Why the menu of ActionBar didn't change the background

Why the menu of ActionBar didn't change the background - android

I try to custom the ActionBar.
In the Fragment , I use the following code to set ActionBar.
ActionBar actionBar = getActivity().getActionBar();
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setHomeButtonEnabled(false);
actionBar.setCustomView(R.layout.actionbar);
The actionbar.xml is like the following:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/bar_background" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_marginLeft="30dp"
android:layout_marginRight="30dp"
android:src="#drawable/bar_icon"/>
</RelativeLayout >
But it show like the following picture:
Why the menu button didn't change the Background? Did I missing something ?

CustomView is for putting your custom views (e.g. created classes) - Buttons, styled TextViews, other widgets etc. You are looking just for background, so you might use:
actionBar.setBackgroundDrawable(getResources().getDrawable(R.drawable.bar_background));
or (better, prefered) style your ActionBar with styles:
<resources>
<style name="MyTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">#style/MyActionBarTheme</item>
</style>
<style name="MyActionBarTheme" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#drawable/bar_background</item>
</style>
</resources>
with new AppCompat you might use custom, easily colored Toolbar (doc here)

Android - Using custom ActionBar

I have a custom ActionBar layout which I want to use in almost all of my Activities.
The problem is the text doesn't appear.
This is how I use it in an Activity
android.support.v7.app.ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowCustomEnabled(true);
//getSupportActionBar().setDisplayOptions(android.support.v7.app.ActionBar.DISPLAY_SHOW_CUSTOM);
actionBar.setCustomView(R.layout.actionbar_theme);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setTitle("Signup");
But the title "Signup" doesn't appear on the ActionBar..
The theme of the ActionBar
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/actionbar_theme_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_gravity="center"
android:textColor="#color/white" />
</RelativeLayout>
Does this mean that I can't just do setTitle("asdf")?

As of now you can use toolbar as ActionBar and that toolbar can have any custom layout you wish. Here is the reference link.
Declare this in activity xml
<android.support.v7.widget.Toolbar
android:id=”#+id/my_awesome_toolbar”
android:layout_height=”wrap_content”
android:layout_width=”match_parent”
android:minHeight=”?attr/actionBarSize”
android:background=”?attr/colorPrimary” />
Then in java code use
Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);
styles.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>
</style>
for this to work perfectly your Activity should extends AppCompatActivit

This is not how it works. If you set a custom layout to your action bar, you need to change the textview of it like if it was a normal view.
If you are using this layout several time, keep a reference of your action bar or of the viewgroup.
ViewGroup actionBarLayout = (ViewGroup) getLayoutInflater().inflate(R.layout.your layout containing your text view,null);
mActionBar.setCustomView(actionBarLayout);
(TextView)findViewById(R.id.actionbar_theme_title).setText(...)

How to change color of bar in Android App?

I'd like to change color of bar when I use this style:
<style name="AppBaseTheme" parent="#style/Theme.AppCompat.Light" >
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
</style>
For example it should looks like system calculator in Android 5, I mean bar on the top is blue.

you can use
<item name="background">#color/actionbar_background_color</item>

Are you speaking about tool bar. If yes then implement the following xml in your project:
?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:id="#+id/appBar"
android:background="#color/colorPrimary"
app:theme="#style/MyCustomTheme"
android:layout_width="match_parent"
android:layout_height="50dp">
</android.support.v7.widget.Toolbar>
In activity extend your activity to ActionBarActivity, then in onCreate() use the following code:
ToolBar toolbar = (Toolbar) findViewById(R.id.appBar);
setSupportActionBar(toolbar);
Make sure you give blue color for colorPrimary attribute in colors.xml file or you can directly give blue color value if you are not using colors.xml file.

