Eu tenho uma visão de reciclador (A) contendo outra visão de reciclagem (B). Quando clico no ícone de adição no item de reciclagem (A), ele abre uma nova atividade com uma reciclagem (C). Pressionar e selecionar alguns itens e clicar em Concluído. Isso precisa atualizar um item de reciclagem (B) no item de reciclagem (A) no qual eu cliquei no ícone de adição.

Mas, em vez disso, todos os itens da revisão de reciclagem (A) que contêm a revisão de reciclagem (B) estão sendo atualizados.
