now wants update textview @ instant checkbox clicked in listview till doest not desired when scroll downwards , take alook on checked item textview updated

please help me in advance

istesd use

holder.ckbox.settext(checkeditems[position]?"added","add");

and remove

holder.tvckboxtext.settext(ckboxtextadd[position]?"added","add"););

this because might not back upwards landscape view
