Problems styling ActionBar background with Drawable

I have tried to add a image to the ActionBar background using this theme/style
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:background">#drawable/actionbar_background</item>
</style>
But although the background is being changed, it's creating a weird effect on the title and menu button. It's as thought they are separate child views within the ActionBar (maybe they are, I'm not sure) and the Drawable is being applied to them individually.
I was hoping for a seamless Drawable being applied across the ActionBar. Is this possible or should I just give up, and instead just change the background with a flat colour?

When you set the android:theme attribute of a view, the style you pass is applied to that view and all of its children. In your case, the AppBarLayout does (internally) use separate views for the title and the overflow menu button.
However, since the only thing your style seems to be doing is setting the android:background attribute, you could just set that directly on the AppBarLayout. So, replace this:
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
with this:
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/actionbar_background">

"android:background"
in your style change the background to each component in your layouts.
You can change the color of your ActionBar with something like this.
<item name="android:navigationBarColor">#color/colorPrimary</item>

This is an example for the AppCompat-v7 Toolbar, the other Toolbar is a bit different when it comes to theme.
I can't really give you the answer that will suit you the most, and this code is only here to show you the way.
What changes is that the toolbar is using style instead of android:theme and it uses a new style AppTheme.Toolbar.
AppTheme.Toolbar groups your custom background, the theme for the views inside the toolbar (title, subtitle, etc) and the theme for the popup menu.
The theme for the children and the popup menu are separated so you can control each component separately.
Try to play with their parent attribute (from Dark to Light) and pick what is the best for you.
Into your styles.xml
<style name="AppTheme.Toolbar">
<item name="android:background">#drawable/actionbar_background</item>
<item name="popupTheme">#style/AppTheme.PopupOverlay</item>
<item name="android:theme">#style/AppTheme.AppBarOverlay</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
<!-- Change attribute of the toolbar views-->
</style>
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Dark">
<!--Change attribute of the menu-->
</style>
Into your activity_main.xml
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
style="#style/AppTheme.Toolbar"
android:layout_height="?attr/actionBarSize" />
</android.support.design.widget.AppBarLayout>

what i can do to achieve toolbar shown in first image

ActionBar style (Text size)

I'm trying to modify the text size of my ActionBar and I tried styling it but it doesn't change anything... That's my styles page.
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/AppTheme.Styled.ActionBar.TitleTextStyle</item>
<!-- Customize your theme here. -->
</style>
<style name="AppTheme.ActionBar">
<item name="android:titleTextStyle">#style/AppTheme.Styled.ActionBar.TitleTextStyle</item>
</style>
<style name="AppTheme.Styled.ActionBar.TitleTextStyle" parent="#android:style/Widget.TextView">
<item name="android:textSize">19sp</item>
</style>
Also I had this on my styles.xml but doesn't work either
<style name="Theme.FixedSize" parent="#android:style/Theme.Holo.Light.DarkActionBar">
<item name="actionBarSize">4dip</item>
<item name="android:actionBarSize">4dip</item>
<item name="android:textSize">3sp</item>
</style>
I also have tried with a nasty way but it doesn't work only works with the color.
mActionBar.setTitle(Html.fromHtml("<font size=\"3\" color=\"white\">" + getString(R.string.app_name_device)));
After you say to me... I know now it's used Toolbar BUT I have to do it now with ActionBar.
EDIT
I hided the ActionBar like this :
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<!-- Customize your theme here. -->
</style>
Then I added a ToolBar like this :
<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_width="match_parent"
android:layout_height="?actionBarSize"
android:id="#+id/toolbar"
app:titleTextAppearance="#style/Toolbar.TitleText" />
But the Layout messed up, it goes up and now the ToolBar is collapsed with the first TextView

You can do it programmatically like this
Html.fromHtml("<big><font color=\"white\">" + getString(R.string.app_name_device)+"</big>")
for small text you can change tag <big> with <small>
and if you want to provide specific size of Title Text then you should use Toolbar and use below theme/style
Create one layout toolbar.xml and put below code
<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_width="match_parent"
android:layout_height="?actionBarSize"
android:id="#+id/toolbar"
app:titleTextAppearance="#style/Toolbar.TitleText" />
and change size in
<style name="Toolbar.TitleText" parent="TextAppearance.Widget.AppCompat.Toolbar.Title">
<item name="android:textSize">18sp</item>
</style>
and you can inculde above layout in your each Activity layout files like below
<include
layout="#layout/toolbar"
/>
Toolbar in your Activity
ToolBar mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setTitle(Html.fromHtml("<big><font color=\"white\">" + getString(R.string.app_name_device)+"</big>"));

