约束布局约束尺寸比不适用于多个视图

Question

我对约束尺寸比有疑问。图像视图的宽度和高度未调整。我想根据比例使图像拇指视图正方形。我希望图像缩略图的宽度和高度等于布局中给出的三个文本视图的总高度。此外，当前代码未将图像加载到图像视图中。

<androidx.constraintlayout.widget.ConstraintLayout
    android:id="@+id/constraintAList"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="5dp">

    <com.google.android.material.imageview.ShapeableImageView
        android:id="@+id/audioThumb"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"
        android:background="@drawable/ic_headset"
        android:scaleType="centerCrop"
        app:layout_constraintDimensionRatio="1:1"
        app:layout_constraintBottom_toBottomOf="@id/audioDetail"

    <TextView

        app:layout_constraintStart_toStartOf="@id/audioTime"
        app:layout_constraintTop_toBottomOf="@+id/audioTime" />

</androidx.constraintlayout.widget.ConstraintLayout>
