输入到字符串

Question

如何从输入流中获取字符串以使其成为通过蓝牙传输的文件的名称？

发送文件时，我将文件名添加到outputStream，然后添加＆＃34; |＆＃34;作为分隔符，然后我将文件字节数组：

 try {
            FileInputStream fis = new FileInputStream(myFile);
            BufferedInputStream bis = new BufferedInputStream(fis, 8 * 1024);
            bis.read(mybytearray, 0, mybytearray.length);

            outStream.write(fileNameOut.getBytes());
            outStream.write("|".getBytes());
            outStream.write(mybytearray, 0, mybytearray.length);

            outStream.flush();
            outStream.close();
        } catch (IOException e) {
            Log.e("BT Connected", "disconnected", e);
        }

收到文件时，我希望得到所有字节，直到＆＃34; |＆＃34;字符并将它们保存为字符串，以便成为将写入蓝牙传输字节的新文件的文件名：

   try {
     try {
      int read;

// obtain a filename from inputStream
      BufferedInputStream bis = new BufferedInputStream(inStream);
      ByteArrayOutputStream buf = new ByteArrayOutputStream();
      int result = bis.read();
      while (result != -1) {
       buf.write((byte) result);
       result = bis.read();
      }
      //
      general.log("Bluetooth Connected", "file name: " + buf.toString());

      while ((read = inStream.read(buffer)) != -1) {
       transferStatus = "sending";
       bytesRead += read;

       general.log("Bluetooth Connected", "odebrano: " + bytesRead + "bytes: ");

       fos.write(buffer, 0, read);
       transferStatus = "sent";
      }

     } finally {
      outStream.flush();
      inStream.close();
      mmSocket.close();
     }
    } catch (Exception e) {
     general.log("Bluetooth Connected", "======= Error receiving file: " + e);
    }

提交的代码不会查找＆＃34; |＆＃34;字符，因为它甚至没有将字节转换为字符串，我不知道为什么。如何将缓冲流分为两部分：获取字符串直到＆＃34; |＆＃34;并保存为文件名，得到其余的并写入文件？
