Eu fiz um programa semelhante. Espero que isso ajude você. Em sua primeira atividade, quatro dados de grade podem ser selecionados. Na próxima atividade, há um pager de exibição que contém duas páginas obrigatórias e mais quatro páginas estarão lá, que serão visíveis correspondentes aos dados da grade selecionados.
A seguir, é apresentada a principal atividade MainActivity

Aqui TabFragment1, TabFragment2 etc são fragmentos a serem exibidos no viewpager. E não estou mostrando os layouts, pois estão fora do escopo deste projeto.
