android调用WebService接口

一个电话号码在线查询的简单例子,android调用webService接口

 

package com.example.webservice;

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

import android.app.Activity;
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;

public class MainActivity extends Activity {
	private EditText phoneSecEditText;
	private TextView resultView;
	private Button queryButton;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		phoneSecEditText = (EditText) findViewById(R.id.phone_sec);
		resultView = (TextView) findViewById(R.id.result_text);
		queryButton = (Button) findViewById(R.id.query_btn);

		queryButton.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				// 手机号码（段）
				String phoneSec = phoneSecEditText.getText().toString().trim();
				// 简单判断用户输入的手机号码（段）是否合法
				if ("".equals(phoneSec) || phoneSec.length() < 7) {
					// 给出错误提示
					phoneSecEditText.setError("您输入的手机号码（段）有误！");
					phoneSecEditText.requestFocus();
					// 将显示查询结果的TextView清空
					resultView.setText("");
					return;
				}
				// 查询手机号码（段）信息
				getRemoteInfo(phoneSec);
			}
		});
	}

	/**
	 * 手机号段归属地查询
	 * 
	 * @param phoneSec
	 *            手机号段
	 */
	public void getRemoteInfo(String phoneSec) {
		// 命名空间
		String nameSpace = "http://WebXml.com.cn/";
		// 调用的方法名称
		String methodName = "getMobileCodeInfo";
		// EndPoint
		String endPoint = "http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx";
		// SOAP Action
		String soapAction = "http://WebXml.com.cn/getMobileCodeInfo";

		// 指定WebService的命名空间和调用的方法名
		SoapObject rpc = new SoapObject(nameSpace, methodName);

		// 设置需调用WebService接口需要传入的两个参数mobileCode、userId
		rpc.addProperty("mobileCode", phoneSec);
		rpc.addProperty("userId", "");

		// 生成调用WebService方法的SOAP请求信息,并指定SOAP的版本
		SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
				SoapEnvelope.VER10);

		envelope.bodyOut = rpc;
		// 设置是否调用的是dotNet开发的WebService
		envelope.dotNet = true;
		// 等价于envelope.bodyOut = rpc;
		envelope.setOutputSoapObject(rpc);

		HttpTransportSE transport = new HttpTransportSE(endPoint);
		try {
			// 调用WebService
			transport.call(soapAction, envelope);
		} catch (Exception e) {
			e.printStackTrace();
		}

		// 获取返回的数据
		SoapObject object = (SoapObject) envelope.bodyIn;
		// 获取返回的结果
		String result = object.getProperty(0).toString();

		// 将WebService返回的结果显示在TextView中
		resultView.setText(result);
