在安卓手机开发中生成xml文档的文章相对来说比较少，下面我来介绍利用XmlSerializer在安卓中生成xml文档的方法，有需要了解的朋友可参考。
例1
代码如下
try{
Filef=newFile(getExternalCacheDir().getAbsolutePath()+"my.xml");
OutputStreamoutPut=newFileOutputStream(f);
XmlSerializerserializer=Xml.newSerializer();
serializer.setOutput(outPut,"utf-8");

serializer.startDocument("utf-8",true);
serializer.startTag(null,"companys");

for(String[]s:taxiCompany)
{
serializer.startTag(null,DBUtil.TAXI_TABLE);

serializer.attribute(null,DBUtil.KEY_PROVINCE,s[0]);
serializer.attribute(null,DBUtil.KEY_CITYNAME,s[1]);
serializer.attribute(null,DBUtil.KEY_NAME,s[2]);
serializer.attribute(null,DBUtil.KEY_TELE,s[3]);

serializer.endTag(null,DBUtil.TAXI_TABLE);
}

serializer.endTag(null,"companys");
serializer.endDocument();
outPut.close();
}catch(IOExceptione){
//TODOAuto-generatedcatchblock
e.printStackTrace();
}
实例2
代码如下
privatestaticvoidXmlFileCreator(List<JokeBean>data){
Filenewxmlfile=newFile(Environment.getExternalStorageDirectory()+"/new.xml");
Filenewxmlfile=www.maiziedu.com(List<JokeBean>data)
try{
if(!newxmlfile.exists())
newxmlfile.createNewFile();
}catch(IOExceptione){
Log.e("IOException","exceptionincreateNewFile()method");
}
//wehavetobindthenewfilewithaFileOutputStream
FileOutputStreamfileos=null;
try{
fileos=newFileOutputStream(newxmlfile);
}catch(FileNotFoundExceptione){
Log.e("FileNotFoundException","can'tcreateFileOutputStream");
}
//wecreateaXmlSerializerinordertowritexmldata
XmlSerializerserializer=Xml.newSerializer();
try{
//wesettheFileOutputStreamasoutputfortheserializer,usingUTF-8encoding
serializer.setOutput(fileos,"UTF-8");
//Write<?xmldeclarationwithencoding(ifencodingnotnull)andstandaloneflag(ifstandalonenotnull)
serializer.startDocument(null,Boolean.valueOf(true));
//setindentationoption
serializer.setFeature("http://xmlpull.org/v1/doc/features.html#indent-output",true);
//startatagcalled"root"
serializer.startTag(null,"jokes");
for(JokeBeanjoke:data){
serializer.startTag(null,"joke")
