问题描述

我有一个code，这使得通过WWW，tempuri.org所提供的Web服务的调用。
当我试图运行应用程序，应用程序意外停止，并显示信息 - 不幸的是，MyTest的已经停止。这里是我的java文件 -

I have a code, which makes a call to the web service provided by www,tempuri.org. While I am trying to run the application, the application is stopping unexpectedly and showing the message - "Unfortunately, MyTest has stopped".. Here is my java file -

MainActivity.java： -

MainActivity.java :-

package com.example.mytest;


import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;

import org.ksoap2.transport.HttpTransportSE;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity {
    public static final String SOAP_ACTION = "http://tempuri.org/CelciusToFarenheit";
    public static final String METHOD_NAME = "CelciusToFarenheit";
    public static final String NAMESPACE= "http://tempuri.org/";
    public static final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
    TextView tv;
    SoapEnvelope se;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv= (TextView) findViewById(R.id.TextView01);

        SoapObject Request=new SoapObject(NAMESPACE,METHOD_NAME);
        Request.addProperty("Celcius","32");
        SoapSerializationEnvelope sse = new SoapSerializationEnvelope (se.VER11);
        sse.dotNet=true;
        sse.setOutputSoapObject(Request);
        HttpTransportSE abt = new HttpTransportSE(URL);
        try
        {
            abt.call(SOAP_ACTION,se);
              SoapObject resultString=(SoapObject)sse.getResponse();   
              String resultData=resultString.getProperty(0).toString();

            tv.setText("Status :"+resultString);
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }





    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

activity_main.xml中： -

activity_main.xml :-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/TextView01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

</RelativeLayout>

的logcat的如下 -

我是新与Android开发Web服务。能否请你建议我，有什么该怎么做？

I am new to develop web services with android. Can you please suggest me, what to do with this?

推荐答案

尼尔默尔的回答上面的伎俩我。但是，我不得不更新行动，命名如下：

Nirmal's answer above did the trick for me. However, I had to update action and namespace as follows:

private static final String SOAP_ACTION = "http://www.w3schools.com/webservices/CelsiusToFahrenheit";
private static final String NAMESPACE = "http://www.w3schools.com/webservices/";

我想通了正确的价值观应该是什么：

I figured out what the correct values should be by:

1. 将Web服务页面： http://www.w3schools.com/ Web服务/ tempconvert.asmx

点击服务原文链接： http://www.w3schools.com /webservices/tempconvert.asmx?WSDL

搜索字符串（不区分大小写）行动，并在该XML命名，然后使用值它们有

Searching for the strings (case-insensitive) "action" and "namespace" in that xml, and then use the values they have
