Android使用ksoap2包访问webservice接口

Android本身没有集成访问webservice的相关api，需要我们引用第三方的包，现在一般用的是 ksoap2.jar这个包，大小不足200K，非常轻量级， 点击此处下载jar包。使用时将jar包放进android项目的libs文件中即可。 下面是使用ksoap2获取电话号码地区的一个简单例子：

package com.yeetrack.mynumberquery;

import java.io.IOException;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.xmlpull.v1.XmlPullParserException;

import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.app.Activity;
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;

    private Handler handler = new Handler()

        {
            Bundle bundle = msg.getData();
            String result = bundle.getString("result");
            if(result != null)
                resultView.setText(result);
        }

                    else    
                    {
                        resultView.setText("加载中...");
                        new Thread(runnable).start();
