How to change default images of CheckBox

Question

I am using ListView and for every row I have row_item.xml and I inflate that in code

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <CheckBox
        android:id="@+id/chk"
        android:layout_alignParentLeft="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    <TextView
        android:id="@+id/txtChoice"
        android:textColor="#FF0000"
        android:text="TEST"
        android:layout_toRightOf="@id/chk"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" /> 
</RelativeLayout>

Drawable customdrawablecheckbox.xml:

<?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/unchecked_drawable" />
     <item android:state_checked="true" android:drawable="@drawable/checked_drawable" />
     <item android:drawable="@drawable/unchecked_drawable" /> <!-- default state -->
</selector>

yourcheckbox xml:

<CheckBox
    android:id="@+id/chk"
    android:button="@drawable/customdrawablecheckbox"
    android:layout_alignParentLeft="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />
