当我在应用程序中使用FCM推送通知时，每当通知在状态栏中显示最新的通知时，我都希望显示所有通知，直到用户单击为止。如果我使用挂起的intent。Flag_current表示它在android中显示最新的通知请帮助我。

注意：我想向用户显示所有通知，当他们单击通知时，它应该显示，否则我想显示所有通知。请帮助我。基于通知，只有清除旧通知，用户才需要执行任务意味着，用户不知道以前发出了什么通知。
答案 0 :(得分：0)
您应为每个通知使用不同的notifyId，以将其单独显示。 Add a new notification when push notification receives (not replace old one)
在这里已经有答案在发布新问题之前，请先搜索SO。
答案 1 :(得分：0)
您具有通知int notifyID = 1所使用的硬编码ID； 因此，每次收到通知时，都会将相同的值（1）传递给方法
mNotificationManager.notify(notifyID , notification);
使其覆盖上一个，确保每次显示通知时都传递唯一的“ notifyID”，例如，我建议将int notifyID设置为静态并在将通知增量值显示为1以后，或者可以使用时间戳记（时间戳很长，因此将其类型转换为int），然后传入方法。
希望这会有所帮助，
快乐的编码...：）
