I have the following layout. In the example below, you will notice that Y was not able to be laid out to its full width, and it was cut-off (truncated) due to the lack of vertical space.

enter image description here

I would like to be able to programmatically identify when this happens (as a Boolean. How can I achieve this?

Note: the answer to this question will enable a workaround for this problem How can I use ConstraintLayout to have the first View shrink to fit remaining space?

<androidx.constraintlayout.widget.ConstraintLayout 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">

<ScrollView
    android:id="@+id/scrollView"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#fbe9e7"
        android:gravity="center"
        android:text="X"
        android:textSize="96sp">

    </TextView>
</ScrollView>

<TextView
