- xml序列化
- 實現思路 通過程序生成一個xml文件來備份手機短信. 先獲取手機短信的內容 —>通過xml備份.
- StringBuffer 代碼如下
public void click(View view) {StringBuffer sb = new StringBuffer();sb.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");sb.append("<SMSS>");for (SMSbean list : mLists) {sb.append("<SMS>");sb.append("<address>");sb.append(list.getAddress());sb.append("</address>");sb.append("<body>");sb.append(list.getBody());sb.append("</body>");sb.append("<date>");sb.append(list.getDate());sb.append("</date>");sb.append("</SMS>");}sb.append("<SMSS>");try {String s = sb.toString(); // Log.d(TAG, "click: "+s);String path = Environment.getExternalStorageDirectory().getAbsolutePath();Log.d(TAG, "click: " + path);File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), "Config.xml");FileOutputStream fos = new FileOutputStream(file);fos.write(s.getBytes());fos.close();Toast.makeText(this, "保存成功", Toast.LENGTH_SHORT).show();} catch (IOException e) {e.printStackTrace();Toast.makeText(this, "保存失敗", Toast.LENGTH_SHORT).show();}}

- 通過官方提供序列化類實現xml序列化(通過程序生成一個xml)
public void click1(View view) {try {XmlSerializer serializer = Xml.newSerializer();File file = new File(getFilesDir().getPath(), "ConfigCopy.xml");String path = getFilesDir().getPath();Log.d(TAG, "click1: " + path);FileOutputStream fos = new FileOutputStream(file);serializer.setOutput(fos, "utf-8");serializer.startDocument("utf-8", true);serializer.startTag(null, "smss");for (int i = 0; i < mLists.size(); i++) {serializer.startTag(null, "sms");serializer.startTag(null, "address");serializer.text(mLists.get(i).getAddress());serializer.endTag(null, "address");serializer.startTag(null, "body");serializer.text(mLists.get(i).getBody());serializer.endTag(null, "body");serializer.startTag(null, "date");serializer.text(mLists.get(i).getDate());serializer.endTag(null, "date");serializer.endTag(null, "sms");}serializer.endTag(null, "smss");serializer.endDocument();fos.close();Toast.makeText(this, "保存成功", Toast.LENGTH_SHORT).show();} catch (IOException e) {e.printStackTrace();Toast.makeText(this, "保存失敗", Toast.LENGTH_SHORT).show();}}