I do it so:
import android.support.v7.app.ActionBar;
public void title_change(String text) {
TextView tv = new TextView(this);
tv.setText(text);
tv.setTextSize(15);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(tv);
}

Android: How to remove line between Toolbar and Statusbar

I am interested in having a uniform coloured toolbar and status bar. If I provide colorPrimary and colorPrimaryDark as the same colour this should be possible. I am getting the desired result using ActionBar but not with Toolbar. I will also be creating a navigation view so i need the status bar as transparent.
Code : Styles-v21
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
</style>
Code : Styles
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimary</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar"/>
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light"/>
</resources>
Steps to reproduce :
Create a new project in android studio with Navigation Drawer Activity
Set primary and primaryDark as same colours
Run on device or emulator

The only solution I could come up with was to remove android:fitsSystemWindows="True" from Coordinator Layout
edit : Another solution is to wrap coordinator layout in another coordinator layout.
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<include
layout="#layout/content_main"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
</android.support.design.widget.CoordinatorLayout>
Before
After

This shadow you are seeing is window content overlay, you could remove it:
Please add this line to your theme specification:
<item name="android:windowContentOverlay">#null</item>

AppCompat toolbar dark theme style not working on pre 21 devices

First of all I have repeatedly read and applied everything posted here, but it does not solve my problem. It seems that every answer posted here is to apply style to theme attribute of the toolbar, i've tried it it got me nowhere, so let me explain what my problem is:
I want to have light theme everywhere except the toolbar. On Lollipop devices, it's not a problem, but on pre Lollipop devices toolbars Title and overflow button always adopts MyTheme parent style, so I get dark Title and dark overflow button (it's my only button there) it seems like theme attribute is malfunctioning in Toolbar.
I'm using AppCompatActivity for my base class, my minimum api is 15 and AppCompat version is 22.2.1.0
Here's my code:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
local:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
local:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
<style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="colorPrimary">#color/primary_color</item>
<item name="colorPrimaryDark">#color/dark_primary_color</item>
<item name="colorAccent">#color/accent_color</item>
<item name="android:statusBarColor">#color/dark_primary_color</item>
<item name="selectableItemBackground">?android:attr/selectableItemBackground</item>
</style>
my hamburger item is white because I inflate image from resource
var toolbar = FindViewById<Toolbar>(Resource.Id.toolbar);
SetSupportActionBar(toolbar);
SupportActionBar.Title = "Sport";
if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop)
Window.AddFlags(WindowManagerFlags.DrawsSystemBarBackgrounds);
if (SupportActionBar != null){
SupportActionBar.SetHomeAsUpIndicator(Resource.Drawable.ic_menu_white_24dp);
SupportActionBar.SetDisplayHomeAsUpEnabled(true);
}

<?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_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
app:theme="#style/ThemeOverlay.AppCompat.Dark"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
>
</android.support.v7.widget.Toolbar>
Try This combination in your toolbar code it should work just fine.

This is what worked for me in the end:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
local:titleTextColor="#android:color/white"
local:theme="#style/ToolbarTheme"
local:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<style name="ToolbarTheme" parent="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:background">#color/primary_color</item>
<!-- Used to for the title of the Toolbar -->
<item name="android:textColorPrimary">#fff</item>
<!-- Used to for the title of the Toolbar when parent is Theme.AppCompat.Light -->
<item name="android:textColorPrimaryInverse">#fff</item>
<!-- Used to color the text of the action menu icons -->
<item name="android:textColorSecondary">#fff</item>
<!-- Used to color the overflow menu icon -->
<item name="actionMenuTextColor">#fff</item>
</style>
<style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/primary_color</item>
<item name="colorPrimaryDark">#color/dark_primary_color</item>
<item name="colorAccent">#color/accent_color</item>
<item name="android:statusBarColor">#color/dark_primary_color</item>
<item name="colorControlNormal">#fff</item>
</style>
In this case ColorControlNormal colored overflow icon and titleTextColor colored Title. It seems that in my case ToolbarTheme doesn't work. I don't have a clue why is it, but now I don't care. This is not an optimal solution but it works.
