View on the right only if their is enough space, otherwise go at the bottom

Using the ConstraintLayout I have 2 TextView that I want to be next to each other when their is enough space to see the content of both. But if TextView A takes a lot of space and fullfill all the screen width, than I would like that TextView B goes under TextView A instead of still being on the right but invisible (out of the screen).

So with the code below I got my 2 TextView right next to each other.

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

    <TextView
        android:id="@+id/text_view_a"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="8dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:layout_marginTop="8dp"
        tools:text="a very long text ..." />

    <TextView
        android:id="@+id/text_view_b"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="8dp"
        app:layout_constraintLeft_toRightOf="@+id/text_view_a"
        app:layout_constraintTop_toTopOf="parent"
        tools:text="some text" />

</android.support.constraint.ConstraintLayout>

How should I edit this code snippet so that TextView B goes under TextView A if their isn't any space left for him?

I just had to add this answer since as much as the accepted answer works,id recommend a different approach using the currently existing constraint layout of which its usage is highly recommended due to UI performance advantages.its as simple as adding a androidx.constraintlayout.helper.widget.Flow and setting the reference id of the views to flow:

<androidx.constraintlayout.widget.ConstraintLayout 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:orientation="vertical">

    <TextView
        android:id="@+id/text1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="[AAAAAAAA]"
        tools:ignore="MissingConstraints" />

    <TextView
        android:id="@+id/text2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="[BBBBBBBB]"
        tools:ignore="MissingConstraints" />

    <TextView
        android:id="@+id/text3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="[CCCCCCCC]"
        tools:ignore="MissingConstraints" />

    <TextView
        android:id="@+id/text4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="[DDDDDDDD]"
        tools:ignore="MissingConstraints" />

    <TextView
        android:id="@+id/text5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="[EEEEEEEE]"
        tools:ignore="MissingConstraints" />

    <TextView
        android:id="@+id/text6"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="[FFFFFFFF]"
        tools:ignore="MissingConstraints" />

    <androidx.constraintlayout.helper.widget.Flow
        android:id="@+id/flow1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:padding="10dp"
        app:constraint_referenced_ids="text1,text2,text3,text4,text5,text6"
        app:flow_horizontalBias="0"
        app:flow_horizontalGap="10dp"
        app:flow_horizontalStyle="packed"
        app:flow_verticalBias="0"
        app:flow_wrapMode="chain"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
