Question

我有一个关于如何在Android中使用JSON集成的问题。例如，我有一个登录页面，我希望使用SOAP webservices进行身份验证以进行导航。我想使用JSON集成，我该怎么做？有谁能够帮我？如果您有一个例子，请提供。

这是我在logcat中显示输出的代码。现在如何在模拟器上检索？

Android SDK包含JSON实现。您在body被格式化为JSON时提交请求。如果该请求被接受，您的服务将返回响应，其中响应的主体将采用JSON格式。之后，您只需通过声明JSON对象进行解析，如下所示：

JSONObject json = new JSONObject(rawJson);
