android nested object parceling

Question

how can we parcel nested object in an intent?.
For example lets say there is an object A which contain one string variable and one another object B. now B contain object C . C contain a list of string. so how i can parcel object A in an intent.
any help on this will be appreciated.
thanks in advance.

Implementation:

public static class A 
{
    private B  ObjectB;
}

public static class B 
{
    private String type;
    private List<C> C;
}

public static class C 
{
    private List<D> D;
}

public static class D 
{
    private String id;
    private String name;
    private String address;
    private String email;
}

how to write parcelable for class C. i am using

dest.writeParceable(ObjectC,flag)

For reading:

in.readParcelable(C.getClass().getClassLoader());

but its not working

Answer 1

You would have to implement parcelable for object B and then implement parcelable for object A. I have never done this but the above should work.

Edit

See the code snippets below which illustrates how to implement parcelable for Class C.

1. First implement parcelable for Class D like so:

   dest.writeString(id); 
   dest.writeString(name);  
   dest.writeString(address);  
   dest.writeString(email);
   
   id = in.readString();  
   name = in.readString();  
   address = in.readString();  
   email = in.readString();  
   

2. Then implement parcelable for Class C as follows:

   dest.writeList(D);
   
   in.readList(D,this.getClass().getClassLoader());
   

This is untested code as I have never implemented nested parceling but worth a try. Hope that helps.
