First, have your class implement Serializable , example:

public class Carro implements Serializable{}

In your intent you make a cast for serializable:

List<Carro> list = new ArrayList<Carro>();
myIntent.putExtra("LIST", (Serializable) list);

In the second Activity you can get the list like this:

Intent i = getIntent();
list = (List<Carro>) i.getSerializableExtra("LIST");

There are more performative ways to pass parameters between acitivities using Parcelable .
