Answer 1

There are lots of changes, need to your Payment method class.

1. Need to redirect to a Magento Custom Page.
2. Then From this Custom page submit a form which will hit payment gateways.
3. After Payment done/failure .paygate redirect to you a page

For 1st step1, you need do below change

add

 public function getCheckoutRedirectUrl()
 {
 return $this->_urlBuilder->getUrl('[RouteName]/[Controller]/[Action]');
 }

Your model class should be like this:

<?php
namespace Xyz\Abc\Model;
/* add by Amit Bera*/
use Magento\Sales\Api\Data\OrderPaymentInterface;
use Magento\Sales\Model\Order\Payment;
use Magento\Sales\Model\Order\Payment\Transaction;
use Magento\Quote\Model\Quote;
use Magento\Store\Model\ScopeInterface;
use Magento\Framework\Pricing\PriceCurrencyInterface;
/**
 * Bank Transfer payment method model
 *
 * @method \Magento\Quote\Api\Data\PaymentMethodExtensionInterface getExtensionAttributes()
 */
class XyzPaymentMethod extends \Magento\Payment\Model\Method\AbstractMethod
{
 const PAYMENT_METHOD_XYZ_CODE = 'xyzpaymentmethod';
 /**
 * Payment method code
 *
 * @var string
 */
 protected $_code = self::PAYMENT_METHOD_XYZ_CODE;

 protected $_canCapture = true;
 /**

 protected $_canCapturePartial = true;
 /**

 protected $_canRefund = true;
 /**

 protected $_canRefundInvoicePartial = true;
 /**

 protected $_canVoid = true;
 /**

 protected $_canUseInternal = false;
 /**

 protected $_canUseCheckout = true;
 /**

 protected $_canFetchTransactionInfo = true;
 /**

 protected $_canReviewPayment = true;

 protected $_storeManager;
 /**

 protected $_urlBuilder;

 */
 public function __construct(

 \Magento\Framework\Registry $registry,
 \Magento\Framework\Api\ExtensionAttributesFactory $extensionFactory,

 parent::__construct(

 $scopeConfig,

 $resource,
 $resourceCollection,
 $data
 );
 $this->_storeManager = $storeManager;
 $this->_urlBuilder = $urlBuilder;
 $this->_checkoutSession = $checkoutSession;
 $this->_exception = $exception; 
 }
 public function getInstructions()
 {
 return trim($this->getConfigData('instructions'));
 }
 public function getCheckoutRedirectUrl()
 {
 return $this->_urlBuilder->getUrl('[RouteName]/[Controller]/[Action]');
 }
}

Step2

For create url you need a custom url which is need contoller file

For this follow inchoo block

http://inchoo.net/magento-2/how-to-create-a-basic-module-in-magento-2/

On this file at execute().. you can get curren placed order by below code

$LastorderObject=$this->_objectManager->get('Magento\Checkout\Model\Session');
 if (!$LastorderObject-> getLastRealOrder()->getId()) {
 return $this->resultRedirectFactory->create()->setPath('checkout/cart');
 }

then render block class with phtm file .. on phmtl submit form in hidden process nad redirect to payment gateway

Answer 2

In order to build payment module with redirect you have to use Payment Gateway API presented in the Magento/Payment module. First of all you have to remove usage of AbsractMethod class usage due to a fact that this class is deprecated and no longer supported. In the upcoming releases it likely to be removed.

There is Magento/Payment/Model/Method/Adapter class exist as a new Facade when configuring payment method. With this class you can create custom Builders for different payment requests e.g. Cancel payment, Refund payment, Recurring payment and Initialization of a payment during redirect.

This class however, is a starting point for redirect implementation. Please read my answer in the Payment gateway with redirects in Magento 2 where I explain steps of creating redirect to a payment provider

Please also read about Payment Gateway Configuration to configure Magento/Payment/Model/Method/Adapter class via di.xml file for your custom payment module.

Hope it helps.
