Remove ripple effect from RadioButton, android?

Question

I have custom styled a RadioButton for adding radiobutton image on the right side

<RadioButton
                android:layout_margin="20dp"
                android:drawableRight="@drawable/custom_btn_radio"
                android:button="@null"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Invite Only"/> 

custom_btn_radio.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/check_box" android:state_checked="false"/>
    <item android:drawable="@drawable/close_btn" android:state_checked="true"/>
</selector>

but, the radiobutton's ripple effect also enlarged. how can i remove ripple effect from RadioButton? and also how to customize ripple effect?

Thank you in advance.

Make RadioButton background to transparent

android:background="#ffffffff"

or

android:background="@android:color/transparent"
