使用 Klaxon JSON for Android 如何将以下 JSON 放入 ListView？

Question

我正在研究如何使用 Klaxon 将我的 JSON 放入 LIstView 的数组中。这与 Java 不同，原因有两个。是 Kotlin 和 Klaxon。

以下是各州城镇的一系列邮编和信息。我正在通过 Fuel 提取它，我可以将它放入 Klaxon 以将部分对象读入文本字段，但我想构建一个列表，其中每个对象都有自己的行。想知道如何从 A 点喇叭进入列表 B 点。

不知道该怎么做。

{"towns":[{"zip":"02052","City":"Medfield","State":"MA","lat":"42.178","Long":"-71.3059" },{"zip":"02054","City":"Millis","State":"MA","lat":"42.1677","Long":"-71.3601"},{"zip": "02081","City":"Walpole","State":"MA","lat":"42.1429","Long":"-71.2571"},{"zip":"02030","City" :"Dover","State":"MA","lat":"42.2341","Long":"-71.2861"},{"zip":"02056","City":"Norfolk","State ":"MA","lat":"42.1185","Long":"-71.3287"},{"zip":"02032","City":"East Walpole","State":"MA","lat":"42.1548","Long":"-71.2164"},{"zip":"02062","City":"Norwood","State": "MA","lat":"42.1855","Long":"-71.2022"},{"zip":"02071","City":"南 Walpole","State":"MA","lat":"42.105","Long":"-71.2705"},{"zip":"01770","City":"Sherborn","State": "MA","lat":"42.233","Long":"-71.3814"}

Answer 1

您需要有一个对象来描述您的格式并使用您的库将其从 JSON 转换（不知道 Klaxon，但 GSON 将如示例所示）

单独文件中的模型

public class Model {
public String zip, City, State, lat, Long;
}
public class ModeList {
public Model[] towns;
}

那么你需要你的价值观：

List<Model> listOfModel = new Gson().fromJson(yourJsonAsStringHere);

要在 ListView 中显示，您可以使用模型列表来获取元素的数量，并让每个元素显示一个值。

Klaxon 非常简单，您可以从 github https://github.com/cbeust/klaxon 将示例检入自述文件中

使用 kotlin，您甚至不需要提前构建类型。
