解决方法
无论何时在NotificationCompat.WearableExtender中使用addAction(),您实际上并没有扩展操作(尽管名称),而是将它们分成两个列表,一个用于电话,另一个用于可穿戴设备.
>手持设备上显示原始NotificationCompat.Builder上添加的操作.
> WearableExtender上添加的操作显示在Android Wear设备上.
见Specifying Wearable-only Actions：
If you want the actions available on the wearable to be different from
those on the handheld,then useWearableExtender.addAction(). Once you
add an action with this method,the wearable does not display any
other actions added withNotificationCompat.Builder.addAction(). That
is,only the actions added withWearableExtender.addAction()appear on
the wearable and they do not appear on the handheld.
因此,要创建仅限手持设备的操作,请在创建扩展程序之前添加它们.要进行仅可穿戴动作,请在扩展器上添加它们.如果您使用扩展器并且想要在两个设备中重复操作,则必须在两者中添加它们(尽管可能有复制它们的选项？).
例如：
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("The title")
.setContentText("This is the text")
.setContentIntent(pendingIntent);
// Handheld-only actions.
notificationBuilder.addAction(drawable1,"In Both",pendingIntent);
notificationBuilder.addAction(drawable2,"Only in phone",pendingIntent);
// Wearable-only actions.
NotificationCompat.WearableExtender wearableExtender = new NotificationCompat.WearableExtender();
wearableExtender.addAction(new NotificationCompat.Action.Builder(drawable2,pendingIntent).build());
wearableExtender.addAction(new NotificationCompat.Action.Builder(drawable3,"Only in wearable",pendingIntent).build());
notificationBuilder.extend(wearableExtender);
// Build and show notification.
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(notificationId,notificationBuilder.build());
也
>如果您创建了WearableExtender但未向其中添加任何操作,则使用原始通知中的操作.>手持设备的“内容意图”似乎总是出现在手表上,带有“打开电话”文本.我还没有找到一种方法只为手表禁用此功能.
