Question

我是否可以从一个方案(服务)中提出不止一份情况通知,或者我应该以可点击的物体清单(例如)制定新的活动?

你肯定能够发出一份以上的服务或申请通知,但你必须要求,作为用户,你希望申请向您发出垃圾邮件通知。我先在我的边远处使用一份通知,并仅更新其内容,重新使用同一通知。例如:

public void onPlaybackStarted(int currentTrack, Show show) {
notificationManager.cancel(R.layout.notification_playing);

notification.tickerText = show.getTracks().get(currentTrack).getName();
if (notificationView == null) {
    notificationView = new RemoteViews(getPackageName(), R.layout.notification_playing);
}
notificationView.setTextViewText(R.id.notification_playing_track, show.getTracks().get(currentTrack).getName());
notificationView.setTextViewText(R.id.notification_playing_band, show.getArtist());
notificationView.setTextViewText(R.id.notification_playing_date, show.getDate());
Intent intent = new Intent(TrackPlayerService.this, ListTracksActivity.class)
        .putExtra("track", currentTrack)
        .putExtra("artist", show.getArtist())
        .putExtra("date", show.getDate())
        .putExtra("location", show.getLocation())
        .putExtra("venue", show.getVenue())
        .addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
notification.contentView = notificationView;
notification.contentIntent = PendingIntent.getActivity(TrackPlayerService.this, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
notification.flags |= Notification.FLAG_ONGOING_EVENT;

notificationManager.notify(R.layout.notification_playing, notification);
}

如果您的通知不是循环的,即你需要同时向用户通报3或4件不同的事项,那么发出开放清单的通知是最好的出路。
