日历

• 设置闹钟提醒

  在Android 4.4 以后，为节省电池耗电等，不再使用一个重复闹钟，而是使用多个单次闹钟，当前一个闹钟到点提醒以后，再次设置下一个闹钟。

获取日历的当前时间

public Date getStartTime(String startTime){
     Date startDate = DateUtil.tFormat8(startTime);
     Calendar calendar=Calendar.getInstance();
     calendar.setTime(startDate);
     Date nowDate = DateUtil.nowDate(BaseApplication.getContext());
     Calendar nowCalendar = Calendar.getInstance();
     nowCalendar.setTime(nowDate);
     calendar.set(Calendar.YEAR, nowCalendar.get(Calendar.YEAR));
     calendar.set(Calendar.MONTH, nowCalendar.get(Calendar.MONTH));
     calendar.set(Calendar.DAY_OF_MONTH, nowCalendar.get(Calendar.DAY_OF_MONTH));
     return calendar.getTime();
}

####判断某个日期的所属的星座
public class ConstellationUtil{
private final static int[] dayArr = new int[]{20, 19, 21, 20, 21, 22, 23, 23, 23, 24, 23, 22};
private final static String[] constellationArr = new String[]{ “摩羯座”, “水瓶座”, “双鱼座”, “白羊座”, “金牛座”, “双子座”, “巨蟹座”, “狮子座”, “处女座”, “天秤座”, “天蝎座”, “射手座”, “摩羯座”};

    public static String getConstellation(int month, int day){
        return day < dayArr[month - 1] ? constellationArr[month - 1] : constellationArr[month];
    }

    public static getConstellation(Date date){
        if(date == null)
            return "";
        Calendar canlendar = Calendar.getInstance();
        canlendar.setTime(date);
        int month = canlendar.get(Calendar.MONTH) + 1;
        int day = canlendar.get(Calendar.DAY_OF_MONTH);

        return getConstellation(month, day);
    }
}
