Parsing json with android

Hi I want to parse this json:

[{
    "codError": 0,
    "msg": "OK"
}, {
    "id": 1,
    "role": {
        "id": 4,
        "name": "Super",
        "description": "Roling.",
        "rights": [],
        "superuser": true,
        "active": true,
        "optimisticLock": 0
    },
    "now": null,
    "points": [],
    "firstName": null,
    "lastName": null,
    "loginName": "admin",
    "password": null,
    "connected": true,
    "active": true,
    "optimisticLock": null
},
["U4"]
]

I want to get role id that is 4, the loginName that is admin and the value of the array U4.

Here is how I am trying to do the parse:

     // Role node is JSON Object
                    JSONObject role = getJSONObject(TAG_ROLE);
                    String role_id = role.getInt(TAG_ROLE_ID);
                    String loginName = getJSONObject(TAG_LOGINNAME);

how can I get U4 value? Thank you very much

Why should we do parsing of JSON if you are provided a ready made tool to parse a JSON and give you a complete hierarchy of Java classes???

Right??

Take a look at JsonSchema 2 Pojo site.

Provide your JSON input/output there. Select appropriate options like

Source type: JSON
Annotation style: GSON

Enable following 3 options

  1. Generate builder methods
  2. Use primitive types
  3. Use long integers

Select Jar button and you are done with.

Note

Please validate your JSON first.

First of all, the U4 doesn't seems JSON correct. I would have write it like:

{
  "your array":["U4"]
}

then use the method to get your array

JSONArray array = jsonObj.getJSONArray("your array");

then you can access the values on your JSONArray by iterating over it, like that

for (int i = 0; i < array.length(); i++) {
  array.getJSONObject(i);
}

Hope I help

Try out as below:

JSONArray arry=new JSONArray("yourjsonstring");
for(int i=0;i<arry.length();i++)
 {
      JSONObject obj=arry.getJSONObject(i);
     String role=obj.getString("role");
     JSONObject obj2=new JSONObject(role);
      String id=obj2.getString("id");
     JSONArray array =obj.getJSONArray("U4");
 }

Hope this helps you.

{ represents the Jsonobject and [ represents the jsonarray

Parse like this to get the role_id loginName from your json

 JSONArray jsonarr =new  JSONArray(yourstring);
 JSONObject jobj=jsonarr.getJSONObject(1);
 JSONObject role =jobj.getJSONObject("role");
 String role_id = role.getInt("id");
 String loginName=jsonarr.getString("loginName");
