I'm going to achieve this goal using ConstraintLayout:
The length of each TextView is not fixed and may change and the TextViews should be in the middle of their columns. I guessed that barriers and guidelines could help me if I chain barrier_left and barrier_right using app:layout_constraintHorizontal_chainStyle="spread_inside", so I checked it out:

</androidx.constraintlayout.widget.ConstraintLayout>
but it didn't work at all! It is the result:
And this is my Design Surface:
I need to keep all Views on the screen (none of them should go out) and each View should place in the center of its column. I need to give some space from the Middle column to the left or right column if left or right ones are longer and need space. How can I arrange the Views like the one shown in the first image?
