Android 生成 xml文件

利用 XmlSerializer写xml文件。
TestObject对象
private String AdID;
private String Name;
private String URL;

 public boolean createADXML(List<TestObject> data, String localDir) {boolean bFlag = false;SimpleDateFormat sDateFormat = new SimpleDateFormat("yyyyMMddhhmmss");String strTmpName = sDateFormat.format(new java.util.Date()) + ".xml";FileOutputStream fileos = null;File newXmlFile = new File(localDir + strTmpName);try {if (newXmlFile.exists()) {bFlag = newXmlFile.delete();} else {bFlag = true;}if (bFlag) {if (newXmlFile.createNewFile()) {fileos = new FileOutputStream(newXmlFile);// we create a XmlSerializer in order to write xml dataXmlSerializer serializer = Xml.newSerializer();// we set the FileOutputStream as output for the serializer,// using UTF-8 encodingserializer.setOutput(fileos, "UTF-8");// <?xml version=”1.0″ encoding=”UTF-8″>// Write <?xml declaration with encoding (if encoding not// null) and standalone flag (if stan dalone not null)// This method can only be called just after setOutput.serializer.startDocument("UTF-8", null);// start a tag called "root"serializer.startTag(null, "root");serializer.startTag(null, "Test");for (TestObject ad : data) {serializer.startTag(null, "TestObject");serializer.attribute(null, "ADID", ad.getId());serializer.attribute(null, "Name", ad.getName());serializer.attribute(null, "URL", ad.getUrl());serializer.endTag(null, "TestObject");}serializer.endTag(null, "Test");serializer.endTag(null, "root");serializer.endDocument();// write xml data into the FileOutputStreamserializer.flush();// finally we close the file streamfileos.close();}}} catch (Exception e) {}return bFlag;}

生成的XML文件：
<?xml version='1.0' encoding='UTF-8' ?>
<root>
<Test>
<TestObject ADID="9000001" Name="5325ad4" URL="http://www.xxx.com"  />
<TestObject ADID="9000002" Name="5325ad1" URL="http://www.xxx.com" />
<TestObject ADID="9000003" Name="5325ad3" URL="http://www.xxx.com" />
<TestObject ADID="9000004" Name="5325ad2" URL="http://www.xxx.com"  />
</Test>
</root>
