单个闹铃是实现了，但多个闹铃实现不了！比如我第一个闹铃的时间设置为Thur May 14 23:33:00 CST (China) 2015，第二个闹铃的时间设置为Thur May 14 23:25:00 CST (China) 2015，然后到了23：25分的时候，两个闹铃就一起响了！！！下面我把主要代码贴上来！

alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

btn.setOnClickListener(new OnClickListener() {

//假设把在数据库读取到的数据增加到数组
time.add("Thur May 14 23:47:00 CST (China) 2015");

int minute) {

c.setTimeInMillis(System.currentTimeMillis());
c.set(Calendar.HOUR_OF_DAY, hourOfDay);
c.set(Calendar.MINUTE, minute);
c.set(Calendar.SECOND, 0);
c.set(Calendar.MILLISECOND, 0);
time.add(c.getTime().toString());//把在程序界面设置的时间添加到数组
// 如果数组是空的，直接创建闹铃，否则用数组的值创建多个闹铃
if (time.isEmpty()) {
Intent intent = new Intent(MainActivity.this,
AlarmReceiver.class);
PendingIntent pi = PendingIntent.getBroadcast(
MainActivity.this, 0, intent, 0);
alarmManager.set(AlarmManager.RTC_WAKEUP,
c.getTimeInMillis(), pi); // 设置闹钟
} else {
while(i < time.size()) {
Intent intent = new Intent(MainActivity.this,
AlarmReceiver.class);
PendingIntent pi = PendingIntent
.getBroadcast(MainActivity.this, i, intent, PendingIntent.FLAG_UPDATE_CURRENT);
String dateTime = time.get(i);
Log.v("第" + i + "个时间", dateTime);
try {
c.setTime(new SimpleDateFormat(
"yyyyMMddHHmmss")
.parse(dateTime)); // 将字符串转化为毫秒
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
alarmManager.set(AlarmManager.RTC_WAKEUP,
c.getTimeInMillis(), pi); // 用把转换为毫秒后的数组的值设置闹钟
i++;
}
}
}
}, cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE),
false);
break;
}
return dialog;
}
}
------解决思路----------------------
能否debug看下，为什么两个闹铃会响，估计是逻辑有问题
