android - Scroll multiple recyclerviews on one recyclerview scroll -


i have arraylist of recyclerveiws in recyclerview , want know how scroll of them when 1 scrolled.
have far, gives me stack overflow error:

holder.rv.setonscrolllistener(new recyclerview.onscrolllistener() {             @override             public void onscrollstatechanged(recyclerview recyclerview, int newstate) {                 super.onscrollstatechanged(recyclerview, newstate);             }              @override             public void onscrolled(recyclerview recyclerview, int dx, int dy) {                 super.onscrolled(recyclerview, dx, dy);                 if (dx != -199382734)                     (sched_vh vh : vhs) {                         if (vh != holder)                             vh.rv.scrollby(-199382734, dy);                     }             }         }); 

i have worked on problem friend few hours..the final answer simple. main idea 2 recyclerviews should use same onscrolllistener instead of different ones, listener recyclerview scrolling, , avoid stack on flow. please try following

    //rcv , leftrcv 2 recyclerviews     recyclerview.onscrolllistener scrolllistener = new recyclerview.onscrolllistener() {     @override     public void onscrolled(recyclerview recyclerview, int dx, int dy) {             if (recyclerview == leftrcv) {                 rcv.removeonscrolllistener(this);                 rcv.scrollby(0, dy);                 rcv.addonscrolllistener(this);             } else if (recyclerview == rcv) {                 leftrcv.removeonscrolllistener(this);                 leftrcv.scrollby(0, dy);                 leftrcv.addonscrolllistener(this);             }         }          @override         public void onscrollstatechanged(recyclerview recyclerview, int newstate) {             super.onscrollstatechanged(recyclerview, newstate);         }     };      leftrcv.addonscrolllistener(scrolllistener);     rcv.addonscrolllistener(scrolllistener); 

but don't know whether result in performance issue...
