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...

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
