本文介绍如何使用 Android 第三方插件 KSOAP2 解析从 WebService 接口返回的 Dataset 数据。提供了完整的 KSOAPHelper 类代码示例，演示了如何初始化、设置 SOAP 对象并获取解析后的数据。

主题：Android项目中ksopa2访问标准webservice接口，若返回数据为一般字符串或者字符串数组则相对简单，网上大把，若是dataset，网上也有很多关于用Java把返回结果转为xml文件的，但觉得那样会多做很多工作，担心影响手机用户体验，研究了一下午，也不算难，只是解析麻烦点，见代码

一、返回的结果Dataset集，如图：

二、KsoapHelper网络请求类

Android常用第三方插件Ksoap2一般用法就不介绍了，可自行百度了解，下面是我的调试解析类，可解析成功运用到项目中去：

三、上述接口改返回结果为Json字符串后处理

本想叫后端哥们修改结果，用简单http+json方式，我就用原有项目框架做起来更快，而不用再整合ksoap2进项目，也不需要解析复杂对象，那意味着他不要用标准webservice接口，而用简单VS中一般处理程序通过http协议在浏览器直接输出结果即可，没想到，他只是将结果json序列化返回给我。不敢再要求，只好，仍用ksoap，只是返回结果为json字符串，相当于string处理了，而不是复杂Dataset。修改上述KsoapHelper类中获取数据方法GetResult的返回结果，即直接返回获取到string字符串即可，之后将String转为json即可。
