android.support.v7.widget.AppCompatCheckBox fontfamily not applied on runtime

Question

I am updating font in my application by using the support library. Font is not getting updated on AppCompatCheckBox at runtime but in layout preview it is working fine. There are two styles.xml files in my application and I applied AppBaseTheme to all my activities.

default styles.xml

<style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.
    -->
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="colorPrimaryDark">@color/material_blue_700</item>
    <item name="colorPrimary">@color/material_blue_500</item>

    <!-- Android widgets styles overridden -->

    <item name="android:checkboxStyle">@style/AppCheckBoxStyle</item>
    <item name="checkboxStyle">@style/AppCheckBoxStyle</item>

    <item name="android:radioButtonStyle">@style/AppRadioButtonStyle</item>
    <item name="radioButtonStyle">@style/AppRadioButtonStyle</item>


</style>

<style name="AppCheckBoxStyle" parent="android:Widget.CompoundButton.CheckBox">
    <item name="android:fontFamily">@font/allura_regular</item>
</style>

<style name="AppRadioButtonStyle" parent="android:Widget.CompoundButton.RadioButton">
    <item name="android:fontFamily">@font/allura_regular</item>
</style>

v21/styles.xml

<style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!--

        res/values-vXX/styles.xml, while customizations related to

Yes, android:fontFamily does not work with AppCompatCheckbox. You can create a custom checkbox widget like this, and use it for your purpose.

public class MyCustomCheckBox extends AppCompatCheckBox {
    public MyCustomCheckBox(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    public MyCustomCheckBox(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public MyCustomCheckBox(Context context) {
        super(context);
    }

    private void init() {
        Typeface tf = Typeface.createFromAsset(getContext().getAssets(),
                "poppins_light.ttf");
        setTypeface(tf);
    }
}
