禁用振动的通知 [英] Disable vibration for a notification

问题描述

我使用的通知写一个应用程序。谷歌开发的指导方针鼓励开发者提供程序设置自定义通知（禁用振动，设置通知的声音... ...），所以我试图禁用振动通知，如果用户设置这种方式。

I'm writing an app using notification. Google developer guidelines encourages developers to provide settings to customize the notifications (disable vibration, set notification sound...), so I am trying to disable vibration for notifications if the user set it that way.

我使用 NotificationCompat.Builder 以创建通知，像这样的：

I am using NotificationCompat.Builder to create the notification, like this:

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(Application.getContext())
            .setDefaults(Notification.DEFAULT_ALL)
            .setPriority(Notification.PRIORITY_MAX)
            .setSmallIcon(R.drawable.ic_launcher)
            .setLargeIcon(largeIconBitmap)
            .setAutoCancel(true)
            .setContentIntent(resultPendingIntent)
            .setContentTitle(title)
            .setContentText(content);

我尝试不同的方法来禁用通知：

I tried different ways to disable notifications:

notificationBuilder.setVibrate(null);

notificationBuilder.setVibrate(new long[]{0l, 0l});

notificationBuilder.setDefaults(Notification.DEFAULT_ALL | ~Notification.DEFAULT_VIBRATE);

notificationBuilder.setDefaults(Notification.DEFAULT_LIGHTS | Notification.DEFAULT_SOUND);`

我也试图建立通知和变化值所产生的对象：

I also tried to build the notification and change values on the resulting object:

Notification notification = notificationBuilder.build();
notification.vibrate = null;

但出现在通知时手机仍然振动。

But the phone still vibrates when the notification appears.

我如何禁用振动通知？

推荐答案

一个长期的试验和功放后，错误会议，我想我终于明白了什么是错的。

After a long trial & error session, I think I finally understood what's wrong.

问题就出在这个指令 notificationBuilder.setDefaults（Notification.DEFAULT_ALL）。

无论你通过什么样的参数设置后， notificationBuilder.setVibrate（） DEFAULT_ALL 或 DEFAULT_VIBRATE 将被丢弃。有人在谷歌必须决定给予较高的precedence到使用setdefaults 比 setVibrate 。

No matter what parameter you pass to notificationBuilder.setVibrate() after setting DEFAULT_ALL or DEFAULT_VIBRATE will be silently discarded. Someone at Google must have decided to give a higher precedence to setDefaults than to setVibrate.

这就是我结束了禁用的振动在我的应用程序的通知：

This is how I ended up disabling vibration for notifications in my app:

notificationBuilder.setDefaults(Notification.DEFAULT_LIGHT | Notification.DEFAULT_SOUND)
                   .setVibrate(new long[]{0l}); // Passing null here silently fails

这个作品，但感觉不对初始化一个新的长[] 只是为了禁止震动。

This works but doesn't feel right to initialize a new long[] just to disable the vibration.
