내 코드는 다음과 같습니다

private void sendMsg(boolean delayed) { 
    if(mNotificationSoundHandler == null) { 
     mNotificationSoundHandler = new Handler() { //may be some prob with this 

      public void handleMessage(Message msg) { 
       super.handleMessage(msg); 
       Log.d(TAG, " !!!Handle Message !!!"); 
       updateSoundLocked(); 
      } 

    }; 
} 

Answer 1

당신은 UI 스레드 밖에서 UI를 업데이트 할 수 없습니다. 이 같은 것을 수행해야합니다 심지어

getActivity().runOnUiThread(new Runnable() { 
    updateSoundLocked(); 
}); 

또는를 :

는

private void sendMsg(boolean delayed) { 
    if(mNotificationSoundHandler == null) { 
     mNotificationSoundHandler = new Handler(Looper.getMainLooper()) { 

      public void handleMessage(Message msg) { 
       super.handleMessage(msg); 
       Log.d(TAG, " !!!Handle Message !!!"); 
       updateSoundLocked(); 
      } 
     }; 
    } 
}
