四. 使用

下面，我们实现一个通用的功能类KSoap2Utility，下面是这个类的实现代码：

package utility;

import android.content.res.Resources;
import android.os.Handler;
import android.os.Message;
import android.util.Log;

import com.example.ygh.vcsosapplication.R;

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

import java.util.Iterator;
import java.util.LinkedList;
import java.util.List;
import java.util.Map;
