Dynamic JSON Model

Question

Here, I'm trying to parse this JSON Object into model. But I'm stuck here with the dynamic field names. Here is the example of the JSON Object

{
    "1": {
        "state": {
            "on": false,
            "bri": 0,
            "hue": 0,
            "sat": 0,
            "effect": "none",
            "xy": [
                0,
                0
            ],
            "ct": 0,
            "alert": "none",
            "colormode": "hs",
            "reachable": false
        },
        "type": "Extended color light",
        "name": "Hue Lamp 1",
        "modelid": "LCT001",
        "manufacturername": "Philips",
        "uniqueid": "00:17:88:01:00:f4:5a:aa-0b",
        "swversion": "5.23.1.13452"
    },
    "2": {
        "state": {
            "on": false,
            "bri": 254,
            "hue": 8000,
            "sat": 200,
            "effect": "none",
            "xy": [
                0.5469,
                0.3819
            ],
            "ct": 500,
            "alert": "none",
            "colormode": "hs",
            "reachable": true
        },
        "type": "Extended color light",
        "name": "Hue Lamp 2",
        "modelid": "LCT001",
        "manufacturername": "Philips",
        "uniqueid": "00:17:88:01:00:f4:5c:55-0b",
        "swversion": "5.23.1.13452"
    }
}

There are these field "1","2" and so on. How to parse this into model ? Can anybody help ?

Updated : All i want to achieve is getting this "1", "2" key value and the "name" field value in it. Thanks before !

You need to wrap json in one root element then use model like this

public class RootElement{
     private Map<String, DataInfo> rootElement;
} 

public class DataInfo {
     private State state= null;
     private String type= null;
    // all your field under 1, 2

}

And your json should look like this

        "rootElement": {

          "1": {
                "state": {
                 "on": false,
                "bri": 0,
                "hue": 0,
                "sat": 0,
                "effect": "none",
                "xy": [
                    0,
                    0
                ],
                "ct": 0,
                "alert": "none",
                "colormode": "hs",
                "reachable": false
            },
            "type": "Extended color light",
            "name": "Hue Lamp 1",
            "modelid": "LCT001",
            "manufacturername": "Philips",
            "uniqueid": "00:17:88:01:00:f4:5a:aa-0b",
            "swversion": "5.23.1.13452"
        },

      // other object
}

response().getRootElement().get(*).getName(). in this *, it said that need to fiil Object o. what is that ? – Tommy Wu Sep 26 '16 at 06:50
what i mean is when i'm trying to GET data from the API and add it into an arraylist, the code is like this right ? `List item = new ArrayList<>(); for (int i = 0; i < responsePhilipsLightses.size(); i++) { item.add(responsePhilipsLightses.get(i).getResponse().get(i).getName()); } ` – Tommy Wu Sep 26 '16 at 06:57
but between getResponse().get("*")‌.getName(), in this * section, it said it need to fill the object, so what is this object – Tommy Wu Sep 26 '16 at 07:00
response object will be your RootElement class object , you can then iterate over it to get 1,2 .. – Jekin Kalariya Sep 26 '16 at 08:01

@tommy wu , try this

JSONObject questionMark = new JSONObject("your string containing whole json object");
    Iterator keys = questionMark.keys();

    while(keys.hasNext()) {
        // loop to get the dynamic key
        String currentDynamicKey = (String)keys.next();

        // get the value of the dynamic key
        JSONObject currentDynamicValue = questionMark.getJSONObject(currentDynamicKey);

        // do something here with the value...
    }

where should i put this ? I'm using retrofit to get the API data – Tommy Wu Sep 26 '16 at 07:01
You shuld put this into the class where you are getting the above mentioned json object by using Retrofit. – Ashish Kumar Gupta Sep 26 '16 at 07:05
erm can u guide me through example ? im kinda confused about what u said – Tommy Wu Sep 26 '16 at 07:13
get Retrofit response as a JSONObject and apply above. – Mahendra Chhimwal Sep 26 '16 at 07:21
ermm. in the JSONObject, there is no string that contains whole JSON Object. so how's to do this ? – Tommy Wu Sep 26 '16 at 07:27
@tommy wu, How you are getting the above jsonobject from Retrofit? – Ashish Kumar Gupta Sep 26 '16 at 08:24
ermm. so now, that JSON Object is what I want to get. I get that response from the Postman. and now in Retrofit i want to get that JSON Object to get the "name" and the "id" key. the "id" is "1","2" and so on – Tommy Wu Sep 26 '16 at 08:32
