Question

此表单的开发是在同一页面上发送数据。

我想在发送和显示消息时隐藏联系表单，例如：感谢您与我们联系。

我提出的问题是，当您执行发送操作时，表单会被隐藏并显示错误消息，但联系表单仍然是隐藏的。

更新您的代码：

//I am using write now this can possible    
  NotificationManager notificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(icon, message, when);

        Intent notificationIntent = new Intent(context, HomeActivity.class);

        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                | Intent.FLAG_ACTIVITY_SINGLE_TOP);

        PendingIntent intent = PendingIntent.getActivity(context, 0,
                notificationIntent, 0);

        notification.setLatestEventInfo(context, title, message, intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notificationManager.notify(0, notification);
