Load state of particular recyclerview item

so I have recyclerview populated with data from database. Each row contains two buttons one for play and second for stop time. So what I'm trying is to save state of buttons inside recyclerview. And I used

PreferenceManager.getDefaultSharedPreferences(context).edit().                                 putInt(Constants.numberOfbutton, getAdapterPosition()).apply(); 

to save particular position. I have inserted that line of code inside button click and I checked it's saving correct position. What I'm trying to achieve is, when user enters the app after closing if he lefts any of the buttons in play mode to restore that state and continue timer. But problem is when user enters the app all buttons are running. I'm using chronometer for presentation of the time. I think here is the problem in this method:

 private void startTime(int position ) {         Data data = datas.get(position);         chronometer.setBase(SystemClock.elapsedRealtime() + Long.parseLong(data.getTime()));         chronometer.start();      } 

UPDATE EXPLANATION:

So I can load from database for each item of recyclerview it's time, date, name etc. But I can't figure it out how to play chronometer of just particular item when user enters the app again. NOTE AGAIN: I'm performing correct saving getAdapterAtPosition and loading data from PreferenceManager. I've checked that. Even I tried putting the number of one of rows but same issue appears. Any help very appreciated. Thanks.

I have found the answer. I save the boolean in database actually I used 1 or 0 than parse that to true or false acordingly is button play pressed or not. Thank you all for your comments and trying to help.

Try to use handler or alarm service instead of chronometer
