Recyclerview with multiple countdown timers causes flickering

thanx Hammad Tariq Sahi i have used your logic and solve my problem in this way….i have also refereed this link

in my adapter

ArrayList<ViewHolder> viewHoldersList;
    private Handler handler = new Handler();
    private Runnable updateRemainingTimeRunnable = new Runnable() {
        @Override
        public void run() {
            synchronized (viewHoldersList) {
                for (ViewHolder holder : viewHoldersList) {
                    holder.updateTimeRemaining();
                }
            }
        }
    };

inside constructor of my adapter

viewHoldersList = new ArrayList<>();
startUpdateTimer();

and added this method to calculate time

private void startUpdateTimer() {
        Timer tmr = new Timer();
        tmr.schedule(new TimerTask() {
            @Override
            public void run() {
                handler.post(updateRemainingTimeRunnable);
            }
        }, 1000, 1000);
    }

added two methods to my viewholder class

public void setData(Product product){
            this.product = product;
        }
        public void updateTimeRemaining() {
            if(product.getProductType().equalsIgnoreCase("Auction Product")) {
                Log.e("hetal",product.getProductType());
                try {
                    String start = product.getStart();
                    String stop = product.getStop();

                    //txt_timeleft.setText("");
                    SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

                    Calendar start_date = Calendar.getInstance();
                    start_date.setTime(format.parse(start));

                    Calendar end_date = Calendar.getInstance();
                    end_date.setTime(format.parse(stop));

                    final Calendar today = Calendar.getInstance();
                    CountDownTimer timer;

                    long timeDiff = end_date.getTimeInMillis() - today.getTimeInMillis();
                    if (timeDiff > 0) {
                        long seconds = timeDiff / 1000 % 60;
                        long minutes = timeDiff / (60 * 1000) % 60;
                        long hours = timeDiff / (60 * 60 * 1000) % 24;
                        //long days = (int) diff / (24 * 60 * 60 * 1000);
                        long days = TimeUnit.MILLISECONDS.toDays(timeDiff);


                        String left = "";
                        if (days > 0)
                            left += days + " " + context.getString(R.string.txt_day) + " ,";
                        if (hours > 0)
                            left += hours + " " + context.getString(R.string.txt_hour) + " ,";
                        if (minutes > 0)
                            left += minutes + " " + context.getString(R.string.txt_minute) + " ,";

                        left += seconds + " " + context.getString(R.string.txt_second);

                        final String finalLeft = left;
                        txt_timeleft.setText(finalLeft);
                    } else {
                        txt_timeleft.setText("Time Out !!");
                    }
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
            }
        }

and finally inside onBindViewHolder

synchronized (viewHoldersList) {
                viewHolder.setData(product);
                if(viewHoldersList.size()< (list.size()-2)) viewHoldersList.add(viewHolder);
            }

works perfect….thanx all
