從服務發送多個意圖到接收者

我正在做一個簡單的應用程序，在一天中的8個不同時間生成通知。服務正在使用警報管理器生成警報，我正在使用廣播接收器來捕捉警報並顯示敬酒/創建通知。從服務發送多個意圖到接收者

問題是我無法創建多個警報。我用來創建多個警報的方法是他們每個人的不同意圖..但是一旦我在模擬器上啓動應用程序，所有的消息能在單一時間同時顯示.. 我不知道這是否是正確的方法.. 如果是，請幫我糾正如果沒有，請建議我一些替代方法

附上我的代碼服務和接收器

是任何人那裏？ – Yashasvi

我想這種情況正在發生，因爲你正在使用FLAG_UPDATE_CURRENT標誌

pendingi1 = PendingIntent.getBroadcast(this, 0, i1,PendingIntent.FLAG_UPDATE_CURRENT);

使用FLAG_ONE_SHOT無處不在，如果你不想被取代了以往的PendingIntent。

pendingi1 = PendingIntent.getBroadcast(this, 0, i1,PendingIntent.FLAG_ONE_SHOT);

不，它不工作只要我從另一個活動開始服務，所有的敬酒立刻出現。 – Yashasvi

我看到你的硬編碼時間到了下午4:40，設備上的時間還不止於此？ – nandeesh

實際上，每當我運行應用程序，我確保所有的時間值都超過了模擬器時間 – Yashasvi

我認爲這正在發生的事情，因爲你正在使用相同的通知ID爲所有的重疊所以用不同的ID所有這nm.notify（0，通知）; 取代0到1,2,3 ...
