How to change the font size of a preference?

I don't know how to change the font size of a few preferences. I have tried this post but it didn't work. After doing it, my icon did not show up. This is what it looks like now but I think that the title of the Preference is too big. Here is what my screen currently looks like:

Here is the code for my pref_headers.xml xml file:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <Preference
        android:key="@string/key_pref_general"
        android:title="@string/label_pref_general"
        android:icon="@drawable/ic_person"/>

        <Preference
            android:key="@string/key_pref_categories"
            android:title="@string/label_pref_categories"
            android:icon="@drawable/ic_list"/>

        <Preference
            android:key="@string/key_pref_productivity"
            android:title="@string/label_pref_productivity"
            android:icon="@drawable/ic_chart"/>

        <Preference
            android:key="@string/key_pref_delete"
            android:title="@string/label_pref_delete"/>


</PreferenceScreen>

If you're trying to change the icon size in a preference screen use this method I found out after playing around a bit (inspired by @S-R answer)

Let's say you have 48dp icons which are too big for the Preferences, scale it to 36dp:

<style name="AppPreferenceTheme" parent="@style/PreferenceThemeOverlay.v14.Material">
        <item name="android:layout_width">36dp</item>
        <item name="android:layout_height">36dp</item>
</style>

<!-- And set preference Theme in your Main Theme-->
<style name="YourTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="preferenceTheme">@style/AppPreferenceTheme</item>
</style>

For some reason, this only effects the ImageView and not the text or checkboxes or what ever in the screen. Please test before using ...

You can also change it in your style

 <!-- Custom Preference Theme inherits from the v14 support library Material Theme -->
<style name="AppPreferenceTheme" parent="@style/PreferenceThemeOverlay.v14.Material">
    <item name="android:textSize">14sp</item>
</style>

<!-- And set preference Theme in your Main Theme-->
<style name="YourTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="preferenceTheme">@style/AppPreferenceTheme</item>
</style>

I have one solution for you.you can change font size for specific preference by managing layout file.

Here is your edited pref_headers.xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
    android:key="general"
    android:title="General"
    android:icon="@drawable/ic_person_black_24dp"
    android:layout="@layout/font_layout"/>

<Preference
    android:key="categories"
    android:title="Categories"
    android:icon="@drawable/ic_list_black_24dp"
    android:layout="@layout/font_layout"/>

<Preference
    android:key="productivity"
    android:title="Productivity"
    android:icon="@drawable/ic_timeline_black_24dp"
    android:layout="@layout/font_layout"/>

<Preference
    android:key="delete_this_accnt"
    android:title="Delete this Account"
    android:layout="@layout/font_layout"/>
</PreferenceScreen>

Here is the layout(font_layout.xml) file from which you can change font size or any attribute which you want to change like color etc.:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="8dp"
android:gravity="center"
android:orientation="horizontal">
<ImageView
    android:id="@android:id/icon"
    android:layout_width="40dp"
    android:paddingStart="4dp"
    android:paddingEnd="4dp"
    android:layout_height="40dp" />

<TextView
    android:id="@android:id/title"
    android:layout_weight="1"
    android:layout_width="0dp"
    android:textColor="#201f1f"
    android:layout_height="wrap_content"
    android:textSize="18sp" />
</LinearLayout>

Hope this helps!

        android:title="@string/label_pref_delete"/>

</PreferenceCategory>