Use the appCompat21 and just set this style:
<style name="Theme.MyTheme" parent="Theme.AppCompat.Light">
<!-- colorPrimary is used for the default action bar background -->
<item name="colorPrimary">#color/my_color</item>
<!-- colorPrimaryDark is used for the status bar -->
<item name="colorPrimaryDark">#color/my_darker_color</item>
</style>

Android: remove left margin from actionbar's custom layout

I am using a custom actionbar view, and as you can see in the screenshot below, there is a blank gray space in the actionbar. I want to remove it.
What have I done:
res/values-v11/styles.xml
<style name="AppBaseTheme" parent="#style/Theme.AppCompat.Light">
<item name="android:actionBarStyle">#style/ActionBarStyle</item>
<item name="actionBarStyle">#style/ActionBarStyle</item>
</style>
res/values/my_custom_actionbar.xml
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="ActionBarStyle" parent="#style/Widget.AppCompat.Light.ActionBar.Solid">
<item name="android:height">60dp</item>
</style>
</resources>
Manifest
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="19" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/AppName"
android:theme="#style/AppBaseTheme" >
<!-- activities... etc -->
</application>
MainActivity
public void onCreate(Bundle bundle) {
super.onCreate(bundle);
ActionBar actionbar = getSupportActionBar();
actionbar.setDefaultDisplayHomeAsUpEnabled(false);
actionbar.setDisplayHomeAsUpEnabled(false);
actionbar.setDisplayShowCustomEnabled(true);
actionbar.setDisplayShowHomeEnabled(false);
actionbar.setDisplayShowTitleEnabled(false);
actionbar.setDisplayUseLogoEnabled(false);
actionbar.setHomeButtonEnabled(false);
// Add the custom layout
View view = LayoutInflater.from(this).inflate(R.layout.actionbar, null, false);
actionbar.setCustomView(view);
}
I have found a recent post, that is pointing out that there is an issue with the latest release. I have also updated ADT and SDK to Android 5.
Android ActionBar's custom view not filling parent
I don't know what should I do.
Edit (partial solution):
Not working on Android <= API 10.
Android Lollipop, AppCompat ActionBar custom view doesn't take up whole screen width
What have I changed:
Use the latest sdk version:
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="21" />
Add a toolbarStyle:
<style name="AppBaseTheme" parent="#style/Theme.AppCompat.Light">
<item name="android:actionBarStyle">#style/ActionBarStyle</item>
<item name="actionBarStyle">#style/ActionBarStyle</item>
<item name="android:toolbarStyle">#style/ToolbarStyle</item>
<item name="toolbarStyle">#style/ToolbarStyle</item>
</style>
<style name="ToolbarStyle" parent="#style/Widget.AppCompat.Toolbar">
<item name="contentInsetStart">0dp</item>
<item name="android:contentInsetStart">0dp</item>
</style>

If you are adding the Toolbar via XML, you can simply add XML attributes to remove content insets.
<android.support.v7.widget.Toolbar
xmlns:app="schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/primaryColor"
android:contentInsetLeft="0dp"
android:contentInsetStart="0dp"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
android:contentInsetRight="0dp"
android:contentInsetEnd="0dp"
app:contentInsetRight="0dp"
app:contentInsetEnd="0dp" />

try this:
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
View customView = getLayoutInflater().inflate(R.layout.main_action_bar, null);
actionBar.setCustomView(customView);
Toolbar parent =(Toolbar) customView.getParent();
parent.setPadding(0,0,0,0);//for tab otherwise give space in tab
parent.setContentInsetsAbsolute(0,0);

The left inset is caused by Toolbar's contentInsetStart which by default is 16dp.
Change this to align to the keyline.
Update for support library v24.0.0:
To match the Material Design spec there's an additional attribute contentInsetStartWithNavigation which by default is 16dp. Change this if you also have a navigation icon.
It turned out that this is part of a new Material Design Specification introduced in version 24 of Design library.
https://material.google.com/patterns/navigation.html
However, it is possible to remove the extra space by adding the following property to Toolbar widget.
app:contentInsetStartWithNavigation="0dp"
Before :
After :

I found an other resolution (reference appcompat-v7 ) that change the toolbarStyle ,following code:
<item name="toolbarStyle">#style/Widget.Toolbar</item>
<style name="Widget.Toolbar" parent="#style/Widget.AppCompat.Toolbar">
<item name="contentInsetStart">0dp</item>
</style>

Just add app:contentInsetStart="0dp" to the XML attribute of the toolbar.

