How to fit all buttons in one row?

Question

I'm doing the hangman game but I have seriously problem with the layout. What i want to do is to fit all the letters in two row, and each letter has a button where the user can click on. I tried everything but i can't fix the buttons that do not shrink. I would be very happy if someone tell me what's the problem. Thank you!

here the activity_main.xml

            </TableRow>
        </TableLayout>

    </LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

and here the style that I used for each button:(Stilepulsanti)

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="StilePulsanti">
        <item name="android:gravity">center_vertical|center_horizontal</item>
        <item name="android:layout_width">wrap_content</item>
        <item name="android:layout_height">wrap_content</item>
        <item name="android:textSize">15dp</item>
        <item name="android:background">#54AEDB</item>
        <item name="android:clickable">true</item>
    </style>
</resources>

Answer 1

If you want your buttons to shrink, add <item name="android:layout_weight">1</item> to your StilePulsanti style.

Your letters may not be visible after adding this, because you used too many buttons in one row. I suggest you add more rows to avoid this.
