連續發送數據

Question

android應用程序是這樣的一種方式，當數據被髮送（單擊按鈕）到USB設備時，LED切換並顯示數據。我希望數據在沒有任何手動干預的情況下連續發送。好心幫

if (mInputStream != null) 
     { 
      int Data = 0; 
      try { 
      Data = mInputStream.read(); 
      } catch (IOException e) { 
      } 
      if (Data == LED_ON) 
      { 

      ledStatus.setText("LED is ON");    
      } 
      else if (Data == LED_OFF) 
      { 

      ledStatus.setText("LED is OFF");         
      } 
     else 
     { 
      ledStatus.setText("Request failed");     
     } 

      } 
      else 
      { 
     ledStatus.setText("mInputStream == null"); 

      }

這時候我已經測試它自己... 它絕對應該工作 其粘貼到您的onCreate（）好運:)

Timer t = new Timer(); 
     t.schedule(new TimerTask(){ 
       public void run(){ 
          // write the method name here. which you want to call continuously 
        Log.d("timer", "timer"); 
        } 
        },10, 1000);
