BottomAppBar

fabAlignmentMode 오목함을 만들 위치를 지정합니다.
전용 center/end레이아웃 추기앙코르를 사용하면 오목함을 잘 준다는 평을 받아 수정했다.app:layout_anchor="@+id/bottomappbar"

Chip/ChipGroup

Choice3을 선택한 상태에서 초기화된 샘플app:singleSelection="true" 이것은 어느 것을 선택된 상태로 만들었는가

MaterialCardView

CardView와 비교하면 어떻게 달라졌습니까?
stroke Color/Stroke Width가 추가되었습니까?
※ 다시 한 번

MaterialButton

<android.support.design.button.MaterialButton
        android:layout_width="wrap_content"
        android:layout_height="60dp"
        android:gravity="center_vertical"
        android:text="MaterialButton"
        android:textColor="#FFFFFF"
        app:cornerRadius="16dp"
        app:icon="@drawable/ic_android_black_24dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        />  

다음 두 가지를 지정할 수 있는 것은

cornerRadius

icon

rippleColor를 지목할 수도 있지만 아무래도 잘 안되는 것 같아서 다음에 얘기하자

한마디

대충 해본 거니까 잘못된 점이나 원래 새로운 곳이 아니라는 지적이 있으면 알려주세요.
안드로이드-P의 총결산도 며칠 앞으로 다가온다.
