【问题描述】：

我正在做一个 android 应用程序，它可以从蓝牙接收数据并将其显示为波形。现在的问题是我想在文本视图中显示数据以确认数据是否正确，但我显示的内容无法识别（如@&zA ...）。任何人都可以帮助将数据转换为 8 位值？谢谢你！

相关编码如下：

  Handler handler = new Handler() {
            @Override 
            public void handleMessage(Message msg) {
                if (msg.what==READ) { 
                    String str = (String)msg.obj;
                    textView1.setText(str); 
                }
                super.handleMessage(msg); 
                }
        };

    private class ConnectedThread extends Thread {
        private final InputStream mmInStream;
        public ConnectedThread(BluetoothSocket socket) {
            InputStream tmpIn = null;
            try {
                tmpIn = socket.getInputStream(); 
            }catch (IOException e) { }
            mmInStream = tmpIn; 
        }

        public void run() {  
            byte[] buffer = new byte[5];
            int bytes; // bytes returned from read() 

            // Keep listening to the InputStream until an exception occurs 
            while (true) {
                try {
                    // Read from the InputStream 
                    bytes = mmInStream.read(buffer);
                    // Send the obtained bytes to the UI activity 
                    String str = new String(buffer); 
                    temp = byteToInt(buffer); //Convert byte to int
                    handler.obtainMessage(READ, bytes, -1, str).sendToTarget();

                }catch (Exception e) {
                    System.out.print("read error"); 
                    break;
                }

            }
        }
    }
