显示计数计时器

Question

我想在我的 android 应用程序中以 yy-MM-dd h:m:s 格式显示倒数计时器

我试过的： 我尝试操纵 CountDownTimer，使其以相反的顺序工作。将间隔更改为 -1000 或每秒向倒计时添加 2000 毫秒。两者都不起作用。然后我想我应该使用 Chronometer class。就我而言，标准 Chronometer 仅显示小时、分钟和秒。所以没有天，没有月，没有年。

还有一件事

如果时间少于 1 分钟，则计时器仅显示秒数，如下所示

00 秒
如果少于 1 小时则只有分钟和秒那么格式应该是

00 分 00 秒
如果少于 1 天则只有小时、分钟和秒

00 小时 00 分 00 秒
如果少于 1 个月则只显示天、小时、分钟、秒

0 天 00 小时 00 分 00 秒
如果少于一年则只显示月、日、小时、分钟、秒

0 个月 0 天 00 小时 00 分 00 秒
如果超过一年就显示像

0 年 0 个月 0 天 00 小时 00 分 00 秒

我写的代码

  chronometer.setFormat("%s");
    chronometer.setBase(SystemClock.elapsedRealtime());
    chronometer.setOnChronometerTickListener(new Chronometer.OnChronometerTickListener() {
        @Override
        public void onChronometerTick(Chronometer chronometer) {

            String cTextSize = chronometer.getText().toString();

           if ((SystemClock.elapsedRealtime() - chronometer.getBase()) < 60000) {
               chronometer.setText(cTextSize.substring(3,5)+" sec");

            }
            else if (((SystemClock.elapsedRealtime() - chronometer.getBase()) >= 60000)  &&  ((SystemClock.elapsedRealtime() - chronometer.getBase()) < 3600000)){
                chronometer.setText(cTextSize.substring(0,2)+" mins "+cTextSize.substring(3,5)+" sec");
            }
            else if (((SystemClock.elapsedRealtime() - chronometer.getBase()) >= 3600000)  &&  ((SystemClock.elapsedRealtime() - chronometer.getBase()) < 86400000)){
                chronometer.setText(cTextSize.substring(0,2)+" hours "+cTextSize.substring(3,5)+" mins "+cTextSize.substring(6,8)+" sec");
            }
}

这里的代码运行正常，直到显示小时数，但现在我想如果小时数大于 24，它显示 1 天而不是第 25 小时

非常感谢您的帮助，如果您不知道答案，请不要投反对票

非常感谢所有 google 认证的开发人员帮助我。无论如何，这就是我解决问题的方法
