JsonArray和Gson(JsonArray and Gson)

我正在使用的JSON库是Gson。 我很难制定一个有效的数据类型来表示以下JSON字符串:

{  
   "latestoffers": [
      {
         "id": "4qXleunwNMCKi8M0q0CuMa",
         "price": "534.99",
         "firstrecorded_at": 1377808800,
         "lastrecorded_at": 1382862800,
         "seller": "Newegg",
         "availability": "In stock. [BBX: Buy Box]",
         "currency": "USD"
      },
      {
         "id": "4xTIQAPySG68IS0CGyOuyO",
         "price": "582.41",
         "firstrecorded_at": 1380725000,
         "lastrecorded_at": 1382862800,
         "seller": "Beach Audio",
         "currency": "USD"
      },
      {
         "id": "5nW67R2V4CwmE8cwaWsawe",
         "price": "578.04",
         "firstrecorded_at": 1379524200,
         "lastrecorded_at": 1379998900,
         "seller": "Beach Audio",
         "currency": "USD"
      }
      ],
   "offers_count": 6,
   "name": "newegg.com",
   "recentoffers_count": 2,
   "sku": "N82E16834216463",
   "url": "http://www.newegg.com/Product/Product.aspx?Item=N82E16834216463"
}

我的数据类(到目前为止)如下,它是方法getOfferData() ,我不知道如何完成。 我也不确定JsonArray是否适合使用JSON元素?

static class LatestOffers {

    Integer offers_count;
    String name;
    Integer recentoffers_count;
    String sku;
    String url;

    java.util.List<JsonArray> getOfferData() {

        List<JsonArray> list = new ArrayList<JsonArray>();
        // how do I get parse the 'id', 'price', 'firstrecorded_at' etc. to add them to the ArrayList?
          return list;
    }

    Integer getOffers_count() {
        return offers_count;
    }

    String getName() {
        return name;
    }

    Integer getRecentoffers_count() {
        return recentoffers_count;
    }

    String getSku() {
        return sku;
    }

    String getUrl() {
        return url;
    }
}

有什么帮助吗? 谢谢。

结果我不必要地使事情变得复杂,这按预期工作:

static class LatestOffers {
        List<Offer> latestoffers;

        List<Offer> getOffer() {
            return latestoffers;
        }
    }

    static class Offer {

        private String id;
        private String price;
        private long firstrecorded_at;
        private long lastrecorded_at;
        private String seller;
        private String availability;
        private String currency;

        String getId() {
            return id;
        }

        String getPrice() {
            return price;
        }

        long getFirstrecorded_at() {
            return firstrecorded_at;
        }

        long getLastrecorded_at() {
            return lastrecorded_at;
        }

        String getSeller() {
            return seller;
        }

        String getAvailability() {
            return availability;
        }

        String getCurrency() {
            return currency;
        }

    }

感谢所有回答的人,我接受了user2762451的回答,因为他是第一个建议使用另一个类来提供数据的人。


The JSON library I'm using is Gson. I'm having difficulty formulating a functioning data type to represent the following JSON string:

{  
   "latestoffers": [
      {
         "id": "4qXleunwNMCKi8M0q0CuMa",
         "price": "534.99",
         "firstrecorded_at": 1377808800,
         "lastrecorded_at": 1382862800,
         "seller": "Newegg",
         "availability": "In stock. [BBX: Buy Box]",
         "currency": "USD"
      },
      {
         "id": "4xTIQAPySG68IS0CGyOuyO",
         "price": "582.41",
         "firstrecorded_at": 1380725000,
         "lastrecorded_at": 1382862800,
         "seller": "Beach Audio",
         "currency": "USD"
      },
      {
         "id": "5nW67R2V4CwmE8cwaWsawe",
         "price": "578.04",
         "firstrecorded_at": 1379524200,
         "lastrecorded_at": 1379998900,
         "seller": "Beach Audio",
         "currency": "USD"
      }
      ],
   "offers_count": 6,
   "name": "newegg.com",
   "recentoffers_count": 2,
   "sku": "N82E16834216463",
   "url": "http://www.newegg.com/Product/Product.aspx?Item=N82E16834216463"
}

My data class (so far) is as follows, it's the method getOfferData() that I don't how to complete. I'm also not certain whether JsonArray is the appropriate JSON element to be using?

static class LatestOffers {

    Integer offers_count;
    String name;
    Integer recentoffers_count;
    String sku;
    String url;

    java.util.List<JsonArray> getOfferData() {

        List<JsonArray> list = new ArrayList<JsonArray>();
        // how do I get parse the 'id', 'price', 'firstrecorded_at' etc. to add them to the ArrayList?
          return list;
    }

    Integer getOffers_count() {
        return offers_count;
    }

    String getName() {
        return name;
    }

    Integer getRecentoffers_count() {
        return recentoffers_count;
    }

    String getSku() {
        return sku;
    }

    String getUrl() {
        return url;
    }
}

Any assistance, please? Thank you.

EDIT

Turns out I was unnecessarily complicating things, this works as intended:

static class LatestOffers {
        List<Offer> latestoffers;

        List<Offer> getOffer() {
            return latestoffers;
        }
    }

    static class Offer {

        private String id;
        private String price;
        private long firstrecorded_at;
        private long lastrecorded_at;
        private String seller;
        private String availability;
        private String currency;

        String getId() {
            return id;
        }

        String getPrice() {
            return price;
        }

        long getFirstrecorded_at() {
            return firstrecorded_at;
        }

        long getLastrecorded_at() {
            return lastrecorded_at;
        }

        String getSeller() {
            return seller;
        }

        String getAvailability() {
            return availability;
        }

        String getCurrency() {
            return currency;
        }

    }

Thank you to all who answered, I'm accepting the answer of user2762451 as (s)he was the first to suggest the use of another class for the Offer data.

最满意答案

NSSegmentedControl用于分段控件,并使用tabless NSTabView在视图之间切换。 如果它在你的应用中有意义,你甚至可以将它们绑定到相同的用户默认值,并且在不写一行代码的情况下实现它。


Use NSSegmentedControl for the segmented control, and a tabless NSTabView to switch between views. If it makes sense in your app, you could even bind both to the same user default and implement this without writing a single line of code.
