android - RecyclerView Adapter gives error "The hierarchy of the type RecycleAdapter is inconsistent" -

i trying add new recyclerview project inside fragement. following video tutorial on link1 . when try create adapter recyclerview, start getting error. using eclipse juno. cant figure out problem. please help

my code:

public class recycleadapter extends recyclerview.adapter<recycleadapter.myviewholder> {  private layoutinflater inflator; list <item> data = collections.empty_list;  public recycleadapter(context context, list<item> data){     inflator = layoutinflater.from(context); }  @override public int getitemcount() {     // todo auto-generated method stub     return data.size(); }   @override public myviewholder oncreateviewholder(viewgroup parent, int arg1) {     view view = inflator.inflate(r.layout.row_staggered_new, parent, false);     myviewholder holder = myviewholder(view);     return holder; }  @override public void onbindviewholder(myviewholder holder, int position) {     item current = data.get(position);     holder.text.settext(current.title);     holder.image.setimageresource(current.image);  }  public static class myviewholder extends recyclerview.viewholder{      public imageview image;     public textview text;      public myviewholder(view itemview) {         super(itemview);         image = (imageview) itemview.findviewbyid(r.id.imageview1);         text = (textview) itemview.findviewbyid(r.id.textview1);     } } } 

both myviewholder , recycleadapter giving error "the hierarchy of type recycleadapter inconsistent". in extends part of recycleadapter, shows error "bound mismatch: type recycleadapter.myviewholder not valid substitute bounded parameter <vh extends recyclerview.viewholder> of type recyclerview.adapter<vh>".

any pointers?
