如果和廣播接收器

Question

在BroadcastReceiver類中，我有這段代碼，但我不明白為什么第一次通知不運行。 如果我刪除周期，則Alarmmanager可以完美運行。 值也可以（我舉杯向我展示）。 是“如果”問題嗎？

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);
    }
    }

您應該用else完成if的操作。 如果您擊中else則記錄錯誤

還要檢查if的所有條件，例如notify和CheckBoxPreference的值是什么。 這應該可以幫助您自己調試代碼。

   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

    }
