Android Thread, Timer, CountDownTimer

1. Thread

Thread 시작

float threadValue = 100;
new Thread(new Runnable() {
    @Override
    public void run() {
        while(threadValue >= 0) {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    tv_thread.setText(String.format("%.2f", threadValue));
                }
            });
            try {
                Thread.sleep(10);
                threadValue -= 0.01;
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}).start();

Thread 종료

threadValue = 0;
tv_thread.setText(threadValue + "");

2. Timer

Timer 시작

float timerValue = 100;
TimerTask timerTask = new TimerTask() {
    @Override
    public void run() {
        tv_timer.setText(String.format("%.2f", timerValue));
        timerValue -= 0.01;
    }
};
new Timer().schedule(timerTask, 0, 10);

Timer 종료

timerTask.cancel();

3. CountDownTimer

CountDownTimer 시작

float countdowntimerValue = 100;
CountDownTimer countDownTimer = new CountDownTimer(100000, 10) {
    @Override public void onTick(long millisUntilFinished) {
        tv_countdowntimer.setText(String.format("%.2f", millisUntilFinished/1000.));
    }
    @Override public void onFinish() {
        tv_countdowntimer.setText("완료");
    }
};
countDownTimer.start();

CountDownTimer 종료

if(countDownTimer != null) countDownTimer.cancel();
