Magento 2 Get All Payment Methods

There are two methods to get all payment methods in Magento 2

Method 1: Use Dependency Injection

To use this method paste the following code into the block class.

/**
* Order Payment
*
* @var \Magento\Sales\Model\ResourceModel\Order\Payment\Collection
*/
protected $_orderPayment;

/**
* Payment Helper Data
*
* @var \Magento\Payment\Helper\Data
*/
protected $_paymentHelper;

/**
* Payment Model Config
*
* @var \Magento\Payment\Model\Config
*/
protected $_paymentConfig;

/**
* @param \Magento\Backend\Block\Template\Context $context
* @param \Magento\Sales\Model\ResourceModel\Order\Payment\Collection $orderPayment
* @param \Magento\Payment\Helper\Data $paymentHelper
* @param \Magento\Payment\Model\Config $paymentConfig
* @param array $data
*/
public function __construct(
\Magento\Backend\Block\Template\Context $context,
\Magento\Sales\Model\ResourceModel\Order\Payment\Collection $orderPayment,
\Magento\Payment\Helper\Data $paymentHelper,
\Magento\Payment\Model\Config $paymentConfig,
array $data = []
) {
$this->_orderPayment = $orderPayment;
$this->_paymentHelper = $paymentHelper;
$this->_paymentConfig = $paymentConfig;
parent::__construct($context, $data);
}

/**
* Get all payment methods
* 
* @return array
*/ 
public function getAllPaymentMethods() 
{
return $this->_paymentHelper->getPaymentMethods();
}

/**
* Get key-value pair of all payment methods
* key = method code & value = method name
* 
* @return array
*/ 
public function getAllPaymentMethodsList() 
{
return $this->_paymentHelper->getPaymentMethodList();
}

/**
* Get active/enabled payment methods
* 
* @return array
*/ 
public function getActivePaymentMethods() 
{
return $this->_paymentConfig->getActiveMethods();
}

/**
* Get payment methods that have been used for orders
* 
* @return array
*/ 
public function getUsedPaymentMethods() 
{
$collection = $this->_orderPayment;
$collection->getSelect()->group('method');
$paymentMethods[] = array('value' => '', 'label' => 'Any');
foreach ($collection as $col) { 
$paymentMethods[] = array('value' => $col->getMethod(), 'label' => $col->getAdditionalInformation()['method_title']); 
} 
return $paymentMethods;
}

Method 2: Use Object Manager

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 

$paymentHelper = $objectManager->get('Magento\Payment\Helper\Data');
$allPaymentMethods = $paymentHelper->getPaymentMethods();
$allPaymentMethodsArray = $paymentHelper->getPaymentMethodList();

var_dump($allPaymentMethodsArray);
var_dump($allPaymentMethods);

$paymentConfig = $objectManager->get('Magento\Payment\Model\Config');
$activePaymentMethods = $paymentConfig->getActiveMethods();

var_dump(array_keys($activePaymentMethods));

$orderPaymentCollection = $objectManager->get('\Magento\Sales\Model\ResourceModel\Order\Payment\Collection');
$orderPaymentCollection->getSelect()->group('method');
$paymentMethods[] = array('value' => '', 'label' => 'Any');
foreach ($orderPaymentCollection as $col) { 
$paymentMethods[] = array('value' => $col->getMethod(), 'label' => $col->getAdditionalInformation()['method_title']); 
}
