Android(安卓)调用.NET webservice

package com.fairyeye.simple;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;import android.widget.TextView;import android.widget.Toast;import org.ksoap2.SoapEnvelope;import org.ksoap2.serialization.SoapObject;import org.ksoap2.serialization.SoapSerializationEnvelope;import org.ksoap2.transport.HttpTransportSE;public class MiniSystemActivity extends Activity {/** Called when the activity is first created. */private EditText userName;private EditText userPass;private Button btnLogin;private Button btnClose;private TextView tv;final String SOAP_ACTION = "http://tempuri.org/HelloWorld";     private static final String METHOD_NAME = "HelloWorld";     private static final String NAMESPACE = "http://tempuri.org/";     private static final String URL = "http://10.0.2.2/webser/webtest.asmx"; @Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);btnLogin = (Button) findViewById(R.id.btnLogin);btnClose = (Button) findViewById(R.id.btnClose);userName = (EditText) findViewById(R.id.userName);userPass = (EditText) findViewById(R.id.userPass);tv = (TextView)findViewById(R.id.txtView);btnLogin.setOnClickListener(listener);call();}private OnClickListener listener = new OnClickListener() {public void onClick(View v) {// TODO Auto-generated method stubif (userName.getText().toString().trim().equals("222")&& userPass.getText().toString().trim().equals("222")) {Intent intent = new Intent();intent.setClass(MiniSystemActivity.this, testActivity.class);startActivity(intent);} else {Toast.makeText(MiniSystemActivity.this, "用户或密码错误！",Toast.LENGTH_LONG).show();}}};public void call() {try {SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);//request.addProperty("passonString", "Rajapandian"); //这个是传递参数的SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);envelope.dotNet = true;envelope.setOutputSoapObject(request);HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);androidHttpTransport.call(SOAP_ACTION, envelope);Object result = (Object) envelope.getResponse();tv.setText(result.toString()); } catch (Exception e) {System.out.println(e.getMessage());tv.setText(e.getMessage());}}}

---------------------------------以上实现了 Android内通过Ksoap包的方法调用了 .net webserivce中 helloworld 方法。

1.在ADT 虚拟机中 localhost/127.0.01是不行的。虚拟机中默认10.0.2.2为本地地址所以我们在本地的.NET webservice 如果为localhost/webser/webtest.asmx 在Android模拟器中为10.0.2.2/webser/webtest/asmx.（该问题亲自测试）

2.记得在AndroidManifest.xml 加入允许访问 Internet<uses-permission android:name="android.permission.INTERNET" />
