Android倒计时!

设置时间以换算成int值:

CountDownTimer timer = new CountDownTimer(7199000, 1000) {    @Override    public void onTick(long millisUntilFinished) {        time.setText(formatTime((int) (millisUntilFinished/1000)));    }    @Override    public void onFinish() {    }};timer.start();

设置小时的时,分,秒:

public static String formatTime(int time){    int hh = time/3600;    int mm = (time-3600*hh)/60;    int ss = (time-3600*hh-60*mm);    StringBuilder sb = new StringBuilder();    sb.append(hh+"时");    if(mm<10){        sb.append("0"+mm+"分");    }else{        sb.append(mm+"分");    }    if(ss<10){        sb.append("0"+ss+"秒");    }else{        sb.append(ss+"秒");    }    return sb.toString();}
