<radiogroup             android:id="@+id/eligibility"             android:layout_height="wrap_content"             android:layout_width="0dp"             android:orientation="horizontal"             android:layout_weight=".5" >              <radiobutton                 android:id="@+id/eligibilityyes"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:checked="true"                 android:background="@drawable/checkbox_background"                 android:text="yes" />              <radiobutton                 android:id="@+id/eligibilityno"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:background="@drawable/checkbox_background"                 android:text="no" />         </radiogroup>

your checkbox_background.xml file put image in res/drawable

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