Here is an example by radio group which i tried. maybe its helpful for you. just take a look once.

your main xml file

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#655EF9"
    android:orientation="horizontal">

    <CheckBox
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/radiobtn_bck"
        android:button="@null"
        android:checked="true"
        android:gravity="center"
        android:text="S" />

    <CheckBox
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:background="@drawable/radiobtn_bck"
        android:button="@null"
        android:gravity="center"
        android:text="M" />

    <CheckBox
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:background="@drawable/radiobtn_bck"
        android:gravity="center"
        android:button="@null"
        android:text="T" />

</LinearLayout>

here radiobtn_bck xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>

<item android:drawable="@drawable/bg_shape" android:state_checked="true" />
<item android:drawable="@drawable/bg_shape" android:state_pressed="true" />
<item android:drawable="@drawable/bg_shape" android:state_focused="true" />
<item android:drawable="@drawable/bg_shape_purple" android:state_checked="false" />

bg_shape.xml

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

android:shape="oval">
<solid android:color="#ffffff" />
<size
    android:width="40dp"
    android:height="40dp" />

bg_shape_purple.xml

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

android:shape="oval">
<solid android:color="#655EF9" />
<size
    android:width="40dp"
    android:height="40dp" />
