How can I change font size in PreferenceScreen
<pre><code>&lt;PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"&gt;
    &lt;PreferenceCategory
        android:title="First Category"
        android:textSize="20px"&gt;

        &lt;CheckBoxPreference
            android:title="Checkbox Preference"
            android:defaultValue="false"
            android:summary="This preference can be true or false"
            android:key="checkboxPref" /&gt;

    &lt;/PreferenceCategory&gt;
&lt;/PreferenceScreen&gt;
</code></pre>

<p>I need to change <code>android:title</code> font size of <code>PrefereceCategory</code>, <code>CheckboxPreference</code> and <code>android:summary</code> size. These tags don't have any <code>android:textSize</code> attribute. Can any one help me how to get this?</p>
