我收到了此代码的通知:
Notification notifica = new Notification();
notifica.flags |= Notification.FLAG_AUTO_CANCEL;
notifica.icon = R.drawable.serie_notification;
notifica.when = System.currentTimeMillis();
notifica.defaults = notifica.defaults | Notification.DEFAULT_SOUND; 我启用默认声音,但如果我想禁用声音该怎么办?

嗯,这样做对我有用:
myNotification.defaults = 0;
试试看=)

基本上可以启用除声音(Notification.defaults
)之外的所有其他Notification.DEFAULT_SOUND
。
以下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
<强>更新强>
通知.defaults

要在Oreo之前的设备,Oreo及更高版本的设备上显示没有声音的通知
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());

在较新的Android版本中,您必须将通知渠道的优先级设置为低:
var channel = new NotificationChannel(notificationChannelName, "channel", NotificationManager.IMPORTANCE_LOW);

android“ O”> =,禁用或启用通知声音,您将两个ID用于通知通道。 一个用于发出通知,另一个在您要禁用时设置
@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);
}
