如何在浮动动作按钮中将图像设置为居中裁剪

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentEnd="true"
        android:layout_margin="16dp"
        app:srcCompat="@drawable/ic_add"
        app:layout_anchor="@id/fab_container"
        app:layout_anchorGravity="bottom|end" />

    <ImageView
        android:id="@+id/image_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"
        android:src="@drawable/your_image" />

</RelativeLayout>

FloatingActionButton fab = findViewById(R.id.fab);
ImageView imageView = findViewById(R.id.image_view);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
