使用ksoap2传递字符串数组到webservice

在android程序中有一个Web Client使用ksoap2，但是还是不能把字符串数组作为一个参数传递到webservice中。
贴出相关代码：

String[] items={"hello","world"};
request.addproperty("str",items);

请求大家的帮忙，谢谢！

好像只能一条条加

public class ExtendedSoapObject extends SoapObject
{
    public ExtendedSoapObject(String namespace, String name)
    {
        super(namespace, name);
    }

    public ExtendedSoapObject(SoapObject o)
    {
        super(o.getNamespace(), o.getName());
        for (int i = 0; i < o.getAttributeCount(); i++)
        {
            AttributeInfo ai = new AttributeInfo();
            o.getAttributeInfo(i, ai);
            ai.setValue(o.getAttribute(i));
            addAttribute(ai);
        }

        for (int i = 0; i < o.getPropertyCount(); i++)
        {
            PropertyInfo pi = new PropertyInfo();
            o.getPropertyInfo(i, pi);
            pi.setValue(o.getProperty(i));
            addProperty(pi);
        }
    }


    @Override
    public SoapObject addProperty(String name, Object value)
    {
        if (value instanceof Object[])
        {
            Object[] subValues = (Object[]) value;
            for (int i = 0; i < subValues.length; i++)
            {
                super.addProperty(name, subValues[i]);
            }
        }
        else
        {
            super.addProperty(name, value);
        }

        return this;
    }


    @Override

        for (int i = 0; i < properties.size(); i++)
        {

            if (prop.getName() != null && prop.getName().equals(name))
            {
                result.add(unwrap(prop));
            }
        }

        if (result.size() == 1)
        {

        }
        else if (result.size() > 1)
        {
            return result.toArray(new Object[0]);
        }
        else
        {
            return null;
        }
    }

    public Object[] getArrayProperty(String name)
    {
        Object o = getProperty(name);
        Object values[] = null;
        if (o != null)
        {
            if (o instanceof Object[])
            {
                values = (Object[]) o;
            }
            else
            {
                values = new Object[1];
                values[0] = o;
            }
        }

        return values;
    }

    Object unwrap(Object o)
    {
        if (o instanceof PropertyInfo)
        {
            return unwrap(((PropertyInfo) o).getValue());
        }
        else if (o instanceof SoapPrimitive || o instanceof SoapObject)
        {
            return o;
        }

        return null;
    }
}

不知此类对你是否有参考价值

首先使用"soapUI"来看正确的请求结构（如名字 item names,命名空间item namespaces）。假定你想在请求里这样写XML（n0和n1是命名空间）：

<n0:strarray xmlns:n0="http://n0 ..." xmlns:n1="http://n1 ...">
        <n1:string>hello</n1:string>
        <n1:string>world</n1:string>
</n0:strarray>

从vector继承一个类：

import java.util.Hashtable;
import java.util.Vector;

import org.ksoap2.serialization.KvmSerializable;
import org.ksoap2.serialization.PropertyInfo;

public class StringArraySerializer extends Vector<String> implements KvmSerializable {
      //n1 stores item namespaces:
    String n1 = "http://n1 ...";

        @Override
        public Object getProperty(int arg0) {
                return this.get(arg0);
        }

        @Override
        public int getPropertyCount() {
                return this.size();
        }

        @Override
        public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
                arg2.setName = "string";
                arg2.type = PropertyInfo.STRING_CLASS;
            arg2.setNamespace = n1;
        }

        @Override
        public void setProperty(int arg0, Object arg1) {
                this.add(arg1.toString());
        }

}

创建请求：
1.创建一个新的Vector-Object

StringArraySerializer stringArray = new StringArraySerializer();

2.然后再添加元素：

stringArray.add("hello");
stringArray.add("world");

3.创建一个 PropertyInfo

//n0存储array namespace:
String n0 = "http://n0 ...";
stringArrayProperty = new PropertyInfo();
stringArrayProperty.setName("strarray");
stringArrayProperty.setValue(stringArray);
stringArrayProperty.setType(stringArray.getClass());
stringArrayProperty.setNamespace(n0);

4.给请求添加所有的属性

Request = new SoapObject(NAMESPACE, METHOD_NAME);
Request.addProperty(stringArrayProperty);

不用楼上那么复杂吧？直接建一个实体对象，然后json序列化成字符串传到webservice，然后那边反序列化成对象。这样不方便很多吗？
