You can use Map for parsing json with dynamic keys. this link might help you. which uses gson to parse json.
check this link also. check out the documentation of gson here.

Dynamic JSON parsing

I am a newbie to android. I am stuck at JSON parsing.
Following is my JSON, in this, the type of menu categories will be dynamic, and I want to arrange this JSON in sectioned recycler view.
Please help me out.
This is my JSON
{
"menu_items": {
"Plat": [{
"menu_name": "jambon à l'os",
"menu_cost": "18.00",
"menu_count": "1",
"category": "Plat",
"menu_tax": "5.50",
"code": "€"
},
{
"menu_name": "tacos",
"menu_cost": "6.00",
"menu_count": "1",
"category": "Plat",
"menu_tax": "5.50",
"code": "€"
}
],
"Entrée": [{
"menu_name": "avocat",
"menu_cost": "7.50",
"menu_count": "1",
"category": "Entrée",
"menu_tax": "5.50",
"code": "€"
}]
},
"order_data": {

},
"promo_applied": "0",
"error": {
"code": "13",
"status": "200",
"message": "Ok"
}
}

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.

Gson ignore json field and deserialize

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.
