Add a breadcrumb to a view page?
You should create a custom module (use core >= 8.3). Use this code as a base to start:

custom_breadcrumb.info.yml

name: 'Custom breadcrumbs'
description: 'Custom breadcrumbs implementation'
package: 'Custom'
# core: 8.x
type: module

version: '8.x-1.0'
core: '8.x'
project: 'custom_breadcrumb'
datestamp: 1443649740


custom_breadcrumb.services.yml

services:
  custom_breadcrumb.breadcrumb_views:
    class: Drupal\custom_breadcrumb\Breadcrumb\ViewsBreadcrumbBuilder
    tags:
      - { name: breadcrumb_builder, priority: 1 }


src/Breadcrumb/ViewsBreadcrumbBuilder.php

&lt;?php

namespace Drupal\custom_breadcrumb\Breadcrumb;

use Drupal\Core\Breadcrumb\BreadcrumbBuilderInterface;
use Drupal\Core\Routing\RouteMatchInterface;
use Drupal\Core\Routing\LinkGeneratorTrait;
use Drupal\Core\StringTranslation\StringTranslationTrait;
use Drupal\Core\Link;

class ViewsBreadcrumbBuilder implements BreadcrumbBuilderInterface {
  use LinkGeneratorTrait;
  use StringTranslationTrait;

  /**
   * @inheritdoc
   */
  public function applies(RouteMatchInterface $route_match) {
    // This breadcrumb apply only for some views.
    $parameters = $route_match-&gt;getParameters()-&gt;all();

    if (isset($parameters['view_id'])) {

       $views_id = array(
         'VIEW_MACHINE_NAME_1',
         'VIEW_MACHINE_NAME_2',
       );

       if (in_array($parameters['view_id'], $views_id)) {
         return TRUE;
       }
       return FALSE;
    }
  }

  /**
   * @inheritdoc
   */
  public function build(RouteMatchInterface $route_match) {
    // Breadcrumbs set up (cache settings are so important!).
    $breadcrumb = new \Drupal\Core\Breadcrumb\Breadcrumb();
    $breadcrumb-&gt;addCacheContexts(["url"]);
    $breadcrumb-&gt;addCacheTags(["view_id:{$parameters['view_id']}"]);

    $parameters = $route_match-&gt;getParameters()-&gt;all();
    if (isset($parameters['view_id'])) {
      if ($parameters['view_id'] == 'VIEW_MACHINE_NAME_1') {
         $breadcrumb-&gt;addLink(Link::createFromRoute(t('VIEWS NAME 1'), '&lt;none&gt;'));
      }
      else if ($parameters['view_id'] == 'VIEW_MACHINE_NAME_2') {
        $breadcrumb-&gt;addLink(Link::createFromRoute(t('VIEWS NAME 2'), '&lt;none&gt;'));
      } 
    }

    // Reverse order for this to work!!!.
    $breadcrumb-&gt;addLink(Link::createFromRoute($this-&gt;t('Home'), '&lt;front&gt;'));
    return $breadcrumb;
  }
}


Remember to replace VIEW_MACHINE_NAME_1 and VIEW_MACHINE_NAME_2 with the machine name of your views. Also replace VIEWS NAME 1 and VIEWS NAME 2 with the breadcrumb title you want for each view.
