推荐答案

您必须跟踪计数.您可以扩展Application类:

You have to keep track of the count. You could extend the Application class:

public class AppName extends Application {
    private static int pendingNotificationsCount = 0;

    @Override
    public void onCreate() {
        super.onCreate();
    }

    public static int getPendingNotificationsCount() {
        return pendingNotificationsCount;
    }

    public static void setPendingNotificationsCount(int pendingNotifications) {
        pendingNotificationsCount = pendingNotifications;
    }
}

您应该修改onReceive:

And you should modify the onReceive:

@Override
public void onReceive(Context context, Intent intent) {
    ...
    int pendingNotificationsCount = AppName.getPendingNotificationsCount() + 1;
    AppName.setPendingNotificationsCount(pendingNotificationsCount);
    notification.number = pendingNotificationsCount;
    ...
}

您可以在用户打开通知时重置计数:

And you could reset the count when the user open the notification:

AppName.setPendingNotificationsCount(0);
