Convert the contents of the XML file to the object list:

PrivateList<person>xmltoobjlist () {xmlpullparser parser=Xml.newpullparser (); InputStream is=NULL; List<Person> Xmldatas =NewArraylist<person>(); Try{ is= Getassets (). Open ("Person.xml"); //associating the XML document to be parsedParser.setinput (IS, "Utf-8"); Person Person=NULL; intevent =Parser.geteventtype (); //does not equal the document End event loop             while(Event! =xmlpullparser.end_document) {                if(Xmlpullparser.start_tag = =event) {                    //The person tag starts                    if("Person". Equals (Parser.getname ())) { person=NewPerson (); intPID = Integer.parseint (Parser.getattributevalue (0));                    Person.setid (PID); }                    //Name label Start                    if("Name". Equals (Parser.getname ())) {String name=Parser.nexttext ();                    Person.setname (name); }                    if("Password". Equals (Parser.getname ())) {String password=Parser.nexttext ();                    Person.setpassword (password); }                }                if(Xmlpullparser.end_tag = =event) {                    //end of person tag                    if("Person". Equals (Parser.getname ()))                    {Xmldatas.add (person); }} Event=Parser.next (); }            //Verification:             for(person P:xmldatas) {log.i ("XML", p.getname () +P.getpassword ()); }        } Catch(IOException e) {e.printstacktrace (); } Catch(xmlpullparserexception e) {e.printstacktrace (); } finally {            if(Is! =NULL) {                Try{is.close (); } Catch(IOException e) {e.printstacktrace (); }            }        }        returnXmldatas; }

Writes the object list content to xml:

Private voidObjtoxml (list<person>Xmldatas) {XmlSerializer Serializer=Xml.newserializer (); OutputStream OS=NULL; Try {            //Save LocationOS = Openfileoutput ("Person.xml", mode_private); Serializer.setoutput (OS,"Utf-8"); //generating an XML fileSerializer.startdocument ("Utf-8",false); //start tag:<persons>Serializer.starttag (NULL, "persons");  for(person Person:xmldatas) {//<person>Serializer.starttag (NULL, "Person"); //Generate ID PropertySerializer.attribute (NULL, "id", String.valueof (Person.getid ())); //<name> TagsSerializer.starttag (NULL, "name"); //contentSerializer.text (Person.getname ()); //</name> TagsSerializer.endtag (NULL, "name"); Serializer.starttag (NULL, "Password");                Serializer.text (Person.getpassword ()); Serializer.endtag (NULL, "Password"); Serializer.endtag (NULL, "Person"); } Serializer.endtag (NULL, "persons"); //Endserializer.enddocument (); } Catch(FileNotFoundException e) {e.printstacktrace (); } Catch(IllegalArgumentException e) {e.printstacktrace (); } Catch(IllegalStateException e) {e.printstacktrace (); } Catch(IOException e) {e.printstacktrace (); } finally {            if(OS! =NULL) {                Try{os.close (); } Catch(IOException e) {e.printstacktrace (); }}} toast.maketext ( This, "Success", Toast.length_short).
