Using GSON to parse JSON

How do I parse this JSON using the GSON Library.

[
{
    "id": "1",
    "title": "None"
},
{
    "id": "2",
    "title": "Burlesque"
},
{
    "id": "3",
    "title": "Emo"
},
{
    "id": "4",
    "title": "Goth"
}
]

I have tried to do this

public class EventEntity{

    @SerializedName("id")
    public String id;

    @SerializedName("title")
    public String title;



    public String get_id() {
        return this.id;
    }

    public String get_title() {
        return this.title;
    }
}

JSONArray jArr = new JSONArray(result);
            //JSONObject jObj = new JSONObject(result);
            Log.d("GetEventTypes", jArr.toString());                

            EventEntity[] enums = gson.fromJson(result, EventEntity[].class);
            for(int x = 0; x < enums.length; x++){                  
                String id = enums[x].get_id().toString();
            }

So far I can get the id using get_id method but I cant seem to assign it to the string id. What is the proper way to go about this?

Your class EventEntity is correct, but in order to parse the JSON, you'd better do something like this:

Gson gson = new Gson();
Type listType = new TypeToken<List<EventEntity>>() {}.getType();
List<EventEntity> data = gson.fromJson(result, listType);

Then you'll have a List with all your EventEntity objects into the variable data, so you can access the values just with:

String id = data.get(i).get_id();
String title = data.get(i).get_title();
