如何使ConstraintLayout自动调整其高度？

Question

无论我在layout_height中输入什么，ConstraintLayout的高度似乎与手机屏幕尺寸相同。有什么方法可以设计它自动适应其高度与其内容的总高度？

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    tools:context="stfn.personaltrainer.activities.Training">

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="10dp">

        <TextView
            android:id="@+id/exerciceName"
            android:layout_width="277dp"
            android:layout_height="41dp"
            android:layout_marginTop="4dp"
            android:text="Exercice name"
            android:textAlignment="center"
            android:textSize="36sp"
            app:layout_constraintHorizontal_bias="0.504"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

        <!-- TextViews, Buttons, etc. -->

        <Button
            android:id="@+id/repetitionsDone"
            android:layout_width="118dp"
            android:layout_height="wrap_content"
            android:layout_marginTop="50dp"
            android:onClick="goToNextSeries"
            android:text="@string/done"
            android:textAppearance="@style/TextAppearance.AppCompat.Button"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/repetitionsInCurrentSeries" />

    </android.support.constraint.ConstraintLayout>

</ScrollView>

更改布局的高度以填充整个屏幕：

    android:layout_height="match_parent"
