Best Answer

  1. You need to confirm that, you create test.phtml file at this location.
    Vendor\Modulename\view\adminhtml\templates\test.phtml

  2. You need to replace _prepareLayout function code like this.

    <?php
namespace Vendor\Modulename\Block\Adminhtml\Customerids\Edit\Tab;

use Magento\Backend\Block\Template\Context;
use Magento\Framework\Registry;

class Meat extends \Magento\Backend\Block\Template
{

  protected function _prepareLayout()
  {
      $customhtml = parent::_prepareLayout();
      $customhtml .= $this->setTemplate('Vendor_Modulename::test.phtml')->toHtml();
      return $customhtml;
  }
}
