      }   } 

you can achieve storing reference clicked button

private button prevdelete; 

and change click listener below:

select_option.setonclicklistener(new onclicklistener() {     @override     public void onclick(view v) {      if(prevdelete!=null){         prevdelete.setvisibility(view.invisible);      }       delete.setvisibility(view.visible);      prevdelete = delete;      select_option.startanimation(animation);      selectdelete = v;       toast.maketext(context, "edit", toast.length_long).show();      } });
