但是，通知收件箱样式会在收到通知时更新

Question

我正在尝试制作一种通知样式，我希望所有通知都集中在一个引擎盖下，并且它们将逐行显示。如果有新通知，它应该在第二晚。通知列表应该是 5 个，这意味着只能显示最新的 5 个。

我正在使用下面的代码，我不知道如何实现这一点，我也尝试了 StackBuilder，但是我知道了，这可以通过比我现在使用的更高的 API 工作。

NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
Intent notificationIntent = new Intent(this, GcmActivity.class);
notificationIntent.putExtra("title", messagetype);
notificationIntent.putExtra("message", msg);
PendingIntent intent = PendingIntent.getActivity(this, 0,notificationIntent, 0);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
        | Intent.FLAG_ACTIVITY_SINGLE_TOP);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this).setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle("MY MESSENGER").setContentText("MESSAGES");
NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
inboxStyle.setBigContentTitle("MESSAGES" + " Details");

    inboxStyle.addLine(messagetype + ":" + msg);


mBuilder.setStyle(inboxStyle);
mBuilder.setContentIntent(intent);
mBuilder.setAutoCancel(true);
notificationManager.notify(Integer.parseInt("0"), mBuilder.build());

我知道我可以通过在创建时添加任意数量的行来做到这一点

NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();  

但是我希望当我的 GCMIntentService 被调用时，这个列表会被更新。

我也尝试使用下面的代码进行这项工作，但是也没有用

 NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
Intent notificationIntent = new Intent(this, GcmActivity.class);
notificationIntent.putExtra("title", messagetype);
notificationIntent.putExtra("message", msg);
PendingIntent intent = PendingIntent.getActivity(this, 0,notificationIntent, 0);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
        | Intent.FLAG_ACTIVITY_SINGLE_TOP);



NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(  
        this).setAutoCancel(true)  
        .setContentTitle("MY MESSENGER")  
        .setSmallIcon(R.drawable.ic_launcher)
        .setContentText("MESSAGES");  

 NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();  

for(int j= 0; j<listMessage.size(); j++)
  inboxStyle.addLine(listMessage.get(j));  
mBuilder.setStyle(inboxStyle);
mBuilder.setContentIntent(intent);
notificationManager.notify(0, mBuilder.build());

我遇到了同样的问题，并通过将通知持久化到数据库中来修复它，以便在新通知到达时加载它们，并在单击或删除时将其删除。

DatabaseHelper dbHelper = new DatabaseHelper(this);
    Cursor notifications = dbHelper.getAllNotifications();
    NotificationCompat.Builder mBuilder = extractNotifications(title, msg, contentIntent, notifications);
    dbHelper.insertNotification(title + ": " + msg);

private NotificationCompat.Builder extractNotifications(String title, String msg, PendingIntent contentIntent, Cursor notifications) {
    NotificationCompat.Builder mBuilder;
        mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.ic_icon)
                        .setContentTitle(title)
                        .setStyle(new NotificationCompat.BigTextStyle()
                                .bigText(NOTIFICAITONS))
                        .setContentText(msg)
                        .setAutoCancel(true)
                        .setLights(Color.WHITE, 1000, 5000)
                        .setDefaults(Notification.DEFAULT_VIBRATE |
                                Notification.DEFAULT_SOUND | Notification.DEFAULT_LIGHTS)
                        .setContentIntent(contentIntent);

        NotificationCompat.InboxStyle inboxStyle =
                new NotificationCompat.InboxStyle();

        inboxStyle.setBigContentTitle(NOTIFICAITONS);
        while (notifications.moveToNext())
        {
            inboxStyle.addLine(notifications.getString(notifications.getColumnIndex(DatabaseHelper.NOTIFICATION_MESSAGE)));
        }
        inboxStyle.addLine(title + ": " + msg);
        mBuilder.setStyle(inboxStyle);
    return mBuilder;

您需要自己执行此操作，通过将自己的 ID 分配给您的通知，您将能够稍后对其进行更新。您还需要自己构建通知，通过连接消息
