Eu sou um novato tão urso comigo. Eu tenho um layout com vários botões e, em seguida, uma adview na parte inferior. Quando o anúncio é carregado, ele empurra os botões para cima e os torna muito pequenos. Existe alguma maneira de impedir que o conteúdo seja empurrado para cima?

Aqui está meu código
