Question

我正在android中创建一个虚拟应用程序。这个应用程序从Web服务调用一个方法。该方法用于添加数字。我提供两个整数输入，它应该返回一个整数值，但它输出0作为输出（无论输入是什么）。请帮帮我。

下面是我的java代码

public class MainActivity extends Activity {

private static String SOAP_ACTION = "http://tempuri.org/Add";
private static String NAMESPACE = "http://tempuri.org/";
private static String METHOD_NAME = "Add";
private static String URL = "http://192.168.0.136/asmxfirst/Calculation.asmx?WSDL";

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final EditText editText1 = (EditText) findViewById(R.id.editText1);
    final EditText editText2 = (EditText) findViewById(R.id.editText2);
    final EditText editText3 = (EditText) findViewById(R.id.editText3);

    Button btn = (Button) findViewById(R.id.button1);
    btn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
            request.addProperty("a", Integer.parseInt((editText1.getText().toString())));
            request.addProperty("b", Integer.parseInt((editText2.getText().toString())));   

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.setOutputSoapObject(request);
            envelope.dotNet = true;
            try {
             HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
             androidHttpTransport.call(SOAP_ACTION, envelope);
             Object result = envelope.getResponse();
             if(result != null)
             {
                  String[] results = (String[]) result;
                   editText3.setText(results[0]);
             }
             else
             {
                   Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show();
             }
            } 
            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.activity_main, menu);
    return true;
}

}

使用soapobject

SoapObject result = (SoapObject)envelope.bodyIn;

            if(result != null)
            {
                  //Get the first property and change the label text
                   editText3.setText(result.getProperty(0).toString());
            }
            else
            {
                  Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show();
            }
