我有我的日历的问题。 这里是code：

I have a problem with my calendar. Here is the code:

Calendar mCalendar = Calendar.getInstance();
mToday[0] = mCalendar.get(Calendar.DAY_OF_MONTH);
mToday[1] = mCalendar.get(Calendar.MONTH); // zero based
mToday[2] = mCalendar.get(Calendar.YEAR);

无法运行我的项目，因为AndroidStudio显示错误的Calendar.DAY_OF_MONTH，Calendar.MONTH等...我得到nullPointException在模拟器中运行，而

Can not run my project because AndroidStudio shows error on the Calendar.DAY_OF_MONTH, Calendar.MONTH etc... I get nullPointException while running in emulator

据最高审计机关的

必须是之一：   java.util.Calendar.DAY_OF_MONTHjava.util.Calendar.MONTH等等...

Must be one of: java.util.Calendar.DAY_OF_MONTHjava.util.Calendar.MONTH etc...

我不明白这个错误，因为Calendar.MONTH是java.util.calendar.MONTH之一

I don't understand this error because Calendar.MONTH is one of java.util.calendar.MONTH

我有一个导入它

import java.util.Calendar;

对不起，我错过了，它的初始化，但存在这样的情况我想用Calendar.MONTH和其他类等这样的：

Sorry I missed that it's initialized but there is an other class where I want to use Calendar.MONTH and so on like this:

mCalendarToday = Calendar.getInstance();

...

int dayOfWeek = mCalendar.get(Calendar.DAY_OF_WEEK);
int firstDay = getDay(mCalendar.get(Calendar.DAY_OF_WEEK);

或

private Calendar mCalendarToday;

...

private boolean isToday(int day, int month, int year) {
    if (mCalendarToday.get(Calendar.MONTH) == month
        && mCalendarToday.get(Calendar.YEAR) == year
        && mCalendarToday.get(Calendar.DAY_OF_MONTH) == day) {
        return true;
    }
    return false;
}

下面显示的错误了。和所有其他行，我会用。 感谢和问候

Here shows error too. And all the other lines where I would use. Thanks and regards
