Set Title style for PreferenceCategory in PreferenceFragmentCompat

Question

I want to set title style for my preference fragment screen V14.
This is what I want:

I have followed
Custom PreferenceCategory Headings
I did manage to get the same screen but with PreferenceFragment!!
How can I do it for PreferenceFragmentCompat V14??

Here is my Code

Style.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:listSeparatorTextViewStyle">@style/PreferenceStyle</item>
    <item name="preferenceTheme">@style/PreferenceThemeOverlay.v14.Material</item>
</style>

<style name="PreferenceStyle" parent="@android:style/Widget.TextView">
    <item name="android:textColor">@color/colorDialogPop</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textSize">@dimen/text_medium</item>
    <item name="android:padding">@dimen/padding_large</item>
    <item name="android:layout_marginLeft">@dimen/margin_medium</item>
    <item name="android:background">@color/colorAccent</item>
</style>

preference.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

<PreferenceCategory android:title="@string/heading_general"
    android:layout="@layout/settings_text">

    <SwitchPreference
        android:padding="@dimen/padding_medium"
        android:title="@string/enable_push" />

    <SwitchPreference
        android:padding="@dimen/padding_medium"
        android:title="@string/send_email" />

</PreferenceCategory>

<PreferenceCategory android:title="@string/heading_account"
    android:layout="@layout/settings_text">

    <EditTextPreference
        android:padding="@dimen/padding_medium"
        android:title="@string/email" />

    <EditTextPreference
        android:padding="@dimen/padding_medium"
        android:title="@string/name" />

</PreferenceCategory>
</PreferenceScreen>

setting_text.xml for layout of title text

<TextView xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@android:id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="@style/PreferenceStyle"

SOLVED
I added the Linear Layout around the Text View and the background gets visible in my choice of color.
Here is the code.

settings_text.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content">

<TextView
    android:id="@android:id/title"
    style="@style/CustomPreferenceCategoryText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />
</LinearLayout>

style.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="preferenceTheme">@style/PreferenceStyle</item>
</style>

<style name="PreferenceStyle" parent="@style/PreferenceThemeOverlay.v14.Material">
    <item name="preferenceCategoryStyle">@style/CustomPreferenceCategory</item>
</style>

<style name="CustomPreferenceCategory" parent="@style/Preference.Category">
    <item name="android:layout">@layout/settings_text</item>
</style>

<style name="CustomPreferenceCategoryText" parent="@android:style/Widget.TextView">
    <item name="android:textColor">@color/colorDialogPop</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textSize">@dimen/text_medium</item>
