android - 约束布局约束尺寸比不适用于多个视图

Question

我遇到了约束尺寸比的问题。图像视图的宽度和高度未调整。我想根据比例制作图像拇指视图正方形。我希望图像拇指的宽度和高度等于布局中给出的三个文本视图的总高度。当前代码也没有将图像加载到图像视图中。

<androidx.constraintlayout.widget.ConstraintLayout
    android:id="@+id/constraintAList"

对于图像视图

• 设置android:layout_height="0dp"和
• 消除app:layout_constraintEnd_toStartOf="@id/audioName"
