좋아, 해결책을 찾았습니다. 문제는 UI 쓰레드가 UI 쓰레드가 아니기 때문에 UI 쓰레드가 아니라 Handler를 사용하여 Handler에서 UI를 변경하는 코드를 넣고 run() 메소드에서 Handler를 호출하는 것입니다.

uiCallback.sendEmptyMessage(0);

핸들러는 uiCallback라고하고 나는이 길에 핸들러를 정의한다 : 

private Handler uiCallback = new Handler() { 
    public void handleMessage (Message msg) { 
     if (DEBUG) Log.i(TAG, "run() -> Handler"); 
     int[] factor = {0, 2, 4, 6}; 

     data = USBMulti.getLogicAnalizerData(); 
     for(int n = 0; n < 4; ++n) { 
      if(bitTest(data,n)) factor[n] += 1; 
     } 

     input1.add(time,factor[0]); 
     input2.add(time,factor[1]); 
     input3.add(time,factor[2]); 
     input4.add(time,factor[3]); 

     if (DEBUG) Log.i(TAG, "run() -> LogicAnalizerView - mView.repaint()"); 
     if (mView != null) { 
      mView.repaint(); // Redibujo el grafico 
     } 
     time += 0.1; 
    } 
};

그래서 내가 UI 스레드에서 차트를 다시 칠하고 완벽하게 :) 작동합니다.

감사합니다 당신에게 :)

티.

다시 페인트하는 방법을 100 % 확신 할 수는 없지만, 다른 스레드에서 실행되는 경우 동기화 할 수있는 방법이 필요하므로 수정할 때 데이터 세트를 읽지 않아도됩니다.

정확한 방법을 모르겠지만 올바른 방향으로이 점을 알려 주시기 바랍니다.
