Support Action Bar not applying my style?

Question

I've been spending hours trying to fix the changing action bar title size according to this stack overflow post: Android Toolbar: small title text in landscape mode

Unfortunately, it seems that no matter what I do, anything regarding the actionbar style won't actually apply.

My styles v14 file:

<!-- Main theme -->
<style name="MyTheme" parent="Theme.AppCompat">
    <item name="android:actionBarItemBackground">@drawable/selectable_background</item>
    <item name="android:popupMenuStyle">@style/PopupMenu</item>
    <item name="android:dropDownListViewStyle">@style/DropDownListView.MyTheme</item>
    <item name="android:actionBarTabStyle">@style/ActionBarTabStyle.MyTheme</item>
    <item name="android:actionDropDownStyle">@style/DropDownNav.MyTheme</item>
    <item name="android:spinnerItemStyle">@style/Widget.MyTheme.TextView.SpinnerItem</item>
    <item name="android:spinnerDropDownItemStyle">@style/Widget.MyTheme.DropDownItem</item>
</style>

My ActionBar styles:

<style name="Widget.MyTheme.ActionBar" parent="@style/Widget.AppCompat.ActionBar.Solid">
    <item name="android:background">@drawable/ab_solid</item>
    <item name="android:titleTextStyle">@style/my_title_style</item>
</style>

<style name="my_title_style" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
    <item name="textSize">20sp</item>
</style>

And, of course, "MyTheme" is applied in the manifest as well - I've even tried adding it to all the individual activities as well, to no avail.

It seems that no matter what I do, stuff just won't apply. I've tried removing the android: namespace, I've tried using titleTextAppearance instead of titleTextStyle, I've basically emulated exactly how the parent themes do it, but it won't change anything. Anybody have a clue as to what's going on? I just recently updated to AppCompat so I'm not totally familiar with how everything works.

You need to use

<item name="background">@drawable/ab_solid</item>
<item name="titleTextStyle">@style/my_title_style</item>

for support library compatibility into your style.

Read Styling the Action Bar, section "For Android 2.1 and higher". Where it is given that you need to use two entries like

<style name="CustomActionBarTheme"
           parent="@style/Theme.AppCompat.Light.DarkActionBar">
        <item name="android:actionBarStyle">@style/MyActionBar</item>

        <!-- Support library compatibility -->
        <item name="actionBarStyle">@style/MyActionBar</item>
    </style>

So your complete style would be

<style name="Widget.MyTheme.ActionBar" parent="@style/Widget.AppCompat.ActionBar.Solid">
    <item name="android:background">@drawable/ab_solid</item>
    <item name="android:titleTextStyle">@style/my_title_style</item>
    <item name="background">@drawable/ab_solid</item>
    <item name="titleTextStyle">@style/my_title_style</item>
</style>

I don´t know if it's all that ou have made, but you have to add this code in the manifest(in the activity you want to apply this style):

<activity
    android:name=".MyActivity"
    android:label="@string/appName"
    android:theme="@style/my_little_style" >
</activity>

Try in this way:

Create a layout for your Toolbar and put a TextView:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_height="?attr/actionBarSize"
    android:layout_width="match_parent"
    android:id="@+id/toolbar"
    android:background="#b2b2b2">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:id="@+id/toolbar_title"
        android:textSize="20sp"
        android:textColor="#ff282828"/>

   </android.support.v7.widget.Toolbar>

Include the layout in your .xml:

<include layout="@layout/toolbar_activities"
    android:id="@+id/toolbar_layout"/>

Finally set a title in your java class:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_layout);

TextView mTitle = (TextView) toolbar.findViewById(R.id.toolbar_title);
mTitle.setText("Your Title");
setSupportActionBar(toolbar)
