根据出生日期算出年龄

其中加了注消的部分属于详细的年龄计算，连月份都一起计算进去了。一般不求周岁虚岁阳历阴历这种的可以使用未被注销过得部分

Calendar cal = Calendar.getInstance();

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

int age = 0;

try {

    int yearNow = cal.get(Calendar.YEAR);

    // int monthNow = cal.get(Calendar.MONTH);

    // int dayOfMonthNow = cal.get(Calendar.DAY_OF_MONTH);

    cal.setTime(sdf.parse(csrq));

    int yearBirth = cal.get(Calendar.YEAR);

    // int monthBirth = cal.get(Calendar.MONTH);

    // int dayOfMonthBirth = cal.get(Calendar.DAY_OF_MONTH);

    age = yearNow - yearBirth;

    // if (monthNow <= monthBirth) {

            // if (monthNow == monthBirth) {

                    // if (dayOfMonthNow < dayOfMonthBirth)

                    // age--;

             // } else {

                        // age--;

     // }

// }
