Problems with Serializable

I have a problem with a program that I `m design:

public void LoadVehicules()
{
Intent intent=new Intent(this,pspsl.g.listviewrealtimeinfo.class);
intent.putExtra("doGetInfoRealTimeResult", doGetInfoRealTimeResult.toString());
intent.putExtra("doGetInfoRealTimeResult", true);
startActivity(intent);
}

doGetinfoRealTimeResult type is Array of Objects and I want to pass this array list to another window of the program to put the information that it contain in the screen.

My problem is, How Can I serializable an array list of objects??

Thanks.

Each object in the object array needs to implement the serializable interface.
The example below works well..

class A implements Serializable {
 
        private static final long serialVersionUID = 1L;
 
        private int muh;
 
        private String wuff;
 
        private HashMap<String, String> miau;
 
        public A() { this.muh = 1; this.wuff = "2"; this.miau = new HashMap<String,String>(); }
 
}
 
class B implements Serializable {
 
        private static final long serialVersionUID = 2L;
 
        private A myA;
 
        public B() { this.myA = new A(); }
 
}
 
public class Test extends Activity {
 
    public void onCreate(Bundle savedInstanceState) {
 
        super.onCreate(savedInstanceState);
 
        setContentView(R.layout.main);
 
        Intent i = new Intent(this, Test.class);
 
        i.putExtra("test", new A());
 
        i.putExtra("test", new B());
 
        ArrayList<B> blist = new ArrayList<B>();
 
        blist.add(new B());
 
        blist.add(new B());
 
        blist.add(new B());
 
        ArrayList<A> alist = new ArrayList<A>();
 
        alist.add(new A());
 
        alist.add(new A());
 
        alist.add(new A());
 
        i.putExtra("test", alist);
 
        i.putExtra("test", blist);
 
        startActivity(i);
 
    }
 
}
