public static void initXML(Context context) {        //can't create in /data/media/0 because permission         //can create in /sdcard/hotel        File mSettings = new File(HOTEL_PATH_XML);        if (!mSettings.exists()) {            mSettings.mkdirs();        }        File settings = new File(mSettings,"settings.xml");        Log.i("XmlPullParser-----settings", settings+"+1+");        if (!settings.exists()) {            try {                Log.i("XmlPullParser-----settings", settings+"+2+");                settings.createNewFile();                initSettings(settings);            } catch (IOException e) {                e.printStackTrace();                return;            }            return;        }                 try {            XmlPullParserFactory factory = XmlPullParserFactory.newInstance();            factory.setNamespaceAware(true);            XmlPullParser xpp = factory.newPullParser();            xpp.setInput(new FileInputStream(settings), "utf-8");            int eventType = xpp.getEventType();            while (eventType != XmlPullParser.END_DOCUMENT) {                Log.i("XmlPullParser-----TAG", eventType+"");                if (eventType == XmlPullParser.START_TAG) {                    String tag = xpp.getName();                    Log.i("XmlPullParser-----TAG", "tag---------"+tag+"");                    if (tag.equals("item")) {                        String id = xpp.getAttributeValue(null, "id");                        String value = xpp.getAttributeValue(null, "value");                        if (id.equals("server")) {                            sServerAddr = value;                        } else if (id.equals("hotel")) {                            sHid = value;                        } else if (id.equals("room")) {                            sRoomNum = value;                        }                    }                }                eventType =;            }            Log.i("XmlPullParser-----TAG", eventType+"exist the xunhuan");        } catch (XmlPullParserException e) {            e.printStackTrace();        } catch (FileNotFoundException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        }     }

Generate XML file

// No line breaks are generated by default.
Public static void initSettings (final File settings) {new Thread (new Runnable () {@ Override public void run () {FileOutputStream fos = null; try {fos = new FileOutputStream (settings); XmlSerializer serializer = Xml. newSerializer (); serializer. setOutput (fos, "UTF-8"); serializer. startDocument ("UTF-8", true); serializer. startTag (null, "config"); serializer. startTag (null, "category"); serializer. att Ribute (null, "name", "hot"); // server serializer. startTag (null, "item"); serializer. attribute (null, "id", "server"); serializer. attribute (null, "value", ""); serializer. endTag (null, "item"); // hid serializer. startTag (null, "item"); serializer. attribute (null, "id", "hotel"); serializer. attribute (null, "value", ""); serializer. endTag (null, "item"); // room serializer. startTag (null, "item"); serial Izer. attribute (null, "id", "room"); serializer. attribute (null, "value", ""); serializer. endTag (null, "item"); serializer. endTag (null, "category"); serializer. endTag (null, "config"); serializer. endDocument (); serializer. flush ();} catch (FileNotFoundException e) {e. printStackTrace ();} catch (IllegalArgumentException e) {e. printStackTrace ();} catch (IllegalStateException e) {e. printStackTrace () ;} Catch (IOException e) {e. printStackTrace ();} finally {if (fos! = Null) {try {fos. close () ;}catch (IOException e) {e. printStackTrace () ;}}}). start ();}
