Android - SimpleXML框架無法解析@ElementList

我正在使用SimpleXML框架來解析我的Android應用程序中的xml。我在正確解析@ElementList時遇到問題。Android - SimpleXML框架無法解析@ElementList

XML的片段：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 
<SaleToPOIResponse> 
    <MessageHeader (...) /> 
    <ReconciliationResponse ReconciliationType="SaleReconciliation"> 
     <Response Result="Success"/> 
     <TransactionTotals PaymentInstrumentType="Card"> 
      <PaymentTotals TransactionType="Debit" TransactionCount="182" TransactionAmount="4.17"/> 
      <PaymentTotals TransactionType="Credit" TransactionCount="1" TransactionAmount="2.01"/> 
     </TransactionTotals> 
    </ReconciliationResponse> 
</SaleToPOIResponse>

我的類看起來：

ReconciliationResponseType.java：

@Root 
    @Order(elements = { 
      "Response", 
      "TransactionTotals" 
    }) 
    public class ReconciliationResponseType { 

     @Element(name = "Response", required = true) 
     protected ResponseType response; 
     @ElementList(name = "TransactionTotals", inline = true, required = false) 
     protected List<TransactionTotalsType> transactionTotals; 
     @Attribute(name = "ReconciliationType", required = true) 
     protected String reconciliationType; 

    // getters and setters 
    }

TransactionTotalsType.java：

@Root 
    @Order(elements = { 
      "PaymentTotals", 
      "LoyaltyTotals" 
    }) 
    public class TransactionTotalsType { 

     @ElementList(name = "PaymentTotals", inline = true, required = false) 
     protected List<PaymentTotalsType> paymentTotals; 
     @Attribute(name = "PaymentInstrumentType", required = true) 
     protected String paymentInstrumentType; 

    // getters and setters 
    }

我用它解析方法：

public static SaleToPOIResponse fromXMLString(String xmlResponse) { 
    Reader reader = new StringReader(xmlResponse); 

    Serializer serializer = new Persister(); 
    try { 
     SaleToPOIResponse response = serializer.read(SaleToPOIResponse.class, reader, false); 
     return response; 
    } catch (Exception e) { 
     Log.e(TAG, "Exception during parsing String XML to SaleToPOIResponse: ", e); 
    } 
    return null; 
}

但每次我得到一個異常時，下令元素「TransactionTotals」缺少，即使1）不要求2）它在解析XML

org.simpleframework.xml.core.ElementException: Ordered element 'TransactionTotals' missing for class pl.novelpay.epas.generated.saletopoimessages.ReconciliationResponseType

存在當我從@Order評論'TransactionTotals'時，xml被解析而沒有異常，但是結果中的TransactionTotals是空的。我在這裏錯過了什麼？

我發現在閱讀的答案在這裏類似的問題是什麼是一個問題： https://sourceforge.net/p/simple/mailman/message/25699359/

我用的entryname insted的。因此ElementList屬性應該看起來像這樣：

@ElementList(entry= "PaymentTotals", inline = true, required = false) 
protected List<PaymentTotalsType> paymentTotals;

現在它完美地工作。
