ListView and items with countdown timer

Question

I solved this differently in my case. Instead of having a timer handler set inside your getView(), I just set the time difference between the current time and your desired time to the TextView every time getView() is called. So move this code of yours back inside getView():

long outputTime = Math.abs(promoAction.timer_end
                    - System.currentTimeMillis());
Date date = new java.util.Date(outputTime);
String result = new SimpleDateFormat("hh:mm:ss").format(date);
tv.setText(result);

Then create a handler in the activity to call notifyDatasetChanged() every one minute on the listview's adapter:

Handler timerHandler = new Handler();
Runnable timerRunnable = new Runnable() {
    @Override
    public void run() {
        myAdapter.notifyDataSetChanged();
        timerHandler.postDelayed(this, 60000); //run every minute
    }
};

I stop this handler on onPause():

@Override
protected void onPause() {
    timerHandler.removeCallbacks(timerRunnable);
    super.onPause();
}

And I start it again on onResume():

@Override
protected void onResume() {
    timerHandler.postDelayed(timerRunnable, 500);
    super.onResume();
}

And that's it. :)

Hope it helps.
