Gson Parse Json with array with different object types

Question

How can I parse this JSON using Gson? I have an array with multiple object types and I don\'t know what kind of object I need to create to save this structure. I cannot cha

Try this code here:

public class Address {
    public String userId;
    public String address;
    // ...
}

public class Response {
    private HashMap tr;
    private int results;
    // ...
}

Usage:

String json = "{\n  \"tr\":\n  {\n    \"a\": {\n       \"userId\": \"112\"\n    },\n    \"b\": {\n       \"userId\": \"123\",\n       \"address\":\"street dummy\"\n    },\n    \"c\": {\n       \"userId\": \"154\"\n    }\n  },\n  \"results\":3\n}";

Response users = new Gson().fromJson(json, Response.class);

As you may see I needed to modify the structure:

{
  "tr":
  {
    "a": {
       "userId": "112"
    },
    "b": {
       "userId": "123",
       "address":"street dummy"
    },
    "c": {
       "userId": "154"
    }
  },
  "results":3
}

But unfortunately I don't get it managed to allow multiple keys. Right now I have no idea how to fix this.
