Este artigo compartilha o código específico para a exibição de carrinho de compras de implementação do RXJAVA para sua referência. O conteúdo específico é o seguinte
Mostre a todos as renderizações primeiro
Estrutura da estrutura:
1. Estrutura do projeto: MVP, o carregamento da imagem é feito pelo Fresco, solicitações de rede são implementadas usando o Okhttp+Retrofit (Encapsulate você mesmo, adicione o modo Singleton),
2. Conclua a adição de dados do carrinho de compras (se não houver dados na interface, você poderá adicionar dados usando a ferramenta de interface).
3. Personalize a exibição para implementar o botão Adição e subtração. Cada vez que você clicar em Adicionar e subtrair, o número total e o preço total do item devem ser alterados de acordo.
4. Quando a quantidade for 1, clique no sinal de menos, a quantidade permanece inalterada e a torrada leva ao usuário que o número mínimo é 1.
5. O número total e o preço total na parte inferior são o preço total e o número total em todos os itens do item. Se o preço da quantidade em cada item for alterado, o número total do preço total na parte inferior deve estar vinculado a ele.
6. Implemente a função de seleção reversa de escolha única, digite a seleção padrão pela primeira vez, o número total e o preço total não estão incluídos nos dados inferiores quando o item não estiver selecionado. Quando o estado selecionado é alterado, o número total e o preço total da parte inferior podem ser modificados corretamente.
7. Clique no botão Excluir para excluir o item. O número total e o preço total na parte inferior podem ser modificados corretamente e os dados da interface serão excluídos.
