)itemView.findViewById(R.id.tela5precocard);


    }
}
}

Serializable Cart.class

import java.io.Serializable;



public class Cart implements Serializable{

private static final long serialVersionUID = 42L;
private String comida;
private String quantidade;
private String preco;

public String getComida() {
    return comida;
}

public void setComida(String comida) {
    this.comida = comida;
}

public String getQuantidade() {
    return quantidade;
}

public void setQuantidade(String quantidade) {
    this.quantidade = quantidade;
}

public String getPreco() {
    return preco;
}

public void setPreco(String preco) {
    this.preco = preco;
}

public String toString(){
    return comida;
}
