禁用通知的振动 [英] Disable vibration for a notification

问题描述

我正在使用通知编写应用程序.Google 开发者指南鼓励开发者提供自定义通知的设置(禁用振动、设置通知声音...)，因此如果用户这样设置，我会尝试禁用通知的振动.

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.

我正在使用 NotificationCompat.Builder 来创建通知，如下所示:

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);

我尝试了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);`

我还尝试在结果对象上构建通知和更改值:

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

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

但是出现通知时手机还是会震动.

But the phone still vibrates when the notification appears.

如何禁用通知的振动?

推荐答案

经过长时间的试用 &错误会话，我想我终于明白出了什么问题.

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

问题出在这个指令notificationBuilder.setDefaults(Notification.DEFAULT_ALL).

无论您在设置 DEFAULT_ALL 或 DEFAULT_VIBRATE 后传递给 notificationBuilder.setVibrate() 什么参数，都将被静默丢弃.谷歌的某个人一定决定给予 setDefaults 比 setVibrate 更高的优先级.

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.

这就是我最终在我的应用中禁用通知振动的方式:

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

这是可行的，但是为了禁用振动而初始化一个新的 long[] 感觉不对.

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