Question

我正在为Microsoft Dynamics NAV开发Android客户端。我正在使用ksoap2与NAV webservices进行通信。我使用MarshalDate类来序列化日期。当我将Date传递给webservice时，我收到类似＆＃34的错误;字符串未被识别为有效的DateTime。＆＃34;

MarshalDate.java

public class MarshalDate implements Marshal { 

public static Class DATE_CLASS = new Date().getClass();
public Object readInstance(XmlPullParser parser, String namespace, String name, PropertyInfo expected) throws IOException, XmlPullParserException { 
    return IsoDate.stringToDate(parser.nextText(), IsoDate.DATE_TIME); 
    } 
public void register(SoapSerializationEnvelope cm) { 
    cm.addMapping(cm.xsd, "dateTime", Date.class, this); }
public void writeInstance(XmlSerializer writer, Object obj) throws IOException {
    writer.text(IsoDate.dateToString((Date) obj, IsoDate.DATE_TIME)); } }

我的salesordercard对象，

SalesOrderCard.java

    public class SalesOrderCard implements KvmSerializable
{
    String Key;
    String No;
    String Sell_to_Customer_No;
    Sales_Order_Line_List Salesorderlinelist;
        String ShopNo;
        Date OrderDate;
    double Received_Amount;
    boolean Cheque;


    public SalesOrderCard(){}


    public SalesOrderCard(String key,String no,String selltocustno,Sales_Order_Line_List salesorderline,String shopno,Date orderdate ,double received_Amount,boolean  cheque) {

        Key = key;

我正在传递约会，

    String DateString="22-05-2014 19:32:52";
    SimpleDateFormat format=new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
    d=(Date)format.parse(DateString);

    SalesOrderCard cr=new SalesOrderCard();
    cr.OrderDate=d;


    PropertyInfo custProp = new PropertyInfo();
   custProp.setName("SalesOrderCard");
   custProp.setValue(cr);
   custProp.setType(SalesOrderCard.class);
   request.addProperty(custProp);
  SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
   MarshalDouble md = new MarshalDouble();
   md.register(envelope);
   MarshalDate mdate=new MarshalDate();
   mdate.register(envelope);

Answer 1

假设d是日期，则此代码看起来正确

String DateString="22-05-2014 19:32:52";
SimpleDateFormat format=new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
d=(Date)format.parse(DateString);

我怀疑这一行可能是问题

writer.text(IsoDate.dateToString((Date) obj, IsoDate.DATE_TIME));

如果您知道writer.text期望的格式，那么我会尝试使用SimpleDateFormat为您创建字符串：

String dateString = format.format((Date)obj);

在Android中，字符串未被识别为有效的DateTime
