過去的通知顯示當前通知

Question

我正在使用AlarmManager來重複報警。我爲週一，週四和週六設置了重複鬧鐘。鬧鈴在週一正確顯示，但週四到來時，它會一起顯示兩個通知，並在週六顯示全部三個通知。我該如何對其進行編碼，以便在第一次報警完成時，它不會在同一周的隨後報警中顯示，而是會在接下來的幾周內顯示？

} 

就是這樣，在主要活動中，您將看到四個單獨的日曆變量，我必須創建一個Receiver，Receiver1，Receiver2，Receiver3和AlarmService1,2,3。對於每個日曆，不是最好的方式，但只有我能想到的東西。我添加了：

Date now = new Date(System.currentTimeMillis()); 
if (calendar3.getTime().before(now)) { 
    calendar3.add(Calendar.MONTH, 1); 
} else if (calendar.getTime().before(now)) { 
    calendar.add(Calendar.HOUR, 168); 
} else if (calendar1.getTime().before(now)) { 
    calendar1.add(Calendar.HOUR, 168); 
} else if (calendar2.getTime().before(now)) { 
    calendar2.add(Calendar.HOUR, 168); 
} 

我今天添加了日期部分，沒有檢查出來知道它是否會工作。感謝您幫助我！

Alaram Service如何工作？

它根據您的條件開始，就像您爲日，周或任何一週設置的一樣。所以在每個指定的時間設置它接收命令。像通知，語氣。

so onStartServiceCommand（）方法。你必須爲此應用邏輯。

因此，該通知僅在該特定日期發生一次。
