android - Show menu in Google Glass -

hi having problem creating menu on regular cards in immersion. have far:

i have cardscrolladapter implements onitemclicklistener this:

private class examplecardscrolladapter extends cardscrolladapter implements onitemclicklistener {

    @override     public int findidposition(object id) {         return -1;     }      @override     public int finditemposition(object item) {         return mcards.indexof(item);     }      @override     public int getcount() {         return mcards.size();     }      @override     public object getitem(int position) {         return mcards.get(position);     }      @override     public view getview(int position, view convertview, viewgroup parent) {          view rowview = convertview;         viewholder holder;          if(rowview==null) {             rowview = minflater.inflate(r.layout.card_layout, null);             holder = new viewholder();             holder.maintext = (textview) rowview.findviewbyid(r.id.tvmaintext);             holder.fullimage = (imageview) rowview.findviewbyid(r.id.fullimage);             holder.image1=(imageview) rowview.findviewbyid(r.id.ivimage1);             holder.image2 = (imageview) rowview.findviewbyid(r.id.ivimage2);             holder.image3 = (imageview) rowview.findviewbyid(r.id.ivimage3);             holder.llimages = (linearlayout) rowview.findviewbyid(r.id.llimages);             holder.llsecondaryimages = (linearlayout) rowview.findviewbyid(r.id.llsecondaryimages);             rowview.settag( holder );         } else holder = (viewholder) convertview.gettag();          customcard myobject = (customcard) getitem(position);          if (myobject.getcompanyinfo()!=null) {              system.out.println(myobject.getimageurl());             system.out.println(myobject.getcompanyinfo());              holder.maintext.settext(myobject.getcompanyinfo());             imageloader.displayimage(myobject.getimageurl(), holder.image1);              holder.maintext.setvisibility(imageview.visible);             holder.llimages.setvisibility(imageview.visible);             holder.image1.setvisibility(imageview.visible);          } else {             imageloader.displayimage(myobject.getimageurl(), holder.fullimage);             holder.llimages.setvisibility(imageview.visible);             holder.fullimage.setvisibility(imageview.visible);         }          holder.image2.setvisibility(imageview.gone);         holder.image3.setvisibility(imageview.gone);         holder.llsecondaryimages.setvisibility(imageview.gone);          return rowview;     }      public class viewholder {         public textview maintext;         public imageview fullimage;         public imageview image1;         public imageview image2;         public imageview image3;         public linearlayout llimages;         public linearlayout llsecondaryimages;     }      public void onitemclick(adapterview<?> parent, view view, int position, long id) {         system.out.println("click" + position);         oncreateoptionsmenu(null);      }  } 

and when tap cards prints "click" , position card works.

after want run oncreateoptionsmenu looks this:

@override public boolean oncreateoptionsmenu(menu menu) {     menuinflater inflater = getmenuinflater();     inflater.inflate(r.menu.card_menu, menu);     return true; } 

the problem having understanding how make oncreateoptionsmenu run? menu menu must supply onitemclick method instead of null?

you don't need separate activity case — should when need show menu live card.

the error in original onitemclick method: should calling openoptionsmenu display menu, not oncreateoptionsmenu.
