代码没有报错，设置好闹铃时间之后延迟将近50秒才有反应~请问这是什么回事？我把我代码贴出来，希望大神们能指导一下~~

Calendar c = Calendar.getInstance();
c.setTimeInMillis(System.currentTimeMillis());
//根据用户选择的时间来设置Calendar对象
c.set(Calendar.HOUR, hourOfDay);
c.set(Calendar.MINUTE, minute);
//设置AlarmManager将在Calender对应的时间启动指定组件
aManager.set(AlarmManager.RTC, c.getTimeInMillis(), pi);

}
}, currentTime.get(Calendar.HOUR_OF_DAY), currentTime.get(Calendar.MINUTE),false).show();

------解决思路----------------------
aManager.set(AlarmManager.RTC,c.getTimeInMillis(), pi);
你输出下这个getTimeInMillis，貌似是时区问题

你没发现时间不对么……你的截图是星期2 11：30分？现在才刚星期二吧
