I asked this question because I didnt like the defualt style of checkoboxes,while I needed radibutton surely.So I put radioGroup on my app and then change android:button with a checkbox_selector(with my favorite pictures ) which I created it. a cb_selector like this :

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:drawable="@drawable/checked2" />
    <item android:state_checked="false" android:drawable="@drawable/unchecked2" />
</selector>

this must write in a xml file in drawable forlder. then i write @drawable/cb_selector in Button property for each radiobutton in my radioGroup.
