android - listview adapter doesnt want to set text -

ok trying simple listview filling array adapter have:

public class mainactivity extends activity {

string[] dish = {"soup", "rice", "grecha", "potato"};  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.lunch);      setrequestedorientation(activityinfo.screen_orientation_landscape);      setcontentview(r.layout.lunch);     listview lunchlv = (listview)findviewbyid(r.id.lunchlv);     cafeadapter ca = new cafeadapter();     lunchlv.setadapter(ca);  }   public class cafeadapter extends baseadapter {      @override     public int getcount() {         return dish.length;     }      @override     public object getitem(int i) {         return null;     }      @override     public long getitemid(int i) {         return 0;     }      @override     public view getview(int i, view view, viewgroup viewgroup) {        view = getlayoutinflater().inflate(r.layout.list, null);         textview title = (textview) findviewbyid(r.id.title);         title.settext(dish[i]);         return view;     } } 

}

i have list.xml file , lunch.xml file

for weird reasons title.settext(dish[i]); produces error , makes program crash. have element id "title in xml file anyways java.lang.nullpointerexception: attempt invoke virtual method 'void android.widget.textview.settext(java.lang.charsequence)' on null object reference.

do have ideas doing wrong?

you should use

textview title = (textview) view.findviewbyid(r.id.title); 

instead:

 textview title = (textview) findviewbyid(r.id.title);
