OK~~接着前面写,这次介绍的是android调用.net的带soapheader的webservice,

布局文件很简单就一个button,网上有很多教程讲了android怎么调用webservice,好像带soapheader的很少~~好吧。。那就开始吧。。首先我们需要一个jar文件~~可以去网上搜ksoap2,我这里用的是ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar，具体代码见下面。。给出部分注释~~

package Taling.ChangePwd;

import android.app.Activity;
import android.os.Bundle;
import org.kxml2.kdom.Element;
import org.kxml2.kdom.Node;

import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

public class ChangePwdMain extends Activity {
	private Button okButton;
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		
		okButton = (Button) this.findViewById(R.id.btnLogin);
		okButton.setOnClickListener(new Button.OnClickListener() {
			@Override
			public void onClick(View v) {
				  getInfo();  
			}
		});
	}
//命名空间
	private static final String NAMESPACE = "http://taling.hnie.edu.cn/";
	private static String URL = "http://taling.hnie.edu.cn/sljchangepwd/changepwdservice.asmx";
//调用的方法名
	private static final String METHOD_NAME = "UpdateUser";
//此处是命名空间+方法名
	private static String SOAP_ACTION = "http://taling.hnie.edu.cn/UpdateUser";
	private SoapPrimitive detail;
	public void getInfo() {//主要代码在这里
		try {
			SoapObject rpc = new SoapObject(NAMESPACE, METHOD_NAME);
//此处2个propertyinfo,是updateuser方法所需的参数，代码下面贴出asmx代码
		    PropertyInfo pi = new PropertyInfo(); 
		    pi.setName("uid");  
		    pi.setValue("24058");               
		    rpc.addProperty(pi);
		    pi = new PropertyInfo(); 
		    pi.setName("password");  
		    pi.setValue("321");               
		    rpc.addProperty(pi);
		    //soapheader在这里
			 Element[] header = new Element[1];
			   header[0] = new Element().createElement(NAMESPACE, "MySoapHeader");

			   Element username = new Element().createElement(NAMESPACE, "Admin");
			   username.addChild(Node.TEXT, "这里你填的");
			   header[0].addChild(Node.ELEMENT, username);
			   Element pass = new Element().createElement(NAMESPACE, "Password");
			   pass.addChild(Node.TEXT, "这里你填的");
			   header[0].addChild(Node.ELEMENT, pass);
			   
			
			SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
			envelope.headerOut = header;
			envelope.bodyOut = rpc;
			envelope.dotNet = true;
			envelope.setOutputSoapObject(rpc);
			HttpTransportSE ht = new HttpTransportSE(URL);
			ht.call(SOAP_ACTION, envelope);
//此处如果用soapobject会报错
			detail =(SoapPrimitive) envelope.getResponse();
			Toast.makeText(this, detail.toString(), Toast.LENGTH_LONG).show();
			return;
		} catch (Exception e) {
			Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
		}
	}
    	
    }

上面代码header[0] = new Element().createElement(NAMESPACE, "MySoapHeader"); 此处的MySoapHeader与上面asmx里的MySoapHeader要相同。。。OK。。。就到这吧。。希望对您有帮助~~
