POJO类转化成XML字符串

1 public static String writeXml(List data){ 2 XmlSerializer serializer = Xml.newSerializer(); 3 StringWriter writer = new StringWriter(); 4 try{ 5 serializer.setOutput(writer); 6 // 7 serializer.startDocument("UTF-8",true); 8 serializer.startTag("","Locations"); 9 10 for(int i=0;i< }42 RuntimeException(e);41 new throw {40 e)39 catch(Exception }38 writer.toString();37 return serializer.endDocument();36 serializer.endTag(??,?Locations?);35 34 33 }32 31 serializer.endTag(??,?Location?);30 29 serializer.endTag(??,?longitude?);28 serializer.text(String.valueOf(data.get(i).getLocation_longitude()));27 serializer.startTag(??,?longitude?);26 25 serializer.endTag(??,?latitude?);24 serializer.text(String.valueOf(data.get(i).getLocation_latitude()));23 serializer.startTag(??,?latitude?);22 21 serializer.endTag(??,?ring?);20 serializer.text(data.get(i).getLocation_ring());19 serializer.startTag(??,?ring?);18 17 serializer.endTag(??,?id?);16 serializer.text(data.get(i).getLocation_Id());15 serializer.startTag(??,?id?);14 13 serializer.startTag(??,?Location?);12>

有了XML的字符串后只要将它存储起来就行，需要使用是再读取

以下是存储和读取文件函数。由于SD卡的读取还需要判断SD卡的状态，函数比较长，就贴存手机内存的代码

反正大同小异

1 public static InputStream readInternalFileInputStream(Context context,String fileName){ 2 /** 3 * 读取手机内存文件 4 * */ 5 6 try{ 7 FileInputStream fis = context.openFileInput(fileName); 8 9 return fis;10 }catch(Exception e){11 return null;12 }13 14 }15 public static String readInternalFile(Context context,String fileName){16 /**17 * 读取手机内存文件18 * */19 20 try{21 byte[] buffer = new byte[512];22 int read =0;23 StringBuffer stringbuffer = new
