虽然有一个类似的问题，但它并没有给我一个解决方案。当我尝试使用com.google.android.material.floatingactionbutton.FloatingActionButton它时运行良好。但是如果我尝试使用com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton，它会出错。

我在 XML 文件中的代码：

<com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
    android:id="@+id/book_profile_write_review"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="20dp"
    android:contentDescription="@string/author_name"
    android:text="@string/book_name"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintStart_toStartOf="parent"
    app:srcCompat="@drawable/ic_launcher_foreground" />
