안녕하세요! 1주차 과제 수행하시느라 고생 많으셨습니다💚
작성해주신 코드에 대한 리뷰를 정리했으니 참고하시면 좋을 것 같습니다.

총평

ViewBinding을 활용해 전반적으로 코드가 깔끔하고, 감정 선택도 단일 선택 UX로 잘 구현하셨습니다.

1. ConstraintLayout (배치 방식)

activity_main.xml은 각 뷰를 이전 요소의 bottom ↔ 다음 요소의 top으로 연결해서 위에서 아래로 내려오는 연속 배치 구조로 잘 작성되어 있습니다.
다만 화면 높이가 작은 기기에서는 감정 우표 영역이 아래에서 잘릴 수 있는(overflow) 가능성이 있어, 추후에는 NestedScrollView 적용 등도 한 번 고려해보면 좋겠습니다.

2. Chain

현재 XML에는 app:layout_constraintVertical_chainStyle 같은 설정이 없어서, 뷰들이 체인으로 묶여 있지는 않습니다.
Chain은 여러 뷰를 한 묶음으로 연결해 간격/정렬(spread, packed 등) 을 조절하는 기능이라, 나중에 화면 크기 대응이나 간격을 더 깔끔하게 정리하고 싶을 때 참고하면 좋습니다.

3. Kotlin 코드

selectEmotion()에서 전체 텍스트 색을 먼저 초기화한 뒤 선택한 텍스트만 색을 바꾸는 방식이라 선택이 누적되지 않고 단일 선택이 잘 동작합니다. 👍

(선택 개선)
아이콘뿐 아니라 텍스트도 클릭 가능하게 하면 터치 UX가 더 좋아질 수 있고, 색상 값은 추후 colors.xml로 분리하면 관리가 더 편해질 수 있습니다.

추가로 ViewBinding을 사용했다면 buildFeatures { viewBinding true }가 Gradle에 켜져 있는지도 함께 확인해 주세요!

코드 리뷰 확인해보시고 궁금한 점 있으면 언제든지 말씀해주세요!
