Custom checkbox image android

Is there an easy way to use a custom image for a checkbox? I'm looking to duplicate the "starred" behavior of gmail. So I want to have a checkbox that, when checked, is a filled in star. And when unchecked is an empty star. Do I have to use an imageview and do my own logic myself?

Based on the Enselic and Rahul answers.

It works for me (before and after API 21):

<CheckBox
    android:id="@+id/checkbox"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:text=""
    android:gravity="center"

    android:background="@drawable/checkbox_selector"
    android:button="@null"
    app:buttonCompat="@null" />

If you are using custom adapters than android:focusable="false" and android:focusableInTouchMode="false" are nessesury to make list items clickable while using checkbox.

<CheckBox
        android:id="@+id/checkbox_fav"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:button="@drawable/checkbox_layout"/>

In drawable>checkbox_layout.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:drawable="@drawable/uncked_checkbox"
        android:state_checked="false"/>
    <item android:drawable="@drawable/selected_checkbox"
        android:state_checked="true"/>
    <item android:drawable="@drawable/uncked_checkbox"/>
</selector>

If you use androidx.appcompat:appcompat and want a custom drawable (of type selector with android:state_checked) to work on old platform versions in addition to new platform versions, you need to use

    <CheckBox
        app:buttonCompat="@drawable/..."

instead of 

    <CheckBox
        android:button="@drawable/..."

Adding custom drawable in the android:button did not work for me in Material Checkbox version-1.3.0 . I had to set android:drawable="@drawable/checkbox_selector" instead and also set android:button="@null" . You can also add android:drawablePadding to make it look good. However, this makes the entire checkbox clickable (along with the text).
