麦子学院Android开发教程XmlSerializer生成XML文件.docx

IT在线教育领先平台麦子学院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 File f = new File(getExternalCacheDir().getAbsolutePath()+my.xml);OutputStream outPut = new FileOutputStream(f); XmlSerializer serializer=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, s0); serializer.attribute(null, DBUtil.KEY_CITYNAME, s1); serializer.attribute(null, DBUtil.KEY_NAME, s2); serializer.attribute(null, DBUtil.KEY_TELE, s3); serializer.endTag(null, DBUtil.TAXI_TABLE); serializer.endTag(null, companys); serializer.endDocument(); outPut.close(); catch (IOException e) / TODO Auto-generated catch block e.printStackTrace(); 实例2 代码如下private static void XmlFileCreator(List data) File newxmlfile = new File(Environment.getExternalStorageDirectory()+/new.xml); File newxmlfile = (List data) try if(!newxmlfile.exists() newxmlfile.createNewFile(); catch(IOException e) Log.e(IOException, exception in createNewFile() method); /we have to bind the new file with a FileOutputStream FileOutputStream fileos = null; try fileos = new FileOutputStream(newxmlfile); catch(FileNotFoundException e) Log.e(FileNotFoundException, cant create FileOutputStream); /we create a XmlSerializer in order to write xml data XmlSerializer serializer = Xml.newSerializer(); try /we set the FileOutputStream as output for the serializer, using UTF-8 encoding serializer.setOutput(fileos, UTF-8); /Write ?xml declaration with encoding (if encoding not null) and standalone flag (if standalone not null) serializer.startDocument(null, Boolean.valueOf(true); /set indentation option serializer.setFeature(/v1/doc/features.html#indent-output, true); /start a tag called root serializer.startTag(null, jokes); for(JokeBean joke:data) serializer.startTag(null, joke); /i indent code just to have a view similar to xml-tree serializer.startTag(null, id); serializer.text(joke.getId(); serializer.endTag(null, id); serializer.startTag(null, title); serializer.text(joke.getTitle(); /set an attribute called attribute with a value for /serializer.attribute(null, attribute, value); serializer.endTag(null, title); serializer.startTag(null, text); /write some text inside serializer.text(joke.getText(); serializer.endTag(null, text); serializer.endTag(null, joke); serializer.endTag(null, jokes); serializer.endDocument(); /write xml data into the FileOutputStream serializer
