eu tenho umAppBar e um layout linear horizontal (que inclui um texto de edição e dois botões de imagem) e outras coisas no meu layout. Quando o usuário rola para baixo,eu queroAppBar(na verdade, oToolbar esconder. Isto é o que eu tentei, a barra de aplicativos não está escondendo, apenas permanece lá. Eu segui oChris Banes Cheesesquare Sample.

Aqui está a captura de tela do meu aplicativo:

Quando o usuário rola, eu quero queAppBar/Toolbar desaparecer, e esse layout horizontal, que inclui o edittext, substitui a barra de aplicativos e fica lá.

Você pode me dizer o que estou fazendo de errado?
