显示倒数计时器

Umar Ghaffar |

我想以yy-MM-dd h:m:s格式显示我的android应用中的递增计时器

我尝试了什么：我尝试操纵CountDownTimer，以便它以相反的顺序工作。将时间间隔更改为-1000或每秒增加2000毫秒到倒计时。两者都不起作用。然后我想应该使用Chronometer类。就我而言，标准的计时器只显示小时，分钟和秒。因此，没有几天，没有几个月，也没有几年。还有一件事

如果时间少于1分钟，则计时器仅显示秒

00秒
如果少于1小时，则只有几分钟和几秒钟，那么格式应为

00分00秒
如果少于1天，则只有几小时，几分钟和几秒钟

00小时00分钟00秒
如果少于1个月，则仅显示天，小时，分钟，秒

0天00小时00分00秒
如果少于一年，则仅显示月份，天，小时，分钟，秒

0个月0天00小时00分钟00秒
如果超过一年，则显示为

0年0个月0天00小时00分钟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");
            }
}

在这里代码运行良好，直到显示小时，但现在我想如果小时数大于24，则显示1天而不是25小时

非常感谢您的帮助，如果您不知道答案，请不要对它投反对票

好，感谢所有经过Google认证的开发人员为我提供的帮助。无论如何，这就是我解决问题的方式

chronometer.setOnChronometerTickListener(new Chronometer.OnChronometerTickListener() {
        @Override
        public void onChronometerTick(Chronometer chronometer) {

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

            }
