在NotificationCompat.Builder的RemoteViews（自定义布局）中单击按钮时显示/隐藏视图

Question

我正在进行FCM通知，因为我无法继续进行，因此我遇到了一个奇怪的问题。

以上是我创建的自定义通知。我需要显示/隐藏相应于“接受”或“拒绝”按钮单击的底部灰色视图。

我只能在使用下面的代码

单击“接受”或“拒绝”按钮时创建待定意图

    // Using RemoteViews to bind custom layouts into Notification
    RemoteViews remoteViews = new RemoteViews(getPackageName(),
            R.layout.custom_notifications);

  // reject button click intent
    Intent rejectIntent = new Intent(this, MainActivity.class);
    PendingIntent rejectIntentPending = PendingIntent.getActivity(this, 0, rejectIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    // approve button click intent
    Intent approveIntent = new Intent(this, SubActivity.class);
    PendingIntent acceptIntentPending = PendingIntent.getActivity(this, 0, approveIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);

   NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            // Set Icon
            .setSmallIcon(R.drawable.logo)
            // Set Ticker Message
            .setTicker("notification received")
            // Dismiss Notification
            .setAutoCancel(true)
            //.setWhen(0)
            // Set PendingIntent into Notification
            .setContentIntent(pIntent)
            // Set RemoteViews into Notification
            // .setContent(remoteViews)
            // Set Title
            .setContentTitle("App Name")
            // show big notification hint when app is open
            //.setPriority(Notification.PRIORITY_MAX)
            // Set Text
            .setContentText(messageBody)
            // Set Sound
            .setSound(defaultSoundUri)
            // notification button 2
            .addAction(rejectAction)
            // notification button 3
            .addAction(approveAction)
            // Set RemoteViews into Notification
            .setContent(remoteViews);

但是如何处理View。任何帮助对我都有很大的帮助。

这是可能的情景......
