Как настроить высоту вертикального элемента управления в ConstraintLayout в Android Studio?

Я надеюсь установить высоту вертикального элемента управления VerticalSeekBar как максимальную высоту между btnMenu и btnAction .

Но Макет B (результат Изображение B ) не то, что мне нужно, поэтому я должен определить значение высоты VerticalSeekBar как фиксированный 200dp, вы можете увидеть Макет A (В результате Изображение A ).

Кстати, элемент управления VerticalSeekBar размещен на https://github.com/lukelorusso/VerticalSeekBar

попробуйте включить seekBar в другой макет как LinearLayout: 

<LinearLayout
        android:id="@+id/verticalSeekBarLayout"
        android:layout_width="10dp"
        android:layout_height="0dp"
        android:layout_marginRight="30dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintBottom_toTopOf="@+id/btnAction"
        app:layout_constraintTop_toBottomOf="@+id/btnMenu"
        android:orientation="vertical">

        <com.lukelorusso.verticalseekbar.VerticalSeekBar
            android:id="@+id/verticalSeekBar"
            android:layout_width="10dp"
            android:layout_height="match_parent"
            android:layout_marginRight="30dp" />
    </LinearLayout>
