嘗試

 scheduler.scheduleAtFixedRate(new Runnable() { 

     public void run() { 
      Log.i("hello", "world"); 
      runOnUiThread(new Runnable() { 
       public void run() { 
        Toast.makeText(getApplicationContext(), "It works", Toast.LENGTH_SHORT).show(); 
       } 
      }); 

     } 
    }, 10, 10, TimeUnit.SECONDS);
