Android：通知声音禁用

Question

I have a notification with this code:

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; I enable the default sound but if I want to disable the sound how can I do??

Answer 1

Well, it worked for me by doing this:

myNotification.defaults = 0;

Try it out =)

Answer 2

To show notifications without sound on pre Oreo devices, Oreo and above devices

    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());

It is possible to do that basically just enable all of the other Notification.defaults except the sound ( which is Notification.DEFAULT_SOUND ).

Here is an example that will work for you:

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

Here are all of the available the options you can select:

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

Update

Notification .defaults deprecated

android "O" >= , Disable or Enable sound of the notification you use two ids for notification channel. one for sounded notification and another is set when you want to disable

@RequiresApi(api = Build.VERSION_CODES.O)
    private void createNotificationChannel(Context context, NotificationManager mNotificationManager, boolean playSound) {


    // The user-visible name of the channel.
    CharSequence name = context.getString(R.string.channel_name);

    // The user-visible description of the channel.

    String description = context.getString(R.string.channel_description);
    int importance = NotificationManager.IMPORTANCE_HIGH;
    NotificationChannel mChannel = new NotificationChannel(playSound ? channel_id_sound : channel_id_no_sound, name, importance);

    // Configure the notification channel.
    mChannel.setDescription(description);
    mChannel.enableLights(true);

    // Sets the notification light color for notifications posted to this
    // channel, if the device supports this feature.
    mChannel.setLightColor(Color.RED);
    mChannel.enableVibration(true);
    mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
    if (!playSound)
        mChannel.setSound(null, null);
    mNotificationManager.createNotificationChannel(mChannel);
}

Answer 5

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);

Answer 6

You can disable the sound using this

NotificationChannel channel = new NotificationChannel(CHANNEL_ID, "Channel name", NotificationManager.IMPORTANCE_LOW);
channel.setSound(null, null);

Just set the sound of channel as null

Answer 7

NotificationCompat.Builder method

setSilent(true)
