为什么不是onChronometerTick被称为？ [英] Why isn't onChronometerTick being called?

问题描述

我的code从未进入onChronometerTick方法。我在做什么错误？我需要以某种方式设置滚动时间？我不能想出一个办法做到这一点。

  elapsedTimer.setOnChronometerTickListener（新Chronometer.OnChronometerTickListener（）{
    @覆盖
    公共无效onChronometerTick（天文台时计）{
        计数进位[0] =（SystemClock.elapsedRealtime（） -  chronometer.getBase（））/ 1000;
        elapsedTimeDynamic.setText（+计数进位）;
    }
}）;
elapsedTimer.start（）;
 

解决方案

对于谁是有使用精密时计为经过的定时器/秒表麻烦，不能算出它未来的任何人，我结束了再杀天文台表，并使用CountDownTimer的，但以这样的方式使用它，它会也向上计数

 最终长STARTTIME = System.currentTimeMillis的（）;
elapsedTimer =新CountDownTimer（activityTime + 1000，100）{
    @覆盖
    公共无效onTick（长升）{        长ela​​psedTime = System.currentTimeMillis的（） -  startTime时;
        elapsedTime = elapsedTime / 1000;
        elapsedTimeTextView.setText（的String.format（％02D，（elapsedTime）））;
    }    @覆盖
    公共无效onFinish（）{    }
}。开始（）;
 

My code never enters the onChronometerTick method. What am I doing incorrectly? Do I need to set the tick time somehow? I can't figure out a way to do that.

elapsedTimer.setOnChronometerTickListener(new Chronometer.OnChronometerTickListener() {
    @Override
    public void onChronometerTick(Chronometer chronometer) {
        countUp[0] = (SystemClock.elapsedRealtime() - chronometer.getBase()) / 1000;
        elapsedTimeDynamic.setText("" + countUp);
    }
});
elapsedTimer.start();

解决方案

For anyone in the future who is having trouble using chronometer for an elapsed timer/stopwatch and can't figure it out, I ended up scrapping chronometer and using CountDownTimer, but using it in such a way that it would also count up:

final long startTime = System.currentTimeMillis();
elapsedTimer = new CountDownTimer(activityTime + 1000, 100) {
    @Override
    public void onTick(long l) {

        long elapsedTime = System.currentTimeMillis() - startTime;
        elapsedTime = elapsedTime/1000;
        elapsedTimeTextView.setText(String.format("%02d", (elapsedTime)));
    }

    @Override
    public void onFinish() {

    }
}.start();
