我试图管理一组推送通知。
1. 我的第一个问题是只有最后设置的通知才能收到我的智能手机。我相信它没有创建新实例，但它覆盖了唯一的实例。我该如何解决？
2. 我的第二个问题是我希望从应用程序中，用户可以删除确定通知的时间表。
这是我在MovieAdapter.java 中的代码(主要方法是getNotification、scheduleNotification 和deleteNotification):

最佳答案
改变这一行
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
到
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, notificationIntent, PendingIntent.FLAG_ONE_SHOT); //Here 0 is the intent requestcode.
Make sure intent request code is unique in order to differentiate intents.
