如果和广播接收器

Question

在BroadcastReceiver类中，我有这段代码，但我不明白为什么第一次通知不运行。 如果我删除周期，则Alarmmanager可以完美运行。 值也可以（我举杯向我展示）。 是“如果”问题吗？

CheckboxPreference = prefs.getBoolean("checkboxPref", true);
    notify = prefs.getString("notify", "");

if (CheckboxPreference){
        if (notify.equals("1")){
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, morningAlarm);
        }
        if (notify.equals("2")){
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, morningAlarm);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal3.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, eveningAlarm);
        }
        if (notify.equals("3")){
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, morningAlarm);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal2.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, middleAlarm);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal3.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, eveningAlarm);
    }
    }

您应该用else完成if的操作。 如果您击中else则记录错误

还要检查if的所有条件，例如notify和CheckBoxPreference的值是什么。 这应该可以帮助您自己调试代码。

   if (CheckboxPreference){
        if (notify.equals("1")){
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, morningAlarm);
        }

        else if (notify.equals("2")){
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, morningAlarm);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal3.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, eveningAlarm);
        }
        else if (notify.equals("3")){
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, morningAlarm);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal2.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, middleAlarm);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal3.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, eveningAlarm);
        }
        else {
           // Log something
        }
    }  
    else {
       // Log CheckBoxPref false

    }
