이 기사에서는 RXJAVA RETROFIT 구현 구현 쇼핑 카트 디스플레이에 대한 특정 코드를 공유합니다. 특정 내용은 다음과 같습니다
모든 사람에게 먼저 렌더링을 보여줍니다
프레임 워크 구조 :
1. 프로젝트 프레임 워크 : MVP, 이미지 로딩은 Fresco에 의해 수행되며 Okhttp+Retrofit (직접 캡슐화, 싱글 톤 모드 추가)를 사용하여 네트워크 요청이 구현됩니다.
2. 쇼핑 카트 데이터 추가 완료 (인터페이스에 데이터가 없으면 인터페이스 도구를 사용하여 데이터를 추가 할 수 있음).
3. 뷰를 사용자 정의하여 추가 및 뺄셈 버튼을 구현하십시오. 추가 및 빼기를 클릭 할 때마다 품목의 총 수와 총 가격은 그에 따라 변경되어야합니다.
4. 수량이 1이면 마이너스 부호를 클릭하면 수량이 변경되지 않은 상태로 유지되며 토스트는 최소 수가 1이라고 사용자에게 프롬프트합니다.
5. 맨 아래의 총 수와 총 가격은 모든 품목 품목의 총 가격과 총 수입니다. 각 품목의 수량 가격이 변경되면 하단의 총 가격의 총 수를 연결해야합니다.
6. 단일 선택 리버스 선택 ALL의 기능을 구현하고, 기본 선택을 처음으로 입력하십시오. 항목을 선택하지 않은 경우 총 수와 총 가격이 하단 데이터에 포함되지 않습니다. 선택한 상태가 변경되면 바닥의 총 수와 총 가격을 올바르게 수정할 수 있습니다.
7. 삭제 버튼을 클릭하여 항목을 삭제합니다. 하단의 총 수와 총 가격을 올바르게 수정할 수 있으며 인터페이스 데이터가 삭제됩니다.
필요한 종속성 및 네트워킹 권한을 추가하십시오
