You can see My code for understanding the things:

super.onCreate(savedInstanceState);

}
private void init() {
mTimeTableDataList = new ArrayList<>();
mUserID = getArguments().getString(Constant.KEY_USERID);

if (mCurrDay == -1) {
mCurrDay = ((CreateTimetableActivity) getContext()).mTabItems.get(0).getDayID();
}
}

}
Note:I wanted to clear that i have seen links of stackoverflow which have same kind of problem and they did try to resolve. I also followed the step still issue is presist.
