Android下应用WebService

?

在做项目时，应用了WCF，在传输数据时，首先把数据转换成字符串，这样，就会产生很多问题，例如：如果数据是出现一些特殊符号（？、#等）这样数据就会出错。现在我要扩展功能，发现WCF的最大弊端，WCF是不能传数据流的，也我是我的能力有限。最后还是决定把WCF换回WebService，在这里给大家一个小例子，供大家参考，有什么不懂的发邮件给我：

用WebService需要一个jar包，可以去官网上下：http://code.google.com/p/k/ksoap2-android/downloads/list

Main.java

package com.action;

import org.ksoap2.SoapEnvelope;

import android.content.DialogInterface;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class Main extends Activity implements OnClickListener {

	private EditText mEditText;
	private TextView mTextView;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

	public void onClick(View view) {
		//连接.net代码
		try {

			/*
			 * "http://tempuri.org/" 为命名空间,命名空间是.net默认的
			 * 通过SoapObject类 创建一个对象，以命名空间和要访问的方法名构造
			 */
			SoapObject request = new SoapObject(namespace,
					methodName);
			//添加传递的参数名称及值,这是城的参数名称是任意的，可以不与服务上的方法名称一至
			request.addProperty("name", "23");
			SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
					SoapEnvelope.VER11);
			envelope.dotNet = true;
			envelope.setOutputSoapObject(request);
//			envelope.bodyOut = request;
			HttpTransportSE htp = new HttpTransportSE(serviceUrl);
//			AndroidHttpTransport httpTransport = new AndroidHttpTransport(serviceUrl);
			// 要访问的命名空间+方法名,也就是别人说的ACTION
			htp.call(namespace+methodName, envelope);
//			httpTransport.call(null, envelope);
//			SoapPrimitive result = (SoapPrimitive) envelope.getResponse();
			String result = envelope.getResponse().toString();
			ShowDialog(result);
		} catch (Exception e) {
			e.printStackTrace();
			ShowDialog(e.getMessage());
		}

		/*

	}

	public void ShowDialog(String msg) {
		new AlertDialog.Builder(this).setTitle("提示").setMessage(msg)
				.setPositiveButton("OK", new DialogInterface.OnClickListener() {

	}
}

?我用的是.net服务，我对.net不太董，在这里就不写了，可以去参考别人的代码

在上面的命名空间，方法名，Action等信息都可以在我们用连接打开页面中找到，其中Action在进入方法中才能看到
