Magento 2: Change Store View in Admin Product List

I think the best answer to this question currently looks like this (using price as example attribute):

/** @var  \Magento\Catalog\Model\ProductFactory */
protected $productFactory;

/** @var  \Magento\Catalog\Model\ResourceModel\Product */
protected $productResourceModel;

public function __construct(
    \Magento\Catalog\Model\ProductFactory $productFactory,
    \Magento\Catalog\Model\ResourceModel\Product $productResourceModel
)
{
    $this->productFactory = $productFactory;
    $this->productResourceModel = $productResourceModel;
}


private function setStoreViewPrice($productId, $storeId, $price)
{
    $product = $this->productFactory->create();
    $this->productResourceModel->load($product, $productId);
    $product->setStoreId($storeId);
    $product->setPrice($price);
    $this->productResourceModel->saveAttribute($product, 'price');
}

What you have to understand is the baseUrl is the same even you have multiple store views. the value that changes is for example : StoreId, StoreCode, storeName etc...

If you want to get the baseUrl, it will be the same in all stores :

$storeManager->getStore()->getBaseUrl() //domaine.com

if you want to get the currentUrl, it will be different in each store :

$storeManager->getStore()->getCurrentUrl() //domaine.com/?___store=default___from_store=pro
$storeManager->getStore()->getCurrentUrl($storeManager->getStore()->getId()) //domaine.com/?___store=default___from_store=2

If you want to set à specific store view, you append at the url ?___store=storeviewcode :

domaine.com/?___store=pro
