public static String writeXML(List<Person> persons, Writer writer){
XmlSerializer serializer = Xml.newSerializer();
try {
serializer.setOutput(writer);
serializer.startDocument("UTF-8", true);
//第一个参数为命名空间,如果不使用命名空间,可以设置为null
serializer.startTag("", "persons");
for (Person person : persons){
serializer.startTag("", "person");
serializer.attribute("", "id", person.getId().toString());
serializer.startTag("", "name");
serializer.text(person.getName());
serializer.endTag("", "name");
serializer.startTag("", "age");
serializer.text(person.getAge().toString());
serializer.endTag("", "age");
serializer.endTag("", "person");
}
serializer.endTag("", "persons");
serializer.endDocument();
return writer.toString();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
File xmlFile = new File("myitcast.xml");
FileOutputStream outStream = new FileOutputStream(xmlFile);
OutputStreamWriter outStreamWriter = new OutputStreamWriter(outStream, "UTF-8");
BufferedWriter writer = new BufferedWriter(outStreamWriter);
writeXML(persons, writer);
writer.flush();
writer.close();
StringWriter writer = new StringWriter(); writeXML(persons, writer); String content = writer.toString();
2、
public static void save(List<Person> persons,OutputStream out)throws Exception{
XmlSerializer xmlSerializer=Xml.newSerializer();
xmlSerializer.setOutput(out, "UTF-8");
xmlSerializer.startDocument("UTF-8", true);
xmlSerializer.startTag(null, "persons");
for(Person person:persons){
xmlSerializer.startTag(null, "person");
xmlSerializer.attribute(null, "id", person.getId().toString());
xmlSerializer.startTag(null, "name");
xmlSerializer.text(person.getName());
xmlSerializer.endTag(null, "name");
xmlSerializer.startTag(null, "age");
xmlSerializer.text(person.getAge().toString());
xmlSerializer.endTag(null, "age");
xmlSerializer.endTag(null, "person");
}
xmlSerializer.endTag(null, "persons");
xmlSerializer.endDocument();
out.flush();
out.close();
}
调用上面方法输出xml文件
public void testSavePerson()throws Exception{
List<Person> persons=new ArrayList<Person>();
persons.add(new Person("zhangss",12,23));
persons.add(new Person("xiaoxiao",45,21));
persons.add(new Person("zhagnni",10,47));
File file=new File(getContext().getFilesDir().toString(),"person.xml");
FileOutputStream out=new FileOutputStream(file);
new PersonService().save(persons, out);
}
使用Pull解析器生成XML文件,布布扣,bubuko.com
