Layout1의 모양을 카드뷰 모양으로 바꾸기

카드뷰는 프로필과 같은 간단 정보를 넣기 위해 각 영역을 구분하는 역할을 한다

    <androidx.cardview.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:cardBackgroundColor="#FFFFFFFF"
        app:cardCornerRadius="10dp"
        app:cardElevation="5dp"
        app:cardUseCompatPadding="true">

 

cardCornerRadius - 모서리 둥글게 설정

cardElevation - 뷰가 올라온 느낌이 들게 함

cardUseCompatPadding - 기본 패딩 적용
