串口通信 我可以接受到数据了  但是怎么显示出来 求各位帮个忙  代码如下

复制代码 handler1 = new Handler() {             public void handleMessage(Message msg) {                 switch (msg.arg1) {                 case 0:                      // int len = HardwareControler.read(fd, buf, 8);                                                                           readThread   readth =new readThread();                         readth.start();//处理完消息后立即开启监听线程                     try {                         readth.sleep(200);                                              } catch (InterruptedException e) {                         // TODO Auto-generated catch block                         e.printStackTrace();                     }                     fd = HardwareControler.openSerialPort(choosed_serial, 115200, 8, 1);                     byte[] readBuffer = new byte[20];                                        String str=new String(readBuffer);                   commucationText.append(str+"\n");                         Log.d(thread,"接收到数据，新线程启动");                         break;                     case 1:                                              HardwareControler.setLedState(1, 0);                         new readThread().start();                     Log.d(thread,"没有数据，新线程启动");                         break;                     default:                         break;                     }                 }             };
