Android studio 下 soap的實現（調用天氣接口）

首先附上我在實現過程中參考的兩篇十分有用的文檔：
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/
工具準備：
OPPO k3 Android （9.0）手機，http://www.webxml.com.cn 天氣測試網站， Android studio 3.2開發環境
實現步驟：

1. 建立Android工程 增加輸入，顯示框和按鈕
2. 下載：ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar 包
3. 把第二步下載的包拷貝到工程目錄app/libs 下
4. 在Android studio 添加包到工程
5. 編寫代碼調用公開的網絡天氣接口驗證工程代碼。

具體實現：
1． 建立工程，輸入，顯示框和按鈕 滿足測試需要如圖：

2.下載soap包 https://download.csdn.net/download/zz_mm/3946373 （要積分，我也找人要的）
3.複製到相應目錄如圖：

4.以添加第三方模塊的方式添加到工程如圖：

5.完成天氣網站可支持省份接口的調用：如圖

調用成功！
下面是簡單的測試代碼，如果你沒有做過soap的話有的難度，但是隻要遵循固定的調用順序基本沒有問題，在調試過程中遇到很多問題，不要慌，多搜基本都能解決，實在解決不了，歇一會兒明天在看就不一樣了。
