XMLSerializer

startDocument ("utf-8",true); 编码类型，是否独立

endDocument

XmlSerializer serializer= Xml.newSerializer();

serializer.setOutput(openFileOutput("smslist.xml",MODE_PRIVATE),"utf-8");//会在对应包下files/smslist.xml中输出。

serializer.startDocument("utf-8",true); //文档开始声明

serializer.startTag(null,"SMSList");//命名空间 ， 标签名

for(SMS sms:smsList){

serializer.startTag(null,"SMS");

serializer.startTag(null,"from");

serializer.text(sms.from); //设置内容

serializer.endTag(null,"from");

serializer.startTag(null,"content");

serializer.text(sms.content);

serializer.endTag(null,"content");

serializer.startTag(null,"time");

serializer.text(sms.time);

serialize

r.endTag(null,"time");

serializer.endTag(null,"SMS");

}

serializer.endTag(null,"SMSList");//结束标签

serializer.endDocument();

序列化对象思路：Xml.newSerializer();->serializer.setOutput(openFileOutput("name.xml","utf-8");->serializer.startDocument("utf-8",true);->startTag(namespace,"tagname") ->serializer.text("content") ->endTag(namespace,"tagname");->endDocument();

反序列化的思路：用pull解析xml。
