android - Android、Java - setSmallIcon() 隐藏在新通知中。但通知仍然存在于通知抽屉中

问题描述

我真的迷路了。是否存在隐藏状态栏中的通知图标但通知仍存在于抽屉中的情况？在回复现有通知后将传入消息附加到通知时会发生这种情况。

我用 ：

NotificationCompat.MessagingStyle.extractMessagingStyleFromNotification();

一切正常，但通知图标隐藏。我也用

NotificationManager.IMPORTANCE_HIGH

这是通知生成器代码。

   NotificationCompat.MessagingStyle activeNotification = NotificationCompat.MessagingStyle.extractMessagingStyleFromNotification();
  
                    return new NotificationCompat.Builder(getApplicationContext(), ID)
                            .setContentIntent(pIntent)
                           .addAction(action)
                            .setSmallIcon( R.drawable.icon)
                            .setAutoCancel(true)
                              .setSound(uri)
                             .setStyle(activeNotification
                                    .addMessage(body, SystemClock.currentThreadTimeMillis(), person)
                              )
                            ;

提前致谢。

解决方案

您可以按照下面的通知生成器。我正在设置这样的小图标：

val notificationBuilder: NotificationCompat.Builder =
        NotificationCompat.Builder(context, channelId)

notificationBuilder.setSmallIcon(R.mipmap.ic_launcher_round)

更新：

我正在发布我的完整代码以显示通知。

val pendingIntent =
        PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT)

    val notificationBuilder: NotificationCompat.Builder =
        NotificationCompat.Builder(context, channelId)

    notificationBuilder.setSmallIcon(R.mipmap.ic_launcher_round)
    notificationBuilder.color = 0x474E54

    notificationBuilder.setContentTitle(title)
        .setContentText(message)
        .setAutoCancel(false)
        .setStyle(NotificationCompat.BigTextStyle())
        .setSound(Settings.System.DEFAULT_NOTIFICATION_URI)
        .setContentIntent(pendingIntent)
        .setDefaults(Notification.DEFAULT_ALL)
        .setAutoCancel(true)
        .setCategory(NotificationCompat.CATEGORY_SOCIAL)

    val notificationManager: NotificationManager =
        context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        val importance = NotificationManager.IMPORTANCE_HIGH
        val notificationChannel = NotificationChannel(
            channelId,
            channelId,
            importance
        )

        notificationChannel.enableLights(true)
        notificationChannel.lightColor = Color.RED
        notificationChannel.enableVibration(true)
        notificationChannel.vibrationPattern = longArrayOf(0, 1000, 500, 1000)
        notificationBuilder.setChannelId(channelId)
        notificationManager.createNotificationChannel(notificationChannel)

    } else {
        notificationBuilder.priority = NotificationCompat.PRIORITY_HIGH
        notificationBuilder.setVibrate(longArrayOf(0, 1000, 500, 1000))
    }

    notificationManager.notify(notificationId, notificationBuilder.build())

您可以根据需要更改它。希望这会有所帮助。:)
