my oncreate method

public view oncreateview(layoutinflater inflater, viewgroup container,             bundle savedinstancestate) {          view rootview = inflater.inflate(r.layout.tab_one_calorie_consumed, container, false);          _calendar = calendar.getinstance(locale.getdefault());         month = _calendar.get(calendar.month) + 1;         year = _calendar.get(calendar.year);         log.d(tag, "calendar instance:= " + "month: " + month + " " + "year: "                 + year);          selecteddaymonthyearbutton = (button) this.getview().findviewbyid(r.id.selecteddaymonthyear);         selecteddaymonthyearbutton.settext("selected: ");          prevmonth = (imageview) this.getview().findviewbyid(r.id.prevmonth);         prevmonth.setonclicklistener(this);          currentmonth = (textview) this.getview().findviewbyid(r.id.currentmonth);         currentmonth.settext(dateformat.format(datetemplate,                 _calendar.gettime()));          nextmonth = (imageview) this.getview().findviewbyid(r.id.nextmonth);         nextmonth.setonclicklistener(this);          calendarview = (gridview) this.getview().findviewbyid(r.id.calendar);          // initialised         adapter = new gridcelladapter(getactivity().getapplicationcontext(),                 r.id.calendar_day_gridcell, month, year);         adapter.notifydatasetchanged();         calendarview.setadapter(adapter);         return rootview;     }

i have check twice nothing should null. working if using directly in main activity.

change

  selecteddaymonthyearbutton = (button) this.getview().findviewbyid(r.id.selecteddaymonthyear);

to

  selecteddaymonthyearbutton = (button) rootview.findviewbyid(r.id.selecteddaymonthyear);

and same other views.
