Mediastyle通知在android 11中不起作用

implementation 'androidx.media:media:1.4.1'

// 创建通知渠道
NotificationChannel channel = new NotificationChannel("channel_id", "Channel Name", NotificationManager.IMPORTANCE_DEFAULT);
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);

// 创建通知构建器
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "channel_id")
        .setSmallIcon(R.drawable.notification_icon)
        .setContentTitle("Notification Title")
        .setContentText("Notification Content");

// 设置MediaStyleCompat样式
MediaStyleCompat mediaStyle = new MediaStyleCompat.Builder()
        .setMediaSession(MediaSessionCompat.Token.fromToken(mediaSession.getSessionToken()))
        .setShowActionsInCompactView(0, 1, 2) // 设置在紧凑视图中显示的操作按钮
        .setShowCancelButton(true) // 显示取消按钮
        .setCancelButtonIntent(cancelIntent) // 设置取消按钮的意图
        .build();

builder.setStyle(mediaStyle);

// 发送通知
NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(this);
notificationManagerCompat.notify(notificationId, builder.build());
