android - RecyclerView with Glide causing NullPointer after scrolling up again -


here adapter class:

@override public recyclerview.viewholder oncreateviewholder(viewgroup parent, int viewtype) {          view view = inflater.inflate(r.layout.container_accommodation,parent,false);         myholder holder = new myholder(view);         holder.setisrecyclable(false);         return holder;     }   @override  public void onbindviewholder(recyclerview.viewholder holder, final int position) {          myholder myholder= (myholder) holder;         accommodation current = data.get(position);         picasso.with(context).load("http://10.0.2.2:18180/aafs/accommodations/"+current.accommoid+"/accomm_images/"+current.accommomainimage.imagename)                .error(r.drawable.error)                 .into(myholder.imageview);      }

here error when try scroll up again, scrolling down works fine.

any great.

thanks.

did override getitemcount method in adapter?

@override public int getitemcount(){     return data.size(); }

it seems onbindviewholder(vh holder, int position) method supplying invalid position parameter. when accommodation data collection returns null. type of collection using hold accommodations?
