Recycler View update few row every x sec
<p>i have view pager . view pager have 3 section/tabs which have same fragments .fragment contains recycleview. 
in recyclerview i have custom layout for row . row contain textview and imagers . for textview its timer which should update every 1 sec . so for now i am using timer with fixe schedule task</p>

<pre><code> Timer timer = new Timer();
  timer.scheduleAtFixedRate( new TimerTask() {
        public void run() {

             textview.settext(updatedvalue);

         }
        }, 0, 1000);
</code></pre>

<p>i am doing this in bindViewHolder . but now problem is this timer is applicable for only few rows of recycle view . 
 so in this it always call inrespect of that row is visible or not </p>

<p>so say i have total 30 rows and timer is applicable for 1st 4 row (this can be any value depend upon server value) . so how i can do this updating stuff for that row only . which my code is happing for all row so its taking to much memory </p>
