Question

我使用MediaStyle进行推送通知，以便我可以显示当前播放的歌曲元数据以及包含暂停按钮。我看到的问题是我的通知不会自动展开以显示暂停按钮，即使我已经包含了setShowActionsInCompactView（）。如果我在锁定屏幕上下拉通知，它会展开，然后显示暂停按钮。但我希望它能显示按钮而不会扩展。

在向下拉展开后如何显示通知的屏幕截图： http://cl.ly/image/1N1i0G121i2Y

以下是我用于生成通知的代码段：

        PendingIntent pi = PendingIntent.getActivity(getApplicationContext(), 0, new Intent(getApplicationContext(), MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);
        Bitmap icon = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
        Intent intent = new Intent(BROADCAST_PLAYER_STOP);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

        NotificationCompat.Builder notification = new NotificationCompat.Builder(this)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setContentTitle(getResources().getString(R.string.app_name))
                .setTicker(tickerString)
                .setContentText(contentString)
                .setSmallIcon(R.drawable.ic_notification)
                .setLargeIcon(icon)
                .addAction(R.drawable.ic_media_pause, "", pendingIntent)
                .setContentIntent(pi)
                .setStyle(new android.support.v7.app.NotificationCompat.MediaStyle()
                        .setShowActionsInCompactView(0)
                        .setMediaSession(mSession.getSessionToken()))
                .setPriority(NotificationCompat.PRIORITY_MAX)
                .setWhen(0)
                .setOngoing(true);
        startForeground(NOTIFICATION_ID, notification.build());

要使用NotificationCompat.MediaStyle，您必须使用android.support.v7.app.NotificationCompat.Builder - 默认的v4 Builder无法处理v7 MediaStyle
