Android 如何在RecyclerView中处理多个倒计时器？

我有一个

回收视图

，我需要在每一行上显示一个倒计时

这里有一个类似的问题 它有一个很好的解决方案，但我需要使用recyclerview

编辑：

import android.os.CountDownTimer;
import android.support.v7.widget.RecyclerView;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import java.util.ArrayList;

public class Adapter extends RecyclerView.Adapter{

private ArrayList al_data;

public class MyViewHolder extends RecyclerView.ViewHolder{
    public TextView tv_timer;
    CountDownTimer timer;

    public MyViewHolder (View view){
        super(view);
        tv_timer = (TextView)view.findViewById(R.id.tv_timer);

    }


}

public Adapter(ArrayList al_data) {
    this.al_data = al_data;
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.adapter_layout,parent,false);


    return new MyViewHolder(view);
}

@Override
public void onBindViewHolder(final MyViewHolder holder, int position) {

    holder.tv_timer.setText(al_data.get(position));

    if (holder.timer != null) {
        holder.timer.cancel();
    }
     long timer = Long.parseLong(al_data.get(position));

    timer = timer*1000;

    holder.timer = new CountDownTimer(timer, 1000) {
        public void onTick(long millisUntilFinished) {
          holder.tv_timer.setText("" + millisUntilFinished/1000 + " Sec");
        }

        public void onFinish() {
            holder.tv_timer.setText("00:00:00");
        }
    }.start();


}

@Override
public int getItemCount() {
    return al_data.size();
}

}

这是我的代码适配器
