<?xml version="1.0" encoding="UTF-8"?>
<listing xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <listingToolbar name="listing_top">
            <massaction name="listing_massaction">
                <action name="mass_order_assigntrackingnumber">
                    <argument name="data" xsi:type="array">
                        <item name="config" xsi:type="array">
                            <item name="type" xsi:type="string">order_assigntrackingnumber</item>
                            <item name="label" xsi:type="string" translate="true">Assign Tracking Number</item>
                            <item name="url" xsi:type="url" path="helloworld/orderprocessing/"/>
                        </item>
                    </argument>
                </action>
            </massaction>
    </listingToolbar>
</listing>

Mass Action Controller

Update code by this:

<?php
namespace Inchoo\Helloworld\Controller\Adminhtml\Orderprocessing;
class Index extends \Magento\Sales\Controller\Adminhtml\Order\AbstractMassAction {

    protected function massAction(AbstractCollection $collection){
        //your code here
        //Here you will get collection
    }
}
