请帮我解决这个问题。

看下面这个例子，我想在列表视图中获取这些数据。我们该怎么做？

{"Afpak":{"id":1,"race":"hybrid","flavors":["Earthy","Chemical","Pine"],"effects":{"positive":["Relaxed","Hungry","Happy","Sleepy"],"negative":["Dizzy"],"medical":["Depression","Insomnia","Pain","Stress","Lack of Appetite"]}},"African":{"id":2,"race":"sativa","flavors":["Spicy/Herbal","Pungent","Earthy"],"effects":{"positive":["Euphoric","Happy","Creative","Energetic","Talkative"],"negative":["Dry Mouth"],"medical":["Depression","Pain","Stress","Lack of Appetite","Nausea","Headache"]}}}

你有没有尝试过？
检查这个库：github.com/google/gson 你可以用它来解析 json 到 java 对象。

【解决方案1】：

您可以轻松地进行解析，首先您必须安装AwesomePojoGenerator。使用AwesomePojoGenerator将上述json生成模型类，然后使用google的GSON库进行解析。

OutputClass outputClass=new Gson().fromJson(jsonString,OutputClass.class)

【解决方案2】：

您是否有任何列表视图模板要显示，因为您无法在列表视图中的正常迭代中显示这些值，因为迭代 json 数组和 json 对象与获取数据不同。

【解决方案3】：

上面这个是 JsonObject 但你需要一个 JsonArray 来在 listview 中解析它。

[{"id":1,"race":"hybrid","flavors":["Earthy","Chemical","Pine"],"effects":{"positive":["Relaxed","Hungry","Happy","Sleepy"],"negative":["Dizzy"],"medical":["Depression","Insomnia","Pain","Stress","Lack of Appetite"]}},{"id":2,"race":"sativa","flavors":["Spicy/Herbal","Pungent","Earthy"],"effects":{"positive":["Euphoric","Happy","Creative","Energetic","Talkative"],"negative":["Dry Mouth"],"medical":["Depression","Pain","Stress","Lack of Appetite","Nausea","Headache"]}}]

请修复您的 json 并在 api 调用中将其解析为 Jsonarray

我已经编辑了 json ，你需要像上面这样的 jsonarray 。你必须管理你的领域，特别是 JsonObject。
