Magento layout file not called? – Magento Cloud Hosting

This is my Controller Index.php

<?php

namespace HikmadhMenuControllerAdminhtmlProduct;

class Index extends MagentoFrameworkAppActionAction
{
/** @var MagentoFrameworkViewResultPageFactory  */
protected $resultPageFactory;
public function __construct(
     MagentoFrameworkAppActionContext $context,
     MagentoFrameworkViewResultPageFactory $resultPageFactory
) {
     $this->resultPageFactory = $resultPageFactory;
     parent::__construct($context);
}
/**
* Load the page defined in view/adminhtml/layout/samplenewpage_sampleform_index.xml
*
* @return MagentoFrameworkViewResultPage
*/
public function execute()
{
     $resultPage = $this->resultPageFactory->create();
     $resultPage->getConfig()->getTitle()->prepend(__('Add Products'));
     return $resultPage;
}
}
