Gson ignore json field and deserialize - android

I'm working with android and gson and i was wondering if i can ignore a field from the webservice.
this its my gson object
Gson gson = new GsonBuilder().serializeNulls().create();
So what i need is to ignore validator field and deserialize to my custom bean in the following code.
Its any way to do that with gson ?
{ "posts":
[
{
"username": "John",
"message": "I'm back",
"time": "2010-5-6 7:00:34"
"validator":[{
"prog": "Name1",
"name": "Name2",
"computername": "Name3",
"date": "2010-11-20 19:39:55"
}]
}
,
{
"username": "Smith",
"message": "I've been waiting",
"time": "2010-4-6 10:30:26"
"validator":[{
"prog": "Name1",
"name": "Name2",
"computername": "Name3",
"date": "2010-11-20 19:39:55"
}]
}
]}
Thanks in advance
Cheers

You can call gson.fromJson(inputString, localObject) and if localObject doesn't declare a validator variable, it will just skip it.

Check this out. Create a generic response class. Extend your classes from that class. To do this properly you can look at Java Generics and Inheritance topics if you are using Java. And then search about Sectioned RecyclerView in Android. Here is a library for this.

your enum:
enum CreditCardType{

}
and while parsing, when you reach till type
//param is JSONObject
CreditCardType card = CreditCardType.valueOf(param.getString("name"));
