java - Cannot access method by reference -

when access method directly on pageradapter creation have getviewatposition() method. when try using reference, can't. may acecces reference?

here can: 1:

here can't: 2:

public class cardapioru extends fragment {  private viewpager mpager; private pageradapter mpageradapter;  @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     viewgroup rootview = (viewgroup) inflater.inflate(r.layout.view_pager_ru, container, false);      mpager = (viewpager) rootview.findviewbyid(r.id.pager);     mpageradapter = new pageradapterru(inflater);     mpager.setadapter(mpageradapter);     return rootview; }  } 

.

public class pageradapterru extends pageradapter {  private view domingo = null; private view segunda = null;  @suppresslint("inflateparams") public pageradapterru(layoutinflater inflater) {     domingo = inflater.inflate(r.layout.ru_domingo, null);     segunda = inflater.inflate(r.layout.ru_segunda, null); }  public view getviewatposition(int position) {     view view = null;     if (position == 0) {         view = domingo;     }     if (position == 1) {         view = segunda;     }     ;     return view; };  @override public object instantiateitem(view collection, int position) {     view view = getviewatposition(position);     ((viewpager) collection).addview(view, 0);     return view; }  @override public int getcount() {     return 2; } 

getviewatposition() method of pageradapterru.

on first screenshot you're calling method directly on pageradapterru instance, on second screenshot you're calling on pageradapter.

it doesn't matter how you've initialized it, you've declared pageradapter, have access methods of pageradapter.

to have access methods of subclass, declare type of subclass.

change following:

private pageradapter mpageradapter; 

to this:

private pageradapterru mpageradapter; 

and you'll able call getviewatposition() on mpageradapter.
