finally i've been able solve problem teacher helped. have changed move listener onbindviewholder viewholder class this:
public class studentadapter extends recyclerview.adapter<studentadapter.studentviewholder> { private layoutinflater inflator; private int status; typeface typeface; list<student> students = collections.emptylist(); public studentadapter(context context, list<student> students, string font) { inflator = layoutinflater.from(context); this.students = students; typeface = typeface.createfromasset(context.getassets(), font); } @override public studentviewholder oncreateviewholder(viewgroup parent, int viewtype) { view view = inflator.inflate(r.layout.student_row, parent, false); studentviewholder studentviewholder = new studentviewholder(view); return studentviewholder; } @override public void onbindviewholder(final studentviewholder holder, final int position) { final student currentstudent = students.get(position); holder.studentname.settext(currentstudent.student); holder.chbillegal.settag(students.get(position)); holder.edittext.settag(students.get(position)); holder.edittext.settext(currentstudent.getagaints_rule()); if (currentstudent.isselected()) { holder.edittext.setenabled(true); }else{ holder.edittext.setenabled(false); } holder.chbillegal.setchecked(students.get(position).isselected()); if (currentstudent.getstatus() == 1) { holder.chbpresent.setchecked(true); } else if (currentstudent.getstatus() == 0) { holder.chbpresent.setchecked(false); } } @override public int getitemcount() { return students.size(); } class studentviewholder extends recyclerview.viewholder { textview studentname; checkbox chbpresent, chbillegal; edittext edittext; public studentviewholder(view itemview) { super(itemview); studentname = (textview) itemview.findviewbyid(r.id.studentlisttext); this.studentname.settypeface(typeface); edittext = (edittext) itemview.findviewbyid(r.id.edtagaintsrule); chbpresent = (checkbox) itemview.findviewbyid(r.id.chbpresent); chbillegal = (checkbox) itemview.findviewbyid(r.id.chbillegal); chbillegal.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { checkbox cb = (checkbox) v; student s = (student) v.gettag(); log.e("gexam", string.valueof(cb.ischecked())); s.setselected(cb.ischecked()); studentviewholder.this.edittext.setenabled(cb.ischecked()); } }); edittext.addtextchangedlistener(new textwatcher() { @override public void beforetextchanged(charsequence s, int start, int count, int after) { } @override public void ontextchanged(charsequence s, int start, int before, int count) { } @override public void aftertextchanged(editable s) { student student = (student) studentviewholder.this.edittext.gettag(); student.setagaints_rule(s.tostring()); } }); } } public list<student> getstudentlist() { return students; } }
