How to Add Clear Shopping Cart Button in Magento 2

system->configuration->sales section ->checkout->shopping cart->After Adding a Product Redirect to Shopping Cart=no

mage->checkout->controllers->cartcontroller-> you need to work on addAction method (you can directly give $url=home url or product list url.and you need to override cartcontroller).

if (!$this->_getSession()->getNoCartRedirect(true)) {
                if (!$cart->getQuote()->getHasError()) {
                    $message = $this->__('%s was added to your shopping cart.', Mage::helper('core')->escapeHtml($product->getName()));
                    $this->_getSession()->addSuccess($message);
                }
                $this->_goBack();
            }

........... ....

$url = $this->_getSession()->getRedirectUrl(true);
            if ($url) {
                $this->getResponse()->setRedirect($url);
            } else {
                $this->_redirectReferer(Mage::helper('checkout/cart')->getCartUrl());
            }

I have completed by using this code and working perfect.

Find below code from file - template\checkout\cart\item\default.phtml

<input type="text" pattern="\d*" name="cart[<?php echo $_item->getId() ?>][qty]" value="<?php echo $this->getQty() ?>" size="4" data-cart-item-id="<?php echo $this->jsQuoteEscape($_item->getSku()) ?>" title="<?php echo Mage::helper('core')->quoteEscape($this->__('Qty')) ?>" class="input-text qty" maxlength="12" />

Replace it with below code

<a class="decrement_qty_<?php echo $_item->getId(); ?>" href="javascript:void(0)">-</a> 
<input type="text" pattern="\d*" name="cart[<?php echo $_item->getId() ?>][qty]" value="<?php echo $this->getQty() ?>" size="4" data-cart-item-id="<?php echo $this->jsQuoteEscape($_item->getSku()) ?>" title="<?php echo Mage::helper('core')->quoteEscape($this->__('Qty')) ?>" class="input-text qty" maxlength="12" />
<a class="increment_qty_<?php echo $_item->getId(); ?>" href="javascript:void(0)">+</a>

Add below code to end of file

<script type="text/javascript">
    //<![CDATA[

    jQuery(document).ready(function(){
        var itemId = '<?php echo $_item->getId(); ?>';
        jQuery('.increment_qty_'+itemId).click(function() {
            jQuery('.btn-update').css('display','block');
            var oldVal = jQuery(this).parent().find("input").val();
            if ( parseFloat(oldVal) >= 1 ) {
                var newVal = parseFloat(oldVal) + 1;
                jQuery(this).parent().find("input").val(newVal);
            }
        });

        jQuery('.decrement_qty_'+itemId).click(function() {
            jQuery('.btn-update').css('display','block');
            var oldVal = jQuery(this).parent().find("input").val();
            if ( parseFloat(oldVal) >= 2 ) {
                var newVal = parseFloat(oldVal) - 1;
                jQuery(this).parent().find("input").val(newVal);
            }
        });
    });
    //]]>
</script>
