TextView exceed Constraint if text is too long in ConstraintLayout

I have one TextView aligned to the left and centered vertically. Two groups of ImageView and TextView are both aligned to the right, with two layout configurations, one with image on the right, another with image on the left.

The hello world text can be very long. I want it to expand to fill the whole width without covering up the left text.

I have added app:layout_constraintStart_toEndOf="@id/text1" to constraint the right group (image + text) not to overlap with the left text. However, it does not behave as I expected.

How to make it not overlapping using only ConstraintLayout?

result with short text

Text1 will be covered up if the right text is too long, which is not expected. Be noted that the image on the second row is gone too.
result with long text

code:

</androidx.constraintlayout.widget.ConstraintLayout>

expected to be like below if the right text is too long. It can achieved by LinearLayout and RelativeLayout enter image description here

Kindly check the Constraintlayout version. Use app:layout_constrainedWidth="true" with android:layout_width="wrap_content"

You can use Guidelines to stop your text from expanding more than needed.

let's take this layout for example:

<?xml version="1.0" encoding="utf-8"?>
<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"
  tools:context=".MainActivity">

<TextView
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:gravity="center"
    android:text="longgggggg texttttttttttttttttexttttttttttttttttexttttttttttttttttexttttttttttttttt"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="@+id/guideline2"
    app:layout_constraintTop_toTopOf="parent" />

<TextView
    android:id="@+id/textView"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:text="TextView"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toStartOf="@+id/guideline2"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<androidx.constraintlayout.widget.Guideline
    android:id="@+id/guideline2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    app:layout_constraintGuide_percent="0.18" />

And because of app:layout_constraintGuide_percent="0.18" and android:layout_width="0dp" on both text views the long textView will not exit its constraints.
