运行我的caldroid片段时出现此错误：
android.view.InflateException: Binary XML file line #15: Error inflating class fragment
知道那可能是什么？ 我已经看到了这个问题的其他帖子，但对我没什么用。
我在caldroid片段中的代码是这样的：
public class Caldroid_fragment extends Fragment{
private DataBaseHelper myDB;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.caldroid_calendar, container, false);
return rootView;
}
@RequiresApi(api = Build.VERSION_CODES.N)
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
myDB = new DataBaseHelper(getContext());
ColorDrawable blue = new ColorDrawable(Color.BLUE);
CaldroidFragment caldroidFragment = new CaldroidFragment();
Bundle args = new Bundle();
args.putInt(CaldroidFragment.START_DAY_OF_WEEK, CaldroidFragment.MONDAY);
caldroidFragment.setArguments(args);
java.util.Calendar cal = Calendar.getInstance();
args.putInt(CaldroidFragment.MONTH, cal.get(Calendar.MONTH) + 1);
args.putInt(CaldroidFragment.YEAR, cal.get(Calendar.YEAR));
caldroidFragment.setArguments(args);
for(int i=0;i<myDB.getLastId();i++) {
String dt = myDB.getDates(i);
java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("dd-MM-yyyy");
Date teste = null;
try {
teste = sdf.parse(dt);
} catch (ParseException e) {
e.printStackTrace();
}
caldroidFragment.setBackgroundDrawableForDate(blue,teste);
}
FragmentTransaction t = getChildFragmentManager().beginTransaction();
t.replace(R.id.caldroidCal, caldroidFragment);
t.commit();
}
}

使用片段的活动的XML：
