and detail explanation great pleasure me.

i must solve problem.

thanks watching post.

when scroll, setoncheckedchangelistener called. handle in view need below -

holder.checkbox.setoncheckedchangelistener(null); holder.checkbox.setchecked(_songs.get(position).isselected());

you first need set onchecked null on scroll when view getting populated , assigning views, don't call oncheckedlistener.

and need call oncheckedchangelistener

 holder.checkbox.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                  if (holder.checkbox.ischecked()) {                      check_flag_arr[position] = true;                 } else {                     check_flag_arr[position] = false;                 }             }         });
