我如何在Android中使用Gson和Regetfit从深度嵌套的json对象解析字段？

Question

我有一个独特的情况，我必须从JSON的深度嵌套对象中获得某些时间。这有点复杂，我找不到一个解决方案，所以寻找解决这个问题的想法和方法

[{
        "mySpaceId": 73220,
        "myBuildingId": 14019,
        "myFloorId": 10569,
        "myFloorNumber": "4",
        "myFloorName": "4th Floor",
        "spaceName": "My Room 4",
        "capacity": 5,
        "type": "huddle",
        "busyAt": []
    },
    {
        "mySpaceId": 73219,
        "myBuildingId": 14019,
        "myFloorId": 10569,
        "myFloorNumber": "4",
        "myFloorName": "4th Floor",
        "spaceName": "My room 5",
        "description": null,
        "capacity": 4,
        "type": "huddle",
        "timeZone": "America/New_York",

        "busyAt": [{
            "from": "2019-06-07T23:00:00+0000",
            "to": "2019-06-07T23:15:00+0000",
            "events": [{
                "id": "109142028",
                "series_id": null,
                "recurrence_id": null,
                "uid": "ABCDE",
                "space_id": 73219,
                "start": {
                    "date_time": "2019-06-07T19:00:00-0400",
                    "time_zone": "America/New_York"
                },
                "end": {
                    "date_time": "2019-06-07T19:15:00-0400",
                    "time_zone": "America/New_York"
                },
                "started_at": "2019-06-07T19:00:00-0400",
                "ended_at": "2019-06-07T19:15:00-0400"
            }]
        }]
    }
]

 public List<BusyAt> getBusyAt() {
        return busyAt;
    }

    public void setBusyAt(List<BusyAt> busyAt) {
        this.busyAt = busyAt;
    }

是否有一种方法可以在这个级别检索started_at，并以8:00 am的格式解析日期和时间？在我的代码中使用它。

你知道怎么做吗？谢了！请让我知道，如果这是混淆或需要更多的澄清，很高兴张贴更多的代码。

Answer 1

您必须这样做：

JSONArray array = new JSONArray(result);
for (int i = 0; i < array.length(); ++i) {
JSONObject jObj = array.getJSONObject(i);

String busyAt = jObj.getString("busyAt");
// convert it to json array 
JSONArray busyAtArray = new JSONArray(busyAt)
String endedAt = busyAtArray.getJSONObject(0).getString("ended_at")
// convert the string and get the time from it

}

我希望你从中得到了大致的想法。这段代码肯定可以用更好的方式编写。
