   dir.mkdirs();
}
try {
   File file = new File(localAdd + "/" + imageName);
   OutputStream os = new FileOutputStream(file);
   URL url = new URL(Url);
   InputStream is = url.openStream();
   byte[] buff = new byte[1024];
   while (true) {
       int readed = is.read(buff);
       if (readed == -1) {
           break;
       }
       byte[] temp = new byte[readed];
       System.arraycopy(buff, 0, temp, 0, readed);
       // 写入文件
       os.write(temp);
   }
   is.close();
   os.close();
} catch (Exception e) {
   e.printStackTrace();
}
