这可以通过Handler.postDelayed(Runnable)或CountdownTimer来实现.

Which one is better in terms of performance?

请参阅下面的示例代码

处理器

new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                 //DO SOMETHING
            }
        },1000);

倒计时器

new CountDownTimer(1000,1000) {
            public void onFinish() {
                 //DO SOMETHING
            }
            public void onTick(long millisUntilFinished) {}
        }.start();
