XML文件的解析，代码：
1 public void click(View v) { 2 InputStream is = getClassLoader().getResourceAsStream("weather.xml"); 3 //获取到XMLPullParse接口的对象 4 XmlPullParser xpp = Xml.newPullParser(); 5 try { 6 //设置输出流及编码 7 xpp.setInput(is, "utf-8"); 8 //获取到节点的类型，START_DOCUMENT=0，END_DOCUMENT=1，START_TAG=2，END_TAG=3，TEXT=4 9 int type = xpp.getEventType(); 10 CityBean city = null; 11 //当前节点不是END_DOCUMENT的话，就一直循环遍历XML文件 12 while (type!=XmlPullParser.END_DOCUMENT) { 13 //使用switch判断type类型 14 switch (type) { 15 //type为2的情况下，进入START_TAG 16 case XmlPullParser.START_TAG: 17 //获取当前节点的名字是weather 18 if ("weather".equals(xpp.getName())) { 19 //city的集合 20 cityList=new ArrayList<>(); 21 }else if ("city".equals(xpp.getName())) { 22 city = new CityBean(); 23 }else if ("name".equals(xpp.getName())) { 24 String name = xpp.nextText(); 25 city.setName(name); 26 }else if ("temp".equals(xpp.getName())) { 27 String temp = xpp.nextText(); 28 city.setTemp(temp); 29 }else if ("pm".equals(xpp.getName())) { 30 String pm = xpp.nextText(); 31 city.setPm(pm); 32 } 33 break; 34 case XmlPullParser.END_TAG: 35 if ("city".equals(xpp.getName())) { 36 cityList.add(city); 37 } 38 break; 39 default: 40 break; 41 } 42 //把解析的指针移动到下一个节点 43 type=xpp.next(); 44 } 45 for (CityBean c1 : cityList) { 46 System.out.println(c1.toString()); 47 } 48 } catch (Exception e) { 49 e.printStackTrace(); 50 } 51 }
XML文件的创建，代码：
1 File file = new File(Environment.getExternalStorageDirectory(),"info3.xml"); 2 XmlSerializer xml = Xml.newSerializer(); 3 try { 4 FileOutputStream fos = new FileOutputStream(file); 5 xml.setOutput(fos, "utf-8"); 6 xml.startDocument("utf-8", true); 7 xml.startTag(null, "message"); 8 for (SmsBean smsBean : smsList) { 9 xml.startTag(null, "sms"); 10 xml.startTag(null, "body"); 11 xml.text(smsBean.getBody()); 12 xml.endTag(null, "body"); 13 xml.startTag(null, "address"); 14 xml.text(smsBean.getAddress()); 15 xml.endTag(null, "address"); 16 xml.startTag(null, "date"); 17 xml.text(smsBean.getDate()); 18 xml.endTag(null, "date"); 19 xml.startTag(null, "type"); 20 xml.text(smsBean.getType()); 21 xml.endTag(null, "type"); 22 xml.endTag(null, "sms"); 23 } 24 xml.endTag(null, "message"); 25 xml.endDocument(); 26 fos.close(); 27 } catch (Exception e) { 28 29 e.printStackTrace(); 30 }
