Android通过调用Webservice实现手机号码归属地查询
此app的实现功能如图所示：
注：http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx是本文webservice的提供商
具体的用法见：http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx?op=getMobileCodeInfo
以下是 SOAP 1.2 请求和响应示例。所显示的占位符需替换为实际值。
POST /WebServices/MobileCodeWS.asmx HTTP/1.1Host: webservice.webxml.com.cnContent-Type: application/soap+xml; charset=utf-8Content-Length: length<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"> <soap12:Body> <getMobileCodeInfo xmlns="http://WebXml.com.cn/"> <mobileCode>string</mobileCode> <userID>string</userID> </getMobileCodeInfo> </soap12:Body></soap12:Envelope>
HTTP/1.1 200 OKContent-Type: application/soap+xml; charset=utf-8Content-Length: length<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"> <soap12:Body> <getMobileCodeInfoResponse xmlns="http://WebXml.com.cn/"> <getMobileCodeInfoResult>string</getMobileCodeInfoResult> </getMobileCodeInfoResponse> </soap12:Body></soap12:Envelope>
创建android工程MobileAddressQuery，并设置网络访问权限。
string.xml
<?xml version="1.0" encoding="utf-8"?><resources> <string name="hello">Hello World, MainActivity!</string> <string name="app_name">手机号码归属地查询</string> <string name="mobile">手机号码</string> <string name="button">归属地查询</string> <string name="error">查询失败</string></resources>
布局 main.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical" android:layout_width="fill_parent"android:layout_height="fill_parent"><TextView android:layout_width="fill_parent"android:layout_height="wrap_content" android:text="@string/mobile" /><EditText android:layout_width="fill_parent"android:layout_height="wrap_content" android:id="@+id/mobile" /><Button android:layout_width="fill_parent"android:layout_height="wrap_content" android:text="@string/button"android:onClick="query" /><!-- 指定button的响应方法为query --><TextView android:layout_width="fill_parent"android:layout_height="wrap_content" android:id="@+id/textView" /></LinearLayout>
在src目录下创建sop12.xml，并将网址文档中提供的代码复制其中，如下
<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"> <soap12:Body> <getMobileCodeInfo xmlns="http://WebXml.com.cn/"> <!-- $mobile只是展示如此，在程序调用此xml文件后会将用户输入的手机号码代替 --> <mobileCode>$mobile</mobileCode> <userID></userID> </getMobileCodeInfo> </soap12:Body></soap12:Envelope>业务类：AddressService
注意访问目标地址是：
http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx
可以有协议中得到。
