好吧，我正试图从Weather Underground的JSON文件中为Android应用程序输出一些数据。我需要的是当天以及未来10天的当前温度和条件。提供的JSON数据给出了10天的展望，但我不知道如何分别解析每一天。而且，我甚至在试图将温度和条件转换为单个字符串输出时遇到了麻烦。
这是JSON集：

}我想，获取每天预测的最好方法可能是在JSON集上运行一个循环，然后只打印对应于每天的"周期"。I、 然而，我不知道如何用JSON将上述温度和预测数据打印到for循环设置的参数中。
如果有人能帮我弄清楚如何获得当天的天气预报，我会很高兴的。但如果我能以任何其他方式得到启发，请告诉我。谢谢
我看到错误，你试图获取JsonArray而不是JsonObject，以验证你可以使用下一页来查看你的jsonhttp://www.jsoneditoronline.org/
您更改了代码。这是我的密码。
