Positioning in a ConstraintLayout

Question

I have three views: a TextView, a LinearLayout and a Switch inside a ConstraintLayout:

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

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

    <TextView
        android:id="@+id/tTextView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="15dp"
        app:layout_constraintHorizontal_bias="0.0"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:text="Some text" />

        <LinearLayout
            android:id="@+id/linearLayout"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            app:layout_constraintHorizontal_bias="0.5"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent">

            <TextView
                android:id="@+id/tv1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="text1" />

            <TextView
                android:id="@+id/tv2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="text2" />

            <TextView
                android:id="@+id/tv3"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="text3" />

            <TextView
                android:id="@+id/tv4"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="text4" />

            <TextView
                android:id="@+id/tv5"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="text5" />

            
        </LinearLayout>

        <Switch
            android:id="@+id/switch1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginEnd="15dp"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constrainedWidth="true"
            app:layout_constraintHorizontal_bias="1.0"
            app:layout_constraintEnd_toEndOf="parent" />

    </androidx.constraintlayout.widget.ConstraintLayout>

</merge>

I want the TextView to be 15dp from the left, the LinearLayout at the centre and the Switch 15dp from the right. But they all are on the left. I tried using app:layout_constrainedWidth="true" for all the three views, changing some attributes and constraints, but none of them worked, though some were displayed as expected in Android Studio's layout preview, but they clutter to the left at runtime. I'm not sure if ConstraintLayout is the best option either. As you can see, this is for a custom view.
