【问题描述】：

我正在努力在我现有的应用程序中添加多个警报功能。早些时候，警报只有一个，一切正常。我已经能够设置多个警报，它也工作正常，但问题在于贪睡功能。早些时候，贪睡运行完美。但是，在多个警报实施后，它不起作用。一旦我按下贪睡按钮，我就永远不会得到关于贪睡闹钟的对话框。这是我的代码：

设置报警方式

public void setAlarm(boolean AlarmEnabled, int AlarmHour, int AlarmMin) 
        //Build Intent/Pending Intent for setting the alarm
        Intent AlarmIntent = new Intent(MultipleAlarmActivity.this, AlarmReceiver.class);
        AlarmManager AlmMgr = (AlarmManager)getSystemService(ALARM_SERVICE);
        int _id = (int)System.currentTimeMillis();
        AlarmIntent.putExtra("REQUEST CODE", _id);
        Log.v("MultipleAlarmActivity RequestCode", ""+_id);
        PendingIntent Sender = PendingIntent.getBroadcast(MultipleAlarmActivity.this, _id, AlarmIntent, 0);     

        //Build Calendar objects for setting alarm
        Calendar curCalendar = Calendar.getInstance();
        Calendar alarmCalendar = Calendar.getInstance();

        //Initialize Seconds and Milliseconds to 0 for both calendars
        curCalendar.set(Calendar.SECOND, 0);
        curCalendar.set(Calendar.MILLISECOND, 0);           
        alarmCalendar.set(Calendar.SECOND, 0);
        alarmCalendar.set(Calendar.MILLISECOND, 0);

        //Update alarmCalendar with Alarm Hour and Minute Settings
        alarmCalendar.set(Calendar.HOUR_OF_DAY, AlarmHour);
        alarmCalendar.set(Calendar.MINUTE, AlarmMin);

        //If Alarm Time is now or in the past, set it for tomorrow 24 hours in advance from time selected
        if (alarmCalendar.getTimeInMillis() <= curCalendar.getTimeInMillis()) 
            alarmCalendar.add(Calendar.HOUR, 24);
        
        //Set the alarm
        AlmMgr.set(AlarmManager.RTC_WAKEUP, alarmCalendar.getTimeInMillis(), Sender);

        //Build the Strings for displaying the alarm time through Toast
        String CalendarHourStr;
        if (AlarmHour > 12) 
            CalendarHourStr = Integer.toString(AlarmHour - 12);
         else 
            CalendarHourStr = Integer.toString(AlarmHour);
        
        String CalendarMinStr = Integer.toString(AlarmMin);
        if (AlarmMin < 10) 
            CalendarMinStr = "0" + CalendarMinStr;
        

        String strAmPM;
        if (AlarmHour < 12) 
            strAmPM = "AM";
        
        else 
            strAmPM = "PM";
        
        String alarmTime = Integer.toString(alarmCalendar.get(Calendar.MONTH) + 1) + "/" + Integer.toString(alarmCalendar.get(Calendar.DAY_OF_MONTH)) + "/" + Integer.toString(alarmCalendar.get(Calendar.YEAR)) + " " + CalendarHourStr + ":" + CalendarMinStr + " " + strAmPM;
        Toast.makeText(this, "Alarm Set For " + alarmTime, Toast.LENGTH_LONG).show();       
         Log.v("MultipleAlarmActivity setAlarm", "in if loop");
    Log.v("MultipleAlarmActivity setAlarm", "setAlarm called");
 

报警接收器

public class AlarmReceiver extends BroadcastReceiver

public static final String ALARM_ALERT_ACTION = "com.android.alarmclock.ALARM_ALERT";
public static final String ALARM_INTENT_EXTRA = "intent.extra.alarm";

@Override
public void onReceive(Context context, Intent intent) 
 
    Intent in = new Intent(Intent.ACTION_MAIN);
    in.setClass(context, SnoozeActivity.class);
    Log.v("AlarmReceiver RequestCode", ""+intent.getIntExtra("REQUEST CODE", 0));
    in.putExtra("REQUEST CODE", intent.getIntExtra("REQUEST CODE", 0));
    in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(in);

打盹闹铃的方法

private void snooze() 

        //Set Calendar Value for Snooze Alarm
        Calendar calendar = Calendar.getInstance();
        //int snoozeTime = mMinute + SNOOZE_MIN;
        calendar.add(Calendar.MINUTE, SNOOZE_MIN); //SNOOZE_MIN = 1;
        long snoozeTime = calendar.getTimeInMillis();
        //Build Intent and Pending Intent to Set Snooze Alarm               
        Intent AlarmIntent = new Intent(SnoozeActivity.this, AlarmReceiver.class);
        AlarmManager AlmMgr = (AlarmManager)getSystemService(ALARM_SERVICE);
        AlarmIntent.putExtra("REQUEST CODE", req_code);
        PendingIntent Sender = PendingIntent.getBroadcast(SnoozeActivity.this, req_code, AlarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);   
        AlmMgr.set(AlarmManager.RTC_WAKEUP, snoozeTime, Sender);
        timer.cancel();   

【参考方案1】：

我发现了问题。我使用布尔值来检查是否设置了警报。而且，我在调用 setAlarm() 时忘记将此值设置为 true。那是我的错误。
