I have this Json File:
{
"code": "#0",
"data": {
"list": [
"Chris",
"Matt"
],
"time": 1453318488122
},
"millis": "1453492643260"
}
In Java using Gson how do I access the "data" part, then "list" and turn it into an ArrayList? I have tried looking online and they are all showing things way too complicated for what I want, like serializing a class into Json. I don't want that.. How do I access "List" array inside of "data" object and put into an ArrayList?
JsonObject fullObject = new JsonParser().parse(yourFileData).getAsJsonObject();
JsonObject data = fullObject.getAsJsonObject('data');
JsonArray dataList = data.getAsJsonArray('list');
From there you can use dataList and iterate the elements.
You can serialize/deserialize such JSON without any additional adapter classes if you define a class like this one.
class MyPojo {
String code;
long millis;
Data data;
static class Data {
List<String> list;
long time;
}
}
(+ eventually @SerializedName annotations if your strategy requires them)
