Answer 1

After 6 hours I finally found how to use it. However, I couldn't find the same way with the Runnable.

I'm using this code and it works for me:

@Override
public void onBindViewHolder(@NonNull final ViewHolder holder, final int position) {
    try {
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        Date event_date = dateFormat.parse(laterStart.toString());
        current_date = dateFormat.parse(laterCurrent.toString());
        Date diff = event_date.getTime() - current_date.getTime();

    } catch (Exception e) {
        e.printStackTrace();
    }

    //Very important code for some problems
    if (holder.timer != null) {
        holder.timer.cancel();
    }

    holder.timer = new CountDownTimer(diff, 900) {
        @Override
        public void onTick(long millisUntilFinished) {
            long day = TimeUnit.MILLISECONDS.toDays(millisUntilFinished);
            millisUntilFinished -= TimeUnit.DAYS.toMillis(day);

            long hour = TimeUnit.MILLISECONDS.toHours(millisUntilFinished);
            millisUntilFinished -= TimeUnit.HOURS.toMillis(hour);

            long minute = TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished);
            millisUntilFinished -= TimeUnit.MINUTES.toMillis(minute);

            long second = TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished);


            holder.timeText.setText(day+":"+hour+":"+minute+":"+second);
        }

        @Override
        public void onFinish() {
        }
    }.start();
}

And RecycleView ViewHolder class:

public class ViewHolder extends RecyclerView.ViewHolder {
***your codes***

   //Just add CountDownTimer
   CountDownTimer timer;

*** your codes ***
}
