Android中使用XmlSerializer拼装XML数据

   经常在Http Post Xml请求的时候，需要如何拼装XML数据，在Android中如何来做的呢，通常我们使用FastXmlserializer这个类。比如要拼装如下的XML

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Request xmlns="http://www.demo.com">
  <operation>GetCustomerTariffInfo</operation>
  <CustomerTariffInfoRequest>
     <msisdn>44079324110</msisdn>
     <detailsInfo>true</detailsInfo>
  </CustomerTariffInfoRequest>
</Request>

 

代码如下

try {
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            XmlSerializer serializer = new FastXmlSerializer();
            serializer.setOutput(out, "utf-8");
           
           //  true可以让stanalone为Yes.
            serializer.startDocument("utf-8", true);
           
            serializer.setFeature("http://xmlpull.org/v1/doc/features.html#indent-output", true);
            serializer.startTag(null, "request");
           //设置属性
            serializer.attribute(null,"xmlns","http://www.demo.com");
            serializer.text("\n");
           
            serializer.startTag(null, "account");
            serializer.text("");
            serializer.endTag(null, "account");
            serializer.startTag(null, "nickname");
            serializer.text("");
            serializer.endTag(null, "nickname");
            serializer.startTag(null, "password");
            serializer.text("");
            serializer.endTag(null, "password");
           
            serializer.endTag(null, "request");
            serializer.endDocument();
           
            out.flush();
            return out.toByteArray();
       
        } catch (Exception e) {
            e.printStackTrace();
        }
