NAY. You need to make a request to retrieve the ad, which is only possible through a class. See an example:
// fazendo uma requisição
AdRequest adRequest = new AdRequest.Builder().build();
// adicionando a requisição no AdView.
adView.loadAd(adRequest);
See more details in the Adrequest documentation.
Paiva, try not to insert image of your code, but the code itself here. This makes it much easier!
