我的应用程序是一个带报警类型app的计时器.当计时器到期时,我想将应用程序的主要活动恢复到视图中,如果用户已导航,但应用程序仍在运行.

我展示了我想要放置必要代码的位置:

   public class MyCount extends CountDownTimer {
        public MyCount(long millisInFuture, long countDownInterval) {
          super(millisInFuture, countDownInterval);
        }

        public void onFinish() {

         /** code here to bring the app back to the front / top of stack, in its current state */

         seeker.setProgress(0);
         reset.setBackgroundResource(R.drawable.resetbtnoff);
         playExpiredAlarm(); 
         alarmAnimation.start();
         flasher.setVisibility(View.VISIBLE);
         StopAlarmButtonAnimation.start();
         StopAlarmButton.setVisibility(View.VISIBLE);
         expired = true;
        }

        public void onTick(long millisUntilFinished) {
            remindertimepref = prefs.getString("reminderTime", "<unset>");
            remindtime = Integer.parseInt(remindertimepref.trim());
            timeDisplay.setText(formatTime(millisUntilFinished));
            seeker.setProgress((int) (millisUntilFinished / 1000 / 60 ) + 1);
            if (used == …
