and below adapter code:

public class getjobdetailsadapter  extends recyclerview.adapter<getjobdetailsadapter.myviewholder> {     public list<getjobdetailsjobs> detailsjob;     public  class myviewholder extends recyclerview.viewholder{          public textview about_company,designation,eligibility,joblocation,jobdescription,keyskills,eventdate,eventlocation,salary,comp_name;         public myviewholder(view view){             super(view);             about_company=(textview) view.findviewbyid(r.id.about_company);             designation=(textview) view.findviewbyid(r.id.designation);             eligibility=(textview) view.findviewbyid(r.id.eligibility);             joblocation=(textview) view.findviewbyid(r.id.joblocation);             jobdescription=(textview) view.findviewbyid(r.id.jobdescription);             keyskills=(textview) view.findviewbyid(r.id.keyskills);             eventdate=(textview) view.findviewbyid(r.id.eventdate);             eventlocation=(textview) view.findviewbyid(r.id.eventlocation);             salary=(textview) view.findviewbyid(r.id.salary);             comp_name=(textview) view.findviewbyid(r.id.comp_name);         }     }     public getjobdetailsadapter(list<getjobdetailsjobs>detailsjob){         this.detailsjob=detailsjob;     }     @override     public myviewholder oncreateviewholder(viewgroup parent, int viewtype) {         view itemview = layoutinflater.from(parent.getcontext())                 .inflate(r.layout.jobdetails, parent, false);          return new myviewholder(itemview);     }     @override     public void onbindviewholder(myviewholder holder, int position) {         getjobdetailsjobs b1 = detailsjob.get(position);         holder.about_company.settext(b1.getabout_company());         holder.designation.settext(b1.getdesignation());         holder.eligibility.settext(b1.geteligibility());      }      @override     public int getitemcount() {         return detailsjob.size();     } } 

you not setting adapter recyclerview in code. "recyclerview.setadapter(gadapter)" set either in oncreate or in ajax callback .

   recyclerview.setadapter(gadapter) 

after jobdetails ajax callback have set adapter.

gadapter.setjobdetailsadapterdata(your_jobs_data); 

then set data , call notifydatasetchanged.

adapter: should setjobdetailsadapter.

public void setjobdetailsadapterdata(list<getjobdetailsjobs>detailsjob){         this.detailsjob=detailsjob;         notifydatasetchanged();     }
