Android – the round button becomes distorted with the length of the text inside

I want a perfect round button

I try to use the following code to use shapes. But the problem I face is that when there are two text in the view, it looks almost a circle, but as long as there are one and three characters in the view, it will look oval

Shape code

  <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval"
    android:useLevel="true">


       <corners android:bottomRighTradius="20dip"
        android:bottomLefTradius="20dip"  
        android:topRighTradius="20dip"
        android:topLefTradius="20dip"
        />


       </shape>

Please check the almost circular buttons, which are marked with numbers 2 and 22. I used the same code for all buttons (as described above)

resolvent:

In the layout file (or code), keep the size of the button fixed (width = height = some DP). For example:

layout_width="48dp"
layout_height="48dp"
