Constrain Layout : Defining Seekbar height with respect to other fields - android-constraintlayout

Question

I am adding a couple of Textviews and a Seekbar in a Constraint Layout. I have defined textview height according to the screen height and want the seekbar height to go from one textview to the other. The code is
<TextView
android:id="#+id/detailTaskHighTextId"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintHorizontal_bias="0.1"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.45"
android:text="High"/>
<TextView
android:id="#+id/detailTaskLowTextId"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintHorizontal_bias="0.1"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.75"
android:text="Low"/>
<SeekBar
android:id="#+id/detailTaskPriorityId"
style="#style/Widget.AppCompat.SeekBar.Discrete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:max="3"
android:progress="3"
android:rotation="270"
android:visibility="visible"
app:layout_constraintBottom_toBottomOf="#id/detailTaskLowTextId"
app:layout_constraintTop_toTopOf="#id/detailTaskHighTextId"
app:layout_constraintLeft_toRightOf="#id/detailTaskHighTextId"/>
I don't want to hardcode the seekbar width. The seekbar width is really small here. Using the Top_toTopOf and Bottom_toBottomOf just brings seekbar in the middle of the two text views. I tried Start_toStart and End_toEnd as well. What am I missing? This is what I am seeing Link to image

You need to change height (using MATCH_CONSTRAINT) of seek bar like this:
<SeekBar
android:id="#+id/detailTaskPriorityId"
style="#style/Widget.AppCompat.SeekBar.Discrete"
android:layout_width="wrap_content"
android:layout_height="0dp" <- MATCH_CONSTRAINT
android:max="3"
android:progress="3"
android:rotation="270"
android:visibility="visible"
app:layout_constraintBottom_toBottomOf="#id/detailTaskLowTextId"
app:layout_constraintTop_toTopOf="#id/detailTaskHighTextId"
app:layout_constraintLeft_toRightOf="#id/detailTaskHighTextId"/>
