Question

所以我的日程安排片段代码如下所示。这些代码是从我的later error修复的，但问题是，一旦我点击导航抽屉中的"My Schedule"，它就会出现无响应错误。请记住，我的Schedule Fragment自己连接到Navigation Drawer。

@TargetApi(Build.VERSION_CODES.N)
public class ScheduleFragment extends Fragment {

CompactCalendarView compactCalendar;
private SimpleDateFormat dateFormatMonth = new SimpleDateFormat("MMM - yyyy", Locale.getDefault());


public ScheduleFragment() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState){
    // Inflate the layout for this fragment
    View v = inflater.inflate(R.layout.fragment_schedule, container, false);

    final ActionBar actionBar = ((AppCompatActivity) getActivity()).getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(false);
    actionBar.setTitle(null);

    compactCalendar = (CompactCalendarView) v.findViewById(R.id.compactcalendar_view);
    compactCalendar.setUseThreeLetterAbbreviation(true);

    Event ev1 = new Event(Color.RED, 1477040400000L, "Teachers' Professional Day");
    compactCalendar.addEvent(ev1);

    compactCalendar.setListener(new CompactCalendarView.CompactCalendarViewListener() {
        @Override
        public void onDayClick(Date dateClicked) {
            Context c = getContext().getApplicationContext();

            if (dateClicked.toString().compareTo("Fri Oct 21 00:00:00 AST 2016") == 0) {
                Toast.makeText(c, "Teachers' Professional Day", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(c, "No Events Planned for that day", Toast.LENGTH_SHORT).show();
            }
        }

        @Override
        public void onMonthScroll(Date firstDayOfNewMonth) {
            actionBar.setTitle(dateFormatMonth.format(firstDayOfNewMonth));
        }
    });
return v;
}

}

似乎有什么问题？我是否需要实施"extends ActionBarActivity"或"AppCompatActivity"？这些中的任何一个都会导致错误@Override method.

由于片段代码
