안드로이드에서 kSOAP을 사용하여 double 값을 직렬화하는 방법

Question

다음은 코드입니다.

package com.SRS6; 

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

    private static final String METHOD_NAME = "insertquizdata";

       request.addProperty("inttestid",n2); 

       request.addProperty("dblper",n3); 


       SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

kSOAP을 사용하여 double 값을 직렬화하는 방법을 알려주십시오.

Answer 1

Double 및 Date의 데이터 형식을 수동으로 마샬링해야합니다. 샤프 기어 (Sharp Gears)를 보시려면 여기를 클릭하십시오. Double을 마샬링하는 링크는 Implementing KSOAP Marshal Interface입니다.

Answer 2

Android Studio에서 kSOAP2 및 API 19로 MarshalDouble을 사용하려고하면 MarshalFloat 만 사용 가능한 클래스로 인식됩니다. 이 코드를 실행하면 프로젝트에이 코드를 "MarshalDouble.java"라는 자체 자바 클래스에 추가하면됩니다.

import java.io.IOException; 
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()); 
    } 

} 

당신은 다음과 같은 봉투를 등록 할 수 있습니다 :

MarshalDouble md = new MarshalDouble(); 
md.register(envelope);
