Change font typeface of summary of `ListPreference`

I tried with THIS LINK to change the typeface of all preferences of PreferenceScreen. It was changed everywhere except summary of ListPreference. Can anyone has an idea how to apply custom font on summary of ListPreference?

UPDATE

I want to apply my custom font exist on assets folder, not the in-build one. Also android:textAppearanceListItemSecondary required API 21, my app support minimum API 15.

Finally the way to change the font for summary of ListPreference.

Override the onBindViewHolder method of ListPreference to set your custom typeface. Check below custom class.

public class CustomListPreference extends ListPreference {
private String typefaceTitle, typefaceSummary;

public CustomListPreference(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
    super(context, attrs, defStyleAttr, defStyleRes);
    init(context, attrs);
}

public CustomListPreference(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    init(context, attrs);
}

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

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

@Override
public void onBindViewHolder(PreferenceViewHolder holder) {
    super.onBindViewHolder(holder);
    if(!TextUtils.isEmpty(typefaceTitle)) {
        TextView titleView = (TextView) holder.findViewById(android.R.id.title);
        titleView.setTypeface(FontManager.getInstance().getFont(typefaceTitle));
    }
    if(!TextUtils.isEmpty(typefaceSummary)){
        final TextView summaryView = (TextView) holder.findViewById(
                android.R.id.summary);
        summaryView.setTypeface(FontManager.getInstance().getFont(typefaceSummary));
    }
}

private void init(Context context, AttributeSet attrs){
    TypedArray a = context.obtainStyledAttributes(attrs,
            R.styleable.Preference);

    typefaceTitle = a.getString(R.styleable.Preference_typefaceTitle);
    typefaceSummary = a.getString(R.styleable.Preference_typefaceSummary);

    a.recycle();
}}

attrs.xml

<declare-styleable name="Preference">
    <attr name="typefaceTitle" format="string"></attr>
    <attr name="typefaceSummary" format="string"></attr>
</declare-styleable>

Usage in Preference screen.

<YOUR_CustomListPreference_PACKAGE_NAME.CustomListPreference
        android:defaultValue="X"
        android:dialogTitle="Dialog Title"
        android:entries="@array/list_item_title"
        android:entryValues="@array/list_item_value"
        android:key="pref_list"
        android:summary="%s"
        android:title="@string/Preference Title"
        app:typefaceTitle="YOUR FONT NAME"
        app:typefaceSummary="YOUR FONT NAME"/>

Hope this help for other.

try this 

 <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="android:textAppearanceListItemSecondary">@style/textAppearanceListItemSecondaryCustom</item>
    </style>


    <style name="textAppearanceListItemSecondaryCustom">
        <item name="android:textSize">14sp</item>
        <item name="android:typeface">monospace</item>
    </style>
