如何使用 Gson API 创建这个 JsonObject？

我在正确序列化/反序列化这个 json 对象时遇到了问题：

<前><代码>{ 系列：[{ 数据：[[长整型]，...]，标签：字符串 }, ... ], 选项：{ 鼠标：{轨迹：true}， x轴：{noTicks：10}，点：{显示：true}，行：{显示：true} } }

这是我尝试过的；然而，Gson 似乎不喜欢 fromJson，尽管它确实正确地执行了 toJson。

class JsonBlock {
    ArrayList<Series> series = new ArrayList();
    String options = "mouse:{track:true},"
                   + "xaxis:{noTicks:10},"
                   + "points:{show:true},"
                   + "lines:{show:true}";
    public String toString() { return String.format("series:%s,options:%s",series, options); }
}

class Series {
    ArrayList<Data> data = new ArrayList();
    String label = "";
    public Series(String label, Data d) { this.label = label; data.add(d); }
    public String toString() { return String.format("data:%s,label:%s", data, label); }
}

class Data {
    long date = -1;
    int qty = 0;
    public Data(long date, int qty) { this.date = date; this.qty = qty; }
    public String toString() { return date + "," + qty; }
}

任何提示或答案表示赞赏。谢谢：）

原文

I've been having trouble getting this json object to serialize/deserialize properly:

{
  series:[{
      data:[[long,int], ... ],
      label:String
  },
  ...
  ],
  options:{
      mouse:{track:true},
      xaxis:{noTicks:10},
      points:{show:true},
      lines:{show:true}
  }
}

Here is what I tried; however, Gson doesn't seem to like doing fromJson, although, it does correctly do toJson.

class JsonBlock {
    ArrayList<Series> series = new ArrayList();
    String options = "mouse:{track:true},"
                   + "xaxis:{noTicks:10},"
                   + "points:{show:true},"
                   + "lines:{show:true}";
    public String toString() { return String.format("series:%s,options:%s",series, options); }
}

class Series {
    ArrayList<Data> data = new ArrayList();
    String label = "";
    public Series(String label, Data d) { this.label = label; data.add(d); }
    public String toString() { return String.format("data:%s,label:%s", data, label); }
}

class Data {
    long date = -1;
    int qty = 0;
    public Data(long date, int qty) { this.date = date; this.qty = qty; }
    public String toString() { return date + "," + qty; }
}

Any hints or answers are appreciated. Thanks :)
