How to make an Custom Alert Dialog width larger?

Question

Actually i have a custom AlertDialog in my app, but i've implemented in it an SegmentButton that is not fitting properly in the AlertDialog as you can see on the screen below.

Obviously i would prefer to resize and make fit the elements from just the SegmentButton if it's possible but if not it would be anyway great to make the entire AlertDialog larger

So i would know if is it possible to make that alert Dialog larger in width.

Here is my XML code for the custom AlertDialog

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"


    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:gravity="center"

    android:focusableInTouchMode="true"

    android:background="#20d2d2d2"

    android:orientation="vertical">

Answer 1

Solved by adding the following code below my AlertDialog method

 dialog.getWindow().setBackgroundDrawableResource(R.color.semitransparent);

Idk why but it solved my problem by making AlertDialog larger
