Error: Cannot Find Symbol Method Getsupportactionbar(),findviewbyid(int),getapplicationcontext()

Solution 1:

In fragments, you can not directly call findViewById() and have to use the view that you just inflated and call findViewById() on it. So your onCreateView code will be,

@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragmentViewv= inflater.inflate(R.layout.fragment_schedule, container, false);
    compactCalendar = (CompactCalendarView) v.findViewById(R.id.compactcalendar_view); 
   //Make sure that the view inflated above has these view elements which you are trying to initialize
    .
    .
    .
    }

Similarly for getApplicationContext(), you first need to call getContext() and then call getApplicationContext() on it So it becomes,

Contextc= getContext().getApplicationContext();

Same goes for getSupportActionBar();

Solution 2:

In my opinion, you should inflate the view and use view.findViewByID(R.id.id), then call return at the end of the method .
