无法在Android 8中禁用通知振动

Question

我在显示通知时尝试禁用振动.

FUNC:

public static Notification buildNotifForUploaderService(Context ctx, String title, String message) {

        Notification notification;
        NotificationCompat.Builder notificationBuilder;

        //If device is Android 8+
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel notificationChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
            //setting pattern to disable vibrating
            notificationChannel.setVibrationPattern(new long[]{0L});
            notificationBuilder = new NotificationCompat.Builder(ctx, CHANNEL_ID);
        } else {
            notificationBuilder = new NotificationCompat.Builder(ctx);
            notificationBuilder.setVibrate(new long[]{0L});
        }


        notificationBuilder
                .setContentTitle(title)
                .setContentText(message)
                .setLargeIcon(BitmapFactory.decodeResource(ctx.getResources(), R.mipmap.ic_launcher))
                .setSmallIcon(R.drawable.ic_backup_black_24dp);


        notification = notificationBuilder.build();

        return notification;
    }

我在一个活动的onCreate()上调用它,如下所示:

Notification notification = NotificationHelper.buildNotifForUploaderService(this, "title", "message");
    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(1, notification);

它还在振动.我在Android 8设备上测试.我也试过了

 notificationChannel.setVibrationPattern(null);

仍然没有用.

我有

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

无论我如何定义振动模式,如:

new long[]{1000L, 500L, 300L, 1000L};

振动与我的设置不符.Onyl默认发生"两短"振动.

如果可以,请提供帮助,提前谢谢.

编辑:

正如Avijit Karmakar所说,我补充道

  notificationChannel.enableVibration(false);

完整代码:

public class MainActivity extends AppCompatActivity {

    final static String CHANNEL_ID = "MY_CHANNEL_ID";
    final static String CHANNEL_NAME = "MY_CHANNEL_NAME";


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Notification notification;
    NotificationCompat.Builder mBuilder;
    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);


    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel notificationChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
        //Disabling vibration!
        notificationChannel.enableVibration(false);
        notificationManager.createNotificationChannel(notificationChannel);
        mBuilder = new NotificationCompat.Builder(this, CHANNEL_ID);

    } else {
        mBuilder = new NotificationCompat.Builder(this);
        mBuilder.setVibrate(new long[]{0L});
    }

    mBuilder.setContentTitle("title")
            .setContentText("message")
            .setSmallIcon(R.drawable.ic_android_black_24dp);

    Bitmap bm = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
    mBuilder.setLargeIcon(bm);

    notification = mBuilder.build();
    notificationManager.notify(1, notification);
    }
}

它还在振动.

我在小米米A1(Android 8.0)上测试

任何人都可以尝试这个代码并帮助我获得结果吗？

Answer 1

使用NotificationManager.IMPORTANCE_LOW作为重要性值。

NotificationChannel notificationChannel = new NotificationChannel(
    CHANNEL_ID,
    CHANNEL_NAME,
    NotificationManager.IMPORTANCE_LOW
);

Answer 2

喜欢这个答案,做:

mNotificationChannel.setVibrationPattern(new long[]{ 0 }); 
mNotificationChannel.enableVibration(true);

重要事项1:即使我设置了上面的振动模式,但将enableVibration设置为false,它也会振动.所以,将enableVibration设置为true!

重要2:像另一个答案一样,频道会保留其初始设置,因此请再次卸载并安装应用以应用更改!

希望能帮助到你!

Answer 3

将此行添加到您的代码中以停止振动：

notificationChannel.enableVibration(false);
// Above line will disable your vibration for the notification

另外，删除振动模式。

因此，您更新的代码将是：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    NotificationChannel notificationChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
    //setting pattern to disable vibrating
    notificationChannel.enableVibration(false);

    notificationBuilder = new NotificationCompat.Builder(ctx, CHANNEL_ID);
} else {
    notificationBuilder = new NotificationCompat.Builder(ctx);
    notificationBuilder.setVibrate(new long[]{0L});
}
