android - How to keep the status of the ViewHolder in RecyclerView -

i have recyclerview includes few grid cells. there textview above click me button. i'll show example, name @ textview when button clicked. problem me text inside textview not persistent.

here code in mainactivity:

private void initializedata(){     persons = new arraylist<>();     persons.add(new person("name 1", "23 years old", r.drawable.a));     persons.add(new person("name 2", "25 years old", r.drawable.b));     persons.add(new person("name 3", "35 years old", r.drawable.c));     persons.add(new person("name 4", "35 years old", r.drawable.c));     persons.add(new person("name 5", "35 years old", r.drawable.c));     persons.add(new person("name 6", "35 years old", r.drawable.c));     persons.add(new person("name 7", "35 years old", r.drawable.c));     persons.add(new person("name 8", "35 years old", r.drawable.c));     persons.add(new person("name 9", "35 years old", r.drawable.c)); }  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      recyclerview  = (recyclerview)findviewbyid(r.id.my_recycler_view);     recyclerview.sethasfixedsize(true);      layoutmanager = new gridlayoutmanager(this, 1, linearlayoutmanager.horizontal, false);     recyclerview.setlayoutmanager(layoutmanager);     recyclerview.setitemanimator(new defaultitemanimator());      persons = new arraylist<>();     initializedata();      rvadapter adapter = new rvadapter(persons);     recyclerview.setadapter(adapter);      adapter.notifydatasetchanged(); } 

code in adapter:

public class rvadapter extends recyclerview.adapter<rvadapter.personviewholder>{  list<person> persons;  rvadapter(list<person> persons){     this.persons = persons; }  @override public personviewholder oncreateviewholder(viewgroup viewgroup, int i) {     view v = layoutinflater.from(viewgroup.getcontext()).inflate(r.layout.cards_layout, viewgroup, false);     personviewholder pvh = new personviewholder(v);     return pvh; }  @override public void onbindviewholder(personviewholder personviewholder, int i) {     personviewholder.personname.settext(persons.get(i).name);     personviewholder.personage.settext(persons.get(i).age);     personviewholder.personphoto.setimageresource(persons.get(i).photoid);      final personviewholder vh = personviewholder;     personviewholder.button.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             vh.textview.settext(vh.personname.gettext().tostring());         }     }); }  @override public void onattachedtorecyclerview(recyclerview recyclerview) {     super.onattachedtorecyclerview(recyclerview); }  @override public int getitemcount() {     return persons.size(); }  public static class personviewholder extends recyclerview.viewholder {     cardview cv;     public textview personname;     public textview personage;     imageview personphoto;     public textview textview;     public button button;      personviewholder(view itemview) {         super(itemview);         cv = (cardview)itemview.findviewbyid(r.id.cv);         personname = (textview)itemview.findviewbyid(r.id.person_name);         personage = (textview)itemview.findviewbyid(r.id.person_age);         personphoto = (imageview)itemview.findviewbyid(r.id.person_photo);         textview = (textview)itemview.findviewbyid(r.id.text);         button = (button)itemview.findviewbyid(r.id.button);     } } } 

i think reason viewholder recreated. how deal kind of situation? thanks.

you can add boolean isshowname model person, in onbindviewholder() method:

... personviewholder.button.setonclicklistener(new view.onclicklistener() {     @override     public void onclick(view v) {         vh.textview.settext(vh.personname.gettext().tostring());         persons.get(i).setisshowname(true); // don't forget!     } });  if (persons.get(i).isshowname()) {     vh.textview.settext(vh.personname.gettext().tostring()); } else {     vh.textview.settext(""); }
