If you need to customize the radio button look..

Create a selector xml (radio_btn_selector.xml) in the drawable folder as.

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/pressed_image" 
    android:state_pressed="true"/>  
<item android:drawable="@drawable/checked_image" 
    android:state_checked="true"/>  
<item android:drawable="@drawable/focused_image" 
    android:state_focused="true" />
<item android:drawable="@drawable/default_image" />  
</selector> 

Now use the selector as button type in the Radio Button.

<RadioButton
            android:id="@+id/radioButton2"
            android:layout_width="105dp"
            android:layout_height="fill_parent"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true"
            android:background="@null"

android:button="@drawable/radio_btn_selector"/>
