You should start by reading Android Docs. http://developer.android.com/reference/org/json/JSONObject.html — Sufian, Jun 09 '14 at 05:02

How can you identify it without a key name? Are you just looking for any field containing an object? — shmosel, Jun 09 '14 at 05:12
Without using any kind of library it will be difficult for you. But Jackson library may help in a easy way to solve this if you like. — Cyclops, Jun 09 '14 at 05:15

Json Object is just like a Map, you can iterate it like this:

    JSONObject parse = JSON.parseObject("");
    for (Map.Entry<String, Object> entry : parse.entrySet()) {
        System.out.println(entry.getKey() + "=" + entry.getValue());
    }

MY JSON object also contains another object.How can I detect inner object. – user2709752 Jun 09 '14 at 05:04
Just think you inner object as a map, and cast it to JSONObject. – lichengwu Jun 09 '14 at 05:13
