Android studio 下 soap的实现（调用天气接口）

首先附上我在实现过程中参考的两篇十分有用的文档：
1.https://www.cnblogs.com/zhangdongzi/archive/2011/04/19/2020688.html
2.https://trinitytuts.com/load-data-from-soap-web-service-in-android-application/
工具准备：
OPPO k3 Android （9.0）手机，http://www.webxml.com.cn 天气测试网站， Android studio 3.2开发环境
实现步骤：

1. 建立Android工程 增加输入，显示框和按钮
2. 下载：ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar 包
3. 把第二步下载的包拷贝到工程目录app/libs 下
4. 在Android studio 添加包到工程
5. 编写代码调用公开的网络天气接口验证工程代码。

具体实现：
1． 建立工程，输入，显示框和按钮 满足测试需要如图：

2.下载soap包 https://download.csdn.net/download/zz_mm/3946373 （要积分，我也找人要的）
3.复制到相应目录如图：

4.以添加第三方模块的方式添加到工程如图：

5.完成天气网站可支持省份接口的调用：如图

调用成功！
下面是简单的测试代码，如果你没有做过soap的话有的难度，但是只要遵循固定的调用顺序基本没有问题，在调试过程中遇到很多问题，不要慌，多搜基本都能解决，实在解决不了，歇一会儿明天在看就不一样了。
