android - 使用数组改造解析 json 对象

Question

我正在尝试使用改造 2.1.0 解析下一个 json 对象，但我不知道为什么 data 字段中没有任何数据，它始终为空。

{
  "status": "OK",
  "message": "Upload succesfull",
  "data": [
    {
      "channel": "madrid",
      "date": "20161212221",
      "metadata": {
        "id": "tvmadrid",
        "channel_id": "tvmadrid.com",
        "channel_name": "mad",        
      },
      "promos": []
    },
    {
      "channel": "barca",
      "date": "20161233232",
      "metadata": {
        "id": "tvbarca",
        "channel_id": "tvbarca.com",
        "channel_name": "barca",  
      },
      "promos": []
    }
  ]
}

我的模型类在这里。

TvChannel

public class TvChannel {
private String status;
private String message;
private Data[] data;

public String getStatus() {
    return status;
}

public void setStatus(String status) {
    this.status = status;
}

public String getMessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;
}



public Data[] getData() {
    return data;
}

public void setData(Data[] data) {
    this.data = data;
}


@Override
public String toString() {
    return    "status " + status + "\n"
            + "message " + message + "\n"
            + "Data " + data.toString();
}

这是一个调用API的方法

public void getTvChannel(User user, MultipartBody.Part body) {

    //user.getData().getAutenticate(),

    Call<TvChannel> callTvChannel = getAPI().listTvChannel(user.getData().getAutenticate(), body);
    callTvChannel.enqueue(new Callback<TvChannel>() {
        @Override
        public void onResponse(Call<TvChannel> call, Response<TvChannel> response) {
            if (response.isSuccessful()) {




                Log.d(TAG, "body to string: " + response.body().getStatus());

                TvChannel tvChannel = response.body();



                ArrayList<Data> datas = new ArrayList<Data>(Arrays.asList(response.body().getData()));

                Log.d(TAG + " getTvChannel ", " onResponse: status: " + tvChannel.getStatus() + "  message: " + tvChannel.getMessage() );

                for (Data data : datas) {
                    Log.d(TAG,data.toString());
                }

            } else {
                Log.d(TAG + " getTvChannel", " onResponse " + "Error Code " + response.code());
            }
        }

        @Override
        public void onFailure(Call<TvChannel> call, Throwable t) {
            Log.d(TAG + " getTvChannel ", " onFailure " + " Didn't work " + t.getMessage() + " " + t.getCause() + " \n" + Arrays.toString(t.getStackTrace()));


        }
    });
}

提前致谢。

您不需要关注....只需调用 tvChannel.getData()

ArrayList<Data> datas = new ArrayList<Data>(Arrays.asList(response.body().getData()));
