Android 通知时的振动和声音默认值

我试图在收到通知时获得默认的振动和声音警报，但到目前为止运气不佳。我想这与我设置默认值的方式有关，但我不确定如何修复它。有什么想法吗

public void connectedNotify() {
    Integer mId = 0;
    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_notify)
            .setContentTitle("Device Connected")
            .setContentText("Click to monitor");

    Intent resultIntent = new Intent(this, MainActivity.class);

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    stackBuilder.addParentStack(MainActivity.class);
    stackBuilder.addNextIntent(resultIntent);
    PendingIntent resultPendingIntent =     
          PendingIntent.getActivity(getApplicationContext(), 
          0, 
          resultIntent,  
          PendingIntent.FLAG_UPDATE_CURRENT);
    mBuilder.setContentIntent(resultPendingIntent);
    mBuilder.setOngoing(true);
    Notification note = mBuilder.build();
    note.defaults |= Notification.DEFAULT_VIBRATE;
    note.defaults |= Notification.DEFAULT_SOUND;
    NotificationManager mNotificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(mId, note);

}

一些伪代码可能会对您有所帮助

   private static NotificationCompat.Builder buildNotificationCommon(Context _context, .....) {
            NotificationCompat.Builder builder = new NotificationCompat.Builder(_context)
            .setWhen(System.currentTimeMillis()).......;
     //Vibration
        builder.setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 });

     //LED
        builder.setLights(Color.RED, 3000, 3000);

     //Ton
        builder.setSound(Uri.parse("uri://sadfasdfasdf.mp3"));

    return builder;
   }

在

AndroidManifest.xml

文件中添加以下振动权限

<uses-permission android:name="android.permission.VIBRATE" />

这对我来说很好，你可以试试

 protected void displayNotification() {

        Log.i("Start", "notification");

      // Invoking the default notification service //
        NotificationCompat.Builder  mBuilder =
                new NotificationCompat.Builder(this);
        mBuilder.setAutoCancel(true);

        mBuilder.setContentTitle("New Message");
        mBuilder.setContentText("You have "+unMber_unRead_sms +" new message.");
        mBuilder.setTicker("New message from PayMe..");
        mBuilder.setSmallIcon(R.drawable.icon2);

      // Increase notification number every time a new notification arrives //
        mBuilder.setNumber(unMber_unRead_sms);

      // Creates an explicit intent for an Activity in your app //

        Intent resultIntent = new Intent(this, FreesmsLog.class);

        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        stackBuilder.addParentStack(FreesmsLog.class);

      // Adds the Intent that starts the Activity to the top of the stack //
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                        0,
                        PendingIntent.FLAG_UPDATE_CURRENT
                );
        mBuilder.setContentIntent(resultPendingIntent);

      //  mBuilder.setOngoing(true);
        Notification note = mBuilder.build();
        note.defaults |= Notification.DEFAULT_VIBRATE;
        note.defaults |= Notification.DEFAULT_SOUND;

        mNotificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
      // notificationID allows you to update the notification later on. //
        mNotificationManager.notify(notificationID, mBuilder.build());

    }

TeeTracker答案的延伸

要获取默认通知声音，可以执行以下操作

NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_notify)
            .setContentTitle("Device Connected")
            .setContentText("Click to monitor");

Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
builder.setSound(alarmSound);

---

这将为您提供默认通知声音。

通知 振动

mBuilder.setVibrate(new long[] { 1000, 1000});

声音

mBuilder.setSound(Settings.System.DEFAULT_NOTIFICATION_URI);

我正在使用下面的代码，它对我来说工作正常

private void sendNotification(String msg) {
    Log.d(TAG, "Preparing to send notification...: " + msg);
    mNotificationManager = (NotificationManager) this
            .getSystemService(Context.NOTIFICATION_SERVICE);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, MainActivity.class), 0);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
            this).setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("GCM Notification")
            .setAutoCancel(true)
            .setDefaults(Notification.DEFAULT_ALL)
            .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
            .setContentText(msg);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    Log.d(TAG, "Notification sent successfully.");
}

这是一种通过使用系统中的默认振动和声音来调用通知的简单方法

private void sendNotification(String message, String tick, String title, boolean sound, boolean vibrate, int iconID) {
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);
    Notification notification = new Notification();

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);

    if (sound) {
        notification.defaults |= Notification.DEFAULT_SOUND;
    }

    if (vibrate) {
        notification.defaults |= Notification.DEFAULT_VIBRATE;
    }

    notificationBuilder.setDefaults(notification.defaults);
    notificationBuilder.setSmallIcon(iconID)
            .setContentTitle(title)
            .setContentText(message)
            .setAutoCancel(true)
            .setTicker(tick)
            .setContentIntent(pendingIntent);

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

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

如果要使用振动权限，请添加振动权限：

<uses-permission android:name="android.permission.VIBRATE"/>

祝你好运。

对于科特林，你可以试试这个

var builder=NotificationCompat.builder（此，通道ID）
.SetVibration（longArrayOf（1000、1000、1000、1000、1000））
.setSound（Settings.System.DEFAULT\u通知\u URI）

//设置通知音频

builder.setDefaults(Notification.DEFAULT_VIBRATE);
//OR 
builder.setDefaults(Notification.DEFAULT_SOUND);

为了支持SDK版本>=26，您还应该构建NotificationChanel并在那里设置振动模式和声音。有一个Kotlin代码示例：

    val vibrationPattern = longArrayOf(500)
    val soundUri = "<your sound uri>"

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val notificationManager =    
                 getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
            val attr = AudioAttributes.Builder()
                        .setUsage(AudioAttributes.USAGE_ALARM)
                        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                        .build()
            val channelName: CharSequence = Constants.NOTIFICATION_CHANNEL_NAME
            val importance = NotificationManager.IMPORTANCE_HIGH
            val notificationChannel =
                NotificationChannel(Constants.NOTIFICATION_CHANNEL_ID, channelName, importance)
                notificationChannel.enableLights(true)
                notificationChannel.lightColor = Color.RED
                notificationChannel.enableVibration(true)
                notificationChannel.setSound(soundUri, attr)
                notificationChannel.vibrationPattern = vibrationPattern
                notificationManager.createNotificationChannel(notificationChannel)
    }

权限在某些情况下，您应该使用十六进制颜色argb格式，如0xffffffff，而不是color.White，因为用户设备使用颜色（RGB）的可能性很小对于ARGB参数，您将得到错误的颜色。这发生在我身上。振动现在有1000毫秒的延迟。如果你将第一个设置为0，它会立即消失。这是一种{延迟，振动，睡眠，振动，睡眠}模式。我不需要添加

来工作。有人知道如何在API 26上使用setSound吗？所有的答案都只是重复了你已经拥有的代码的一些变体，在我看来，没有一个能回答这个问题。你的代码看起来很好，AFAICT。最有可能的是，您只是缺少AndroidManifest.xml中的android.permission.vibration。对于可能在此线程中应用解决方案但在通知上仍然没有任何振动的用户，您可能需要首先启用通知通道的振动。看看这个：对于振动一个，确保在您的AndroidManifest.xml中包含

，这个振动持续多长时间？或者它只会振动一次？有人能告诉我为什么手机在通话时振动不起作用吗？或者我们可以发出强制振动的通知，即使在电话中也是这样吗@用户526206，我不知道。我从来没有测试过。您可以打开新问题，因为这与通知行为无关。
