Chronometer in RecyclerView : Timer became 00:00:00 when scrolling

Question

I following this 1 ,2 an this 3 . I have an RecyclerView with CardView. I have add an timer using Chronometer. The aplication work like this:

There is first condition of CardView with Green Color. When User choose one, the color of change into Yellow.

I want make if the timer in 00:30:00(HH:MM:SS) the Color of CardView change color again into Blue. And when the timer in 01:00:00(HH:MM:SS), the color of CardView change again into Brown.

I following that tutor(above) But when i scroll down the RecyclerView , the timer (Choronometer) is became 00:00:00 again . I dont know where is the wrong.

Activity.java

private static final int THIRTYMINUTES = 1800000;
private static final int HOUR = 3600000;

int h,m,s;

Any answer will helpful for me. Thanks before
