XML檔案的解析，代碼：

 1 public void click(View v) { 2   InputStream is = getClassLoader().getResourceAsStream("weather.xml"); 3   //擷取到XMLPullParse介面的對象 4   XmlPullParser xpp = Xml.newPullParser(); 5   try { 6    //設定輸出資料流及編碼 7    xpp.setInput(is, "utf-8"); 8    //擷取到節點的類型，START_DOCUMENT=0，END_DOCUMENT=1，START_TAG=2，END_TAG=3，TEXT=4 9    int type = xpp.getEventType();10    CityBean city = null;11    //當前節點不是END_DOCUMENT的話，就一直迴圈遍曆XML檔案12    while (type!=XmlPullParser.END_DOCUMENT) {13     //使用switch判斷type類型14     switch (type) {15     //type為2的情況下，進入START_TAG16     case XmlPullParser.START_TAG:17      //擷取當前節點的名字是weather18      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     //把解析的指標移動到下一個節點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檔案的建立，代碼：

 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 }
