You might want to create your own CheckBox custom style, and RadioButton custom style in Android, for your applications.

This is how you can achieve it, in a few steps:
-Create Image Drawables for their two stater (checked/unchecked).
-Create selector for this two drawables. The sample content should be something 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/unchecked" />
	<item android:state_checked="false" android:drawable="@drawable/checked" />
</selector>

-Add this selector as android:button attribute for CheckBox or RadioButton

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/background">

    <CheckBox
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:button="@drawable/checkbox_selector"
        android:text="Custom CheckBox" />

    <RadioButton
        android:id="@+id/radioButton1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:button="@drawable/checkbox_selector"
        android:text="Custom RadioButton" />

</LinearLayout>
