android.widget.Toast.LENGTH_SHORT | LENGTH_LONG は何秒か？

実際、android.widget.Toast.LENGTH_SHORTとandroid.widget.Toast.LENGTH_LONGは何秒なのか？

• com.android.server.NotificationManager#scheduleTimeoutLocked()
  

  private void scheduleTimeoutLocked(ToastRecord r, boolean immediate)
  {
      Message m = Message.obtain(mHandler, MESSAGE_TIMEOUT, r);
      long delay = immediate ? 0 : (r.duration == Toast.LENGTH_LONG ? LONG_DELAY : SHORT_DELAY);
      mHandler.removeCallbacksAndMessages(r);
      mHandler.sendMessageDelayed(m, delay);
  }

• com.android.server.NotificationManager.LONG_DELAY, SHORT_DELAY
  

  private static final int LONG_DELAY = 3500; // 3.5 seconds
  private static final int SHORT_DELAY = 2000; // 2 seconds

• 2秒と3.5秒なのかな？
