我是android新手。我正在创建一个使用Web服务的计算器应用程序。 Web服务是SOAP。所以我包含一个带依赖关系的Ksoap2.jar文件。 我从编辑文本中获取输入，如双数据类型并将其传递给Web服务。 此Web服务调用还将参数作为double和调用函数添加从服务器添加和返回结果。

我的Android等号按钮调用web服务的代码是：

private void onEqualsButtonClick() {        
    secondNumber = Double.parseDouble(editTextInput.getText().toString());
    //secondNumber = Integer.parseInt(editTextInput.getText().toString());
    editTextInput.setText("");
    if(flag==1){            
        //Initialize soap request + add parameters
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);       

        //Use this to add parameters
        request.addProperty("number1",firstNumber);
        request.addProperty("number2",secondNumber);

        //Declare the version of the SOAP request
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        envelope.setOutputSoapObject(request);
        try {
              HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
              androidHttpTransport.debug = true;
              //this is the actual part that will call the  
              androidHttpTransport.call(SOAP_ACTION, envelope);
              // Get the SoapResult from the envelope body.
              SoapObject result = (SoapObject)envelope.bodyIn;
              if(result != null){
                    //Get the first property and change the label text
                    editTextInput.setText(""+result.getProperty(0).toString());
              } else{
                    Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show();
              }
        } catch (Exception e) {
              e.printStackTrace();
        }

Web服务的wsdl是：

我应该在代码中做些什么更改。 请尽快建议我......

还有其他API方法吗？

答案 0 :(得分：3)

是的，我解决了这个问题。 我使用Marshal Class来解决这个问题。 编组类的代码如下：

import org.ksoap2.serialization.Marshal;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
import org.xmlpull.v1.XmlSerializer;

public class MarshalDouble implements Marshal {
    public Object readInstance(XmlPullParser parser, String namespace, String name,
                           PropertyInfo expected) throws IOException, XmlPullParserException {
        return Double.parseDouble(parser.nextText());
    }


    public void register(SoapSerializationEnvelope cm) {
        cm.addMapping(cm.xsd, "double", Double.class, this);
    }


    public void writeInstance(XmlSerializer writer, Object obj) throws IOException {
        writer.text(obj.toString());
    }
}

这个课程的实施如下：

//Marshal class.
MarshalDouble marshaldDouble = new MarshalDouble();
marshaldDouble.register(envelope);

希望这会对所有人有所帮助。
