我尝试在显示通知时禁用振动。

功能:

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;
    }

我这样在 Activity 的 onCreate() 上调用它:

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

它仍在振动。我在 Android 8 设备上进行测试。 我也试过了

 notificationChannel.setVibrationPattern(null);

还是不行。

我有

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

无论我如何定义振动模式，例如:

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

振动不符合我的设置。 Onyl默认发生“两短”振动。

如果可以请帮忙，在此先感谢。

编辑:

正如 Avijit Karmakar 提到的，我已经添加了

  notificationChannel.enableVibration(false);

完整代码现在:

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 Mi A1 (Android 8.0) 上测试

任何人都可以尝试这段代码并帮助我得到结果吗？

最佳答案

像这样answer , 做:

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

重要 1:即使我在上面设置了振动模式，但将 enableVibration 设置为 false，它也会振动。因此，将 enableVibration 设置为 true!

重要2:像这样another answer ， channel 会保留其初始设置，因此卸载并再次安装该应用程序以应用更改!

希望对您有所帮助!
