我正在为一个 Android 广播应用程序构建媒体风格的通知。以下是我的通知代码:
NotificationCompat.Action action = new android.support.v4.app.NotificationCompat.Action.Builder(imgNotificationAction, "playPause", pendingIntent).build();
//create new notification
NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setShowWhen(false)
.setStyle(new NotificationCompat.MediaStyle()
.setMediaSession(mediaSession.getSessionToken())
.setShowActionsInCompactView(0, 1, 2))
.setColor(ContextCompat.getColor(this, R.color.colorPrimary))
//.setLargeIcon(largeIcon)
.setSmallIcon(android.R.drawable.stat_sys_headset)
.setContentText(radioName)
.setContentTitle("Igala Radio presents")
.setContentInfo("Igala language radio")
.setContentIntent(pendingIntent)
.addAction(action);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(NOTIFICATION_ID, notificationBuilder.build());
但我在日志中收到以下异常:

我想知道为什么它会显示动作 1 超出范围(最大值 0)。这是否意味着我不能在其中添加任何动作?
.setShowActionsInCompactView(0)
代替.setShowActionsInCompactView(0, 1, 2)
