無法添加浮動操作按鈕-無法膨脹

Question

我已經研究了其余的答案，但是它們似乎都建議更新依賴項等。但是，我正在為SDK 28開發，所有內容都是最新的，並且已經通過Android Studio進行了檢查，因此似乎另一個原因。

基本上，我通過XML添加了一個浮動操作按鈕：

<android.support.design.widget.FloatingActionButton
    android:id="@+id/dict_fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="end|bottom"
    android:src="@drawable/ic_add_circle_black_24dp"
    android:layout_margin="16dp" />

當我嘗試加載包含FAB的活動時，遇到以下崩潰。

將implementation 'com.android.support:design:27.1.0'添加到所有其他依賴項所在的app / build.gradle中。
