public static Bitmap readInputStreamToBitmap(InputStream ins, int fileSize) {      if (ins == null) {          return null;      }     byte[] b;     ByteArrayOutputStream bos = new ByteArrayOutputStream();      try {          byte[] buffer = new byte[1024];          int size = -1;          int len = 0;// 已经接收长度         size = ins.read(buffer);         while (size != -1) {             len = len + size;//             bos.write(buffer, 0, size);              if (fileSize == len) {// 接收完毕                           break;         }        size = ins.read(buffer);         }          b = bos.toByteArray();         bos.close();     } catch (IOException e) {          e.printStackTrace();          return null;      }      if (b.length != 0) {          return BitmapFactory.decodeByteArray(b, 0, b.length);      }      return null;         }
