java - onClickListener in RecyclerView.ViewHolder -

i've got recyclerview.viewholder , recyclerview.adapter, need after click on item , send information item activity.

placesadapter.java

public class placesadapter extends recyclerview.adapter<placesviewholder> { private placesactivity placesactivity;      context context;     private int position;     list<places> places;      public placesadapter(list<places> places) {         this.places = places;}      @override     public void onattachedtorecyclerview(recyclerview recyclerview) {         super.onattachedtorecyclerview(recyclerview);     }      @override     public placesviewholder oncreateviewholder(viewgroup viewgroup, int i) {         view v = layoutinflater.from(viewgroup.getcontext()).inflate(r.layout.places_view, viewgroup, false);         placesviewholder pvh = new placesviewholder(v);         return pvh;     }      @override     public void onbindviewholder(placesviewholder personviewholder, int i) {         personviewholder.name.settext(places.get(i).name);         personviewholder.address.settext(places.get(i).address);         picasso.with(personviewholder.itemview.getcontext())                 .load(places.get(i).photo)                 .into(personviewholder.getphoto());        }      @override     public int getitemcount() {         return places.size();     }  } 

placesviewholder.java

in line "intent.putextra(placesdetail.places_name,);" how can send name?

 public  class placesviewholder extends recyclerview.viewholder {      cardview cv;     public textview name;     public textview address;     public imageview photo;     public placesviewholder(final view itemview) {         super(itemview);         cv = (cardview)itemview.findviewbyid(r.id.cv);         name = (textview)itemview.findviewbyid(r.id.person_name);         address = (textview)itemview.findviewbyid(r.id.person_age);         photo = (imageview)itemview.findviewbyid(r.id.person_photo);          itemview.setonclicklistener(new view.onclicklistener(){              @override             public void onclick(view v) {                 context context = v.getcontext();                 intent intent = new intent(context, placesdetail.class);                 intent.putextra(placesdetail.places_name,);                 context.startactivity(intent);             }         });      }      public textview getaddress() {         return address;     }      public textview getname() {         return name;     }     public imageview getphoto() {         return photo;     } } 

this complete example of custom adapter i'm able details of particular items. in mainactivity need set adapter :

adapter = new myadapter(getapplicationcontext(), account_no, title, afn1, aln1,afn2, aln2,afn3, aln3,isavilable,waitlist,flag);                             adapter.notifydatasetchanged();                             mrecyclerview.setadapter(adapter); 

now see code custom adapter :

 public class myadapter extends recyclerview.adapter<myadapter.viewholder> {     string tag = "myadapter";     context context;     private string[] accountno;     private string[] title;     private string[] afn1;     private string[] aln1;     private string[] afn2;     private string[] aln2;     private string[] afn3;     private string[] aln3;     private string[] isavailable;     private string[] waitlist;     private int flag;  public static class viewholder extends recyclerview.viewholder {         public textview account_no,title,afn1,afn2,aln1,aln2,color,is_available;         private imageview img_android;         cardview cardview;         public viewholder(cardview v) {             super(v);             account_no = (textview)v.findviewbyid(r.id.acctno);             title = (textview)v.findviewbyid(r.id.title);             afn1 = (textview) v.findviewbyid(r.id.afn1);             cardview = v;         }     }     // provide suitable constructor (depends on kind of dataset)     public myadapter(context context, string[] accountno,string[] title,string[] afn1,string[] aln1,string[] afn2,string[] aln2,string[] afn3,string[] aln3,string[] isavailable, string[] waitlist,int flag) {         this.context = context;         this.accountno = accountno;         this.title = title;         this.afn1 = afn1;         this.aln1 = aln1;         this.afn2 = afn2;         this.aln2 = aln2;         this.afn3 = afn3;         this.aln3 = aln3;         this.isavailable = isavailable;         this.waitlist = waitlist;         this.flag = flag;         log.d(tag,afn1.tostring() +aln1+afn2+aln2+afn3+aln3.tostring()+waitlist);     }     @override     public viewholder oncreateviewholder(viewgroup parent,int viewtype) {         cardview cv = (cardview) layoutinflater.from(parent.getcontext()).inflate(r.layout.list_item, parent, false);         return new viewholder(cv);     }     @override     public void onbindviewholder(final viewholder holder, final int position) {         final cardview cardview = holder.cardview;         final textview accountno = (textview)cardview.findviewbyid(r.id.acctno);         accountno.settext(accountno[position]);         final textview titletxt = (textview)cardview.findviewbyid(r.id.title);         titletxt.settext(title[position]);         final textview afn1txt = (textview) cardview.findviewbyid(r.id.afn1);         afn1txt.settext(afn1[position]+" "+aln1[position]);         log.d(tag,waitlist[position]);         cardview.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 int id = getitemviewtype(position);                 sharedpreferences sharedpreferences = context.getsharedpreferences(constant.mypreference,context.mode_private);                 sharedpreferences.editor edit = sharedpreferences.edit();                 edit.putstring(constant.account,accountno[position]);                 edit.putstring(constant.title,title[position]);                 edit.putstring(constant.afn1,afn1[position]);                 edit.putstring(constant.aln1,aln1[position]);                 edit.putstring(constant.afn2,afn2[position]);                 edit.putstring(constant.aln2,aln2[position]);                 edit.putstring(constant.afn3,afn3[position]);                 edit.putstring(constant.aln3,aln3[position]);                 edit.putboolean(constant.is_available, boolean.parseboolean(isavailable[position].touppercase()));                 edit.putstring(constant.waitlist,waitlist[position]);                 log.d("waitingno2 :",""+string.valueof(waitlist[position]));                 edit.commit();                 intent intent = new intent(v.getcontext(), detailsactivity.class);                 v.getcontext().startactivity(intent);             }         });     }      // return size of dataset (invoked layout manager)     @override     public int getitemcount() {         return accountno.length;     } } 

after value sharedpreferences in activity called on card click:

preferences = getsharedpreferences("myshared", context.mode_private); accountno = sharedpreferences.getstring(constant.account,null).touppercase();             title = sharedpreferences.getstring(constant.title,null).touppercase();             afn1 = sharedpreferences.getstring(constant.afn1,null).touppercase();             aln1 = sharedpreferences.getstring(constant.aln1,null).touppercase();             afn2 = sharedpreferences.getstring(constant.afn2,null).touppercase();             aln2 = sharedpreferences.getstring(constant.aln2,null).touppercase();             afn3 = sharedpreferences.getstring(constant.afn3,null).touppercase();             aln3 = sharedpreferences.getstring(constant.aln3,null).touppercase();             isavailable = sharedpreferences.getboolean(constant.is_available,isavailable);             waitlist = sharedpreferences.getstring(constant.waitlist,waitlist); 

now whatever want , enjoy code.
