Android :: Make Toast Last For Longer Time?

Is there a way to make the Toast last for longer time? I have tried this code

Toast t = new Toast(this); View v = View.inflate(this, R.toast_layout, null); t.setView(v); t.setDuration(Toast.LENGTH_LONG); t.show(); t.show(); t.show();

By calling show() method more than once, I hoped this would give a similar effect to lasting for longer time with some flickering, but I didn't see any difference. Is there some limit to the number of times that show() method can be called on the same Toast? e.g. just once per toast instance and further calling has no effect?
