Pass object that contains objects to Activity via Intent

Question

I have an Object that I need to pass via the Intent to another Activity via the onclick method.

I was following this answer here How to send an object from one Android Activity to another using Intents? Which works fine however my Object has within it an Array of objects.

How do I pass this object with its Array of Objects?

Below are the classes before using Parcelable

List (the object to be passed)

public class List  {

    private String Name;
    private ArrayList<ListItem> items;

    public List(){
        items = new ArrayList<ListItem>();
    }

    public void addItem(String title, String d, String s, int p){
        ListItem i = new ListItem();
        i.setDecription(d);
        i.setPrice(p);
        i.setSite(s);
        i.setTitle(title);
        items.add(i);
    }

    public String getName() {
        return Name;
    }
    public void setName(String Name) {
        this.Name = Name;
    }
    public int getCount() {
        return items.size();
    }

    public ArrayList<ListItem> getList(){
        return items;
    }
}

ListItem

public class ListItem {

    private String  title;
    private String  decription;
    private String  site;
    private int     price;


    public void setTitle(String title) {
        this.title = title;
    }
    public void setDecription(String d){
        this.decription = d;
    }
    public void setSite(String s){
        this.site = s;
    }
    public void setPrice(int i){
        this.price = i;
    }

    public String getTitle(){
        return title;
    }
    public String getDecription(){
        return decription;
    }
    public String getSite(){
        return site;
    }
    public int getPrice(){
        return price;
    }
}

So how would I use Parcelable on List to send the ArrayList as well.

THank you and if you need any more info please ask!

You shouldn't use List as your own type. It's a java standard library interface. — VM4, Aug 05 '13 at 18:29

@Raghunandan yes I had seen this but he only has normal data types within their object — DevWithZachary, Aug 05 '13 at 18:38

You're trying to pass around data that shouldn't normally be passed around. A list is an ideal candidate for an SQLite Database. Try that or another way to persist data in android: http://developer.android.com/guide/topics/data/data-storage.html

If you insist on using Parcelable: How can I make my custom objects Parcelable?

Also don't use List as your own type, it's standard JAVA.
