Nested JSON random name objects parse with Gson

Question

im looking to a simple way to parse this JSON into a Gson java class for easily way to put him into a adapter and fill some listviews the problem is the part of items,i dont know the items objects names, as you can see i have random objects names inside items, is possible do to this with GSON or i need another code logic, this is for Android, thanks for your help :

[{
    "id": 1001,
    "name": "Super1",
    "user": {
        "name": "The Super 1"
    },
    "items": {
        "987987M7812b163eryrt": {
            "id": 1,
            "strong": 456,
            "active": true,
            "sell": "te"
        },
        "90812bn120893juuh": {
            "id": 2,
            "strong": 4700,
            "active": true,
            "sell": "tt"
        },
        "981273jn19203nj123rg": {
            "id": 3,
            "strong": 3000,
            "active": true,
            "sell": "ti"
        }
    }
}]

Add the code of GSON format to JAVA Class:

import com.google.gson.annotations.SerializedName;
public class test_de {

/**
 * id : 1001
 * name : Super1
 * user : {"name":"The Super 1"}
 * items : {"987987M7812b163eryrt":{"id":1,"strong":456,"active":true,"sell":"te"},"90812bn120893juuh":{"id":2,"strong":4700,"active":true,"sell":"tt"},"981273jn19203nj123rg":{"id":3,"strong":3000,"active":true,"sell":"ti"}}

Why does the backend need to send you gibberish keys, rather than them just being an array, if the items themselves already have IDs? — Submersed, Jan 31 '18 at 19:51
Thanks @Submersed if with gibberish keys you mean 987987M7812b163eryrt, 90812bn120893juuh and 981273jn19203nj123rg is becouse is another id_numeric_string that the backend have. — LuDev, Jan 31 '18 at 20:10

You can use GSON. Just define

@SerializedName("items")
Map<String, Inner> items;

in your outer class where Inner is class like

public class Inner {
    private int id;
    private boolean active;
    private int strong;
    private String sell;
}

Or you can use a custom Gson JsonDeserializer.

Thanks, i will try this, anticipate i'm looking for something like this, that is, a simple java class that i can be able to call for fill a listview, not matter the quantity and don't matter the objects name. PD: i'm not to acquainted with custom Gson JsonDeserializer. – LuDev Jan 31 '18 at 20:05
Sorry this is actually not working, can't access to values – LuDev Mar 20 '18 at 21:10
