关于AlarmManager闹钟提醒的功能，
本人现在在正做一个日程提醒的功能。现在有一个AgendasActivity，该Activity显示的是数据库里查询出来的日程任务，其中有日程的开始时间。
现在我要做的是设置一个闹钟提醒功能。就是时间到了日程的开始时间后，自动打开AgendasActivity。
现在假设有3条日程。
日程1：开始时间是 2012-06-07 08：00：00
日程2：开始时间是 2012-06-07 09：00：00
日程3：开始时间是 2012-06-07 10：00：00
要求就是时间分别到达这3个时间点，闹钟都会响，而且自动打开AgendasActivity。该怎么实现。
看了网上都是用alarmmanager.set方法，现在的问题是alarmmanager.set()方法写在哪个Activity中？是AgendasActivity还是重新新建一个Activity？
我现在自己做的是把他放在Broadcast中的，但是时间到点后不起作用.
public class BootReceive extends BroadcastReceiver{
private static final String SQL = "MPBT_DailySchedule 4, '" ;
private static final String[] PARAMS = new String[]{"ID","EmployeeID","Subject","Site",
"BeginDate","BeginTime",
"EndTime","RatingID", "StateName",
"ReminderID", "RemindStyleID","Content",
"Result","CreatorID","CreatedDate","State"};
private ArrayList<HashMap<String, Object>> datelist;
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
//设置闹钟提醒功能
//得到AlarmManager管理权限
AlarmManager alarm = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
//AlarmManager要做的事情,打开Activity
//创建PendingIntent,将intent 添加到里面
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, new Intent(context, AgendasActivity.class), PendingIntent.FLAG_ONE_SHOT);
//根据设置的提醒方式，对闹钟进行设定提醒
/** RemindStyleID:
* 0提前0分

datelist = AgendasDBUtil.select(SQL + "430" + "'", PARAMS);
System.out.println(datelist);
Calendar RemindTime = Calendar.getInstance();//获取当前时间
SimpleDateFormat dft = new SimpleDateFormat("yyyy-MM-dd HH:mm:00");
for(int i=0;i<datelist.size();i++){
if(datelist.get(i).get("RemindStyleID").toString().equals("0")){
try {
RemindTime.setTime(dft.parse(datelist.get(i).get("BeginDate").toString() + " " + datelist.get(i).get("BeginTime").toString()));
alarm.set(AlarmManager.RTC_WAKEUP, RemindTime.getTimeInMillis(), pendingIntent);
