Android uses an XML serializer to generate an XML file

In the article "Android Generate XML File" to write XML format file in the form of a stream, but there is a certain problem, that is, in the text message content can not appear in <> and other parentheses, this article uses the XML serializer to solve

XML Serializer Object

XmlSerializer xs = Xml.newserializer ();
* Set the output stream to the serializer

File File = new file (Environment.getexternalstoragedirectory (), "Backupsms.xml");
FileOutputStream fos = new FileOutputStream (file);
Specifying a good output stream for the serializer
Xs.setoutput (FOS, "utf-8");
* Start generating XML files

Xs.startdocument ("Utf-8", true);
Xs.starttag (NULL, "SMSS");
......

The code is as follows:

 PackageCom.wuyudong.createxml;ImportJava.io.File;ImportJava.io.FileOutputStream;Importjava.util.ArrayList;Importjava.util.List;ImportOrg.xmlpull.v1.XmlSerializer;ImportCom.wuyudong.createxml.domain.Sms;ImportCOM.WUYUDONG.CREATEXML2.R;ImportAndroid.os.Bundle;Importandroid.os.Environment;Importandroid.app.Activity;Importandroid.util.Xml;ImportAndroid.view.View; Public classMainactivityextendsActivity {List<Sms>message; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super.
