Answer 1

The above to seem correct, but I think that jumping straight to the Registry is not the best approach. Magento provides a Layer Resolver that already encapsulates that functionality. (See the TopMenu Block in the Catalog Plugins)
I suggest injecting the \Magento\Catalog\Model\Layer\Resolver class and using that to get the current category. Here is the code :
<?php
namespace FooBar\Demo\Block;
class Demo extends \Magento\Framework\View\Element\Template
{
private $layerResolver;
public function __construct(
\Magento\Framework\View\Element\Template\Context $context,
\Magento\Catalog\Model\Layer\Resolver $layerResolver,
array $data = []
) {
parent::__construct($context, $data);
$this->layerResolver = $layerResolver;
}
public function getCurrentCategory()
{
return $this->layerResolver->get()->getCurrentCategory();
}
}
Here is what the actual getCurrentCategory() method does in the Resolver Class.
public function getCurrentCategory()
{
$category = $this->getData('current_category');
if ($category === null) {
$category = $this->registry->registry('current_category');
if ($category) {
$this->setData('current_category', $category);
} else {
$category = $this->categoryRepository->get($this->getCurrentStore()->getRootCategoryId());
$this->setData('current_category', $category);
}
}
return $category;
}
As you can see, it does still use the registry but it provides a fallback in case that fails.

Magento sets registry for categories being accessed. So, to get currenct category, use following method:
/**
* #param \Magento\Framework\Registry $registry
*/
protected $_registry;
public function __construct(
\Magento\Framework\Registry $registry
) {
$this->_registry = $registry;
}
and then use:
$category = $this->_registry->registry('current_category');//get current category
Now you can access the collection and fetch details such as $category->getName()

Answer 3

No need to use the object manager or inject class. You can use a built-in helper class Magento\Catalog\Helper\Data in the following way.
<?php
$catalogHelperData = $this->helper('Magento\Catalog\Helper\Data');
$categoryObject = $catalogHelperData->getCategory();
$categoryId = $categoryObject->getId();
$categoryName = $categoryObject->getName();
?>
This code snippet should work for any phtml (built-in or custom) file which is related to product listing page or product detail page.

Try this code. this will definitely help you.
<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$category = $objectManager->get('Magento\Framework\Registry')->registry('current_category');//get current category
echo $category->getId();
echo $category->getName();
?>

In *.phtml files at Category page can get Category data with following snippet:
$currentCategory = $this->helper('Magento\Catalog\Helper\Data')->getCategory();
