Android:通知声音禁用

Question

我收到了这段代码的通知:

Notification notifica = new Notification();
notifica.flags |= Notification.FLAG_AUTO_CANCEL;
notifica.icon = R.drawable.serie_notification;
notifica.when = System.currentTimeMillis();

with notifica.defaults = notifica.defaults | Notification.DEFAULT_SOUND; 我启用默认声音,但如果我想禁用声音,我该怎么办？

Answer 1

嗯,通过这样做,它对我有用:

myNotification.defaults = 0;

尝试一下=)

Answer 2

NotificationCompat.Builder 方法

setSilent(true)

Answer 3

有可能这样做基本上只启用Notification.defaults除声音之外的所有其他声音(即Notification.DEFAULT_SOUND).

这是一个适合您的示例:

myNotification.defaults = 0;
myNotification.defaults |= Notification.DEFAULT_VIBRATE;

以下是您可以选择的所有可用选项:

Notification.DEFAULT_LIGHTS
Notification.DEFAULT_VIBRATE
Notification.DEFAULT_SOUND
Notification.DEFAULT_ALL // This enables all above 3

更新

通知.defaults已弃用

在Oreo之前的设备，Oreo及更高版本的设备上显示无声的通知

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    Intent intent = new Intent(this, AlertDetails.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); 
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);

    String CHANNEL_ID = "channel_id";

    // You must create the channel to show the notification on Android 8.0 and higher versions
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        // Set importance to IMPORTANCE_LOW to mute notification sound on Android 8.0 and above
        NotificationChannel channel = new NotificationChannel(CHANNEL_ID, "name", NotificationManager.IMPORTANCE_LOW);
        notificationManager.createNotificationChannel(channel);
    }

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, CHANNEL_ID)
            .setSmallIcon(R.drawable.notification_icon)
            .setContentTitle("My notification")
            .setContentText("Hello World!")
            // You must set the priority to support Android 7.1 and lower
            .setPriority(NotificationCompat.PRIORITY_LOW) // Set priority to PRIORITY_LOW to mute notification sound 
            .setContentIntent(pendingIntent)
            .setAutoCancel(true); 

    notificationManager.notify(
                    1001, // notification id
                    mBuilder.build());

在较新版本的 Android 中，您必须将通知通道的优先级设置为低：

var channel = new NotificationChannel(notificationChannelName, "channel", NotificationManager.IMPORTANCE_LOW);
