我正在尝试将我的应用程序连接到我在ASP中创建并且当前正在运行的 Web 服务localhost。该应用程序正在尝试访问Coordonate接受 3 个整数的方法。

我已经提供了代码和LogCat。我不得不提一下，我是 Web 服务的新手。

任何帮助将不胜感激！干杯!

代码： 

package Dan.Denver.Nuggets.googleMaps;

import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.SeekBar;

import android.widget.TextView;

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

public class SlideBar extends Activity
{
SeekBar seekBar;
TextView textView;
Button sendButton;

private static final String SOAP_ACTION = "http://tempuri.org/Coordonate";
private static final String METHOD_NAME = "Coordonate";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://localhost:49934/Service1.asmx";

SoapObject request;
SoapSerializationEnvelope soapEnvelope;

SoapPrimitive rezultat;

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.slidebar);
    textView = (TextView)findViewById(R.id.textView); 
    sendButton = (Button)findViewById(R.id.bSB);

    seekBar = (SeekBar)findViewById(R.id.sbSB);
    seekBar.setMax(100);
    seekBar.setProgress(1);

    seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() 
    {   
        public void onStopTrackingTouch(SeekBar seekBar)
        {
            // TODO Auto-generated method stub
        }

        public void onStartTrackingTouch(SeekBar seekBar)
        {
            // TODO Auto-generated method stub
        }

        public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) 
        {
            textView.setText(String.valueOf(progress + "%"));
//              if(progress >= 25 && progress < 50)
//                  textView.setTextColor(R.color.Yellow);
//              else if(progress >= 50 && progress < 75)
//                  textView.setTextColor(R.color.Orange);
//              else if(progress >= 75 && progress <= 100)
//                  textView.setTextColor(R.color.Red);
//              else 
//                  textView.setTextColor(R.color.Green);   
        }
    });

    sendButton.setOnClickListener(new View.OnClickListener() 
    {   
        public void onClick(View v) 
        {
            // TODO Auto-generated method stub
            //Toast.makeText(getBaseContext(), "Drumul este congestionat in proportie de "+textView.getText().toString(), Toast.LENGTH_LONG).show();
            request = new SoapObject(NAMESPACE, METHOD_NAME);
            request.addProperty("latitudine", Main.latitudine);
            request.addProperty("longitudine", Main.longitudine);
            request.addProperty("procentTrafic", seekBar.getProgress());

            soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            soapEnvelope.dotNet = true;
            soapEnvelope.setOutputSoapObject(request);

            transport = new HttpTransportSE(URL);
            try
            {
                transport.call(SOAP_ACTION, soapEnvelope);
                rezultat = (SoapPrimitive)soapEnvelope.getResponse();
                Toast.makeText(getBaseContext(), rezultat.toString(), Toast.LENGTH_LONG).show();
            }
            catch(Exception e)
            {
                e.printStackTrace();
            }           
        }
    });
}
}

尝试在下一行中将 localhost 替换为您系统的 IP 地址。

private static final String URL = "http://localhost:49934/Service1.asmx";

这可能会帮助你。

即使您在同一系统上运行的模拟器上对其进行测试，那么在某些情况下，asp.net 和 android 的 localhost 也可能具有不同的 IP 可能为 10.0.2.2。

我之前也遇到过类似的问题。请查看How to call a local .NET web service from an Android Application。

希望能帮助到你