<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"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
android:paddingLeft="0dp">
This should be good enough.

Just Modify your styles.xml
<!-- ActionBar styles -->
<style name="MyActionBar" parent="Widget.AppCompat.ActionBar">
<item name="contentInsetStart">0dp</item>
<item name="contentInsetEnd">0dp</item>
</style>

Only add app:contentInsetStart="0dp" to the toolbar remove that left space.
So your Toolbar definition look like this
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
app:contentInsetStart="0dp"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
and it look like this

Instead of adding a toolbar in the layout, you can set your custom view as shown below.
Toolbar parent = (Toolbar) customView.getParent();
parent.setContentInsetsAbsolute(0,0);

If you check the documentation of toolbar, by default it has style defined and there is an item contentInsetStart.
<item name="contentInsetStart">16dp</item>
If you want to override this padding then it can be done in two ways.
1.Override the style and add your own style with contentInsetStart and contentInsetEnd values
<style name="MyActionBar" parent="Widget.AppCompat.ActionBar">
<item name="contentInsetStart">0dp</item>
<item name="contentInsetEnd">0dp</item>
</style>
2.In XML you can directly define the contentInsetStart and contentInsetEnd values
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
android:layout_height="?attr/actionBarSize">
<!--Add your views here-->
</androidx.appcompat.widget.Toolbar>

Using AppCompatAcitivty you can use just by
Toolbar mToolbar = (Toolbar) findViewById(R.id.toolbar);
View logo = getLayoutInflater().inflate(R.layout.custom_toolbar, null);
mToolbar.addView(logo, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
mToolbar.setContentInsetsAbsolute(0,0);

You need to add this line app2:contentInsetStart="0dp" in your toolbar
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app2="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
app2:contentInsetStart="0dp"/>

this work for me
toolbar.setPadding(0,0,0,0);
toolbar.setContentInsetsAbsolute(0,0);

Setting "contentInset..." attributes to 0 in the Toolbar didn't work for me. Nilesh Senta's solution to update the style worked!
styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="actionBarStyle">#style/Actionbar</item>
<item name="android:titleTextStyle">#style/ActionbarTitle</item>
</style>
<style name="Actionbar" parent="Widget.AppCompat.ActionBar">
<item name="contentInsetStart">0dp</item>
<item name="contentInsetEnd">0dp</item>
</style>
java (onCreate)
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayUseLogoEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);
ActionBar.LayoutParams layoutParams = new ActionBar.LayoutParams(
ActionBar.LayoutParams.MATCH_PARENT,
ActionBar.LayoutParams.MATCH_PARENT
);
View view = LayoutInflater.from(this).inflate(R.layout.actionbar_main, null);
actionBar.setCustomView(view, layoutParams);

In xml add these two attribute for Toolbar tag:
app:contentInsetEnd="0dp"
app:contentInsetStart="0dp"
and inside code add these lines:
// remove extra padding of toolbar
toolbar.setContentInsetsAbsolute(0, 0);
toolbar.setPadding(0, 0, 0, 0);
Tested on mobile and tablet devices both.

Kotlin
supportActionBar?.displayOptions = ActionBar.DISPLAY_SHOW_CUSTOM;
supportActionBar?.setCustomView(R.layout.actionbar);
val parent = supportActionBar?.customView?.parent as Toolbar
parent?.setPadding(0, 0, 0, 0)//for tab otherwise give space in tab
parent?.setContentInsetsAbsolute(0, 0)

I did not find a solution for my issue (first picture) anywhere, but at last I end up with a simplest solution after a few hours of digging. Please note that I tried with a lot of xml attributes like app:setInsetLeft="0dp", etc.. but none of them helped in this case.
Picture 1
the following code solved this issue as in the Picture 2
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//NOTE THAT: THE PART SOLVED THE PROBLEM.
android.support.design.widget.AppBarLayout abl = (AppBarLayout)
findViewById(R.id.app_bar_main_app_bar_layout);
abl.setPadding(0,0,0,0);
}
Picture 2

Create 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:id="#+id/menuToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0dp"
android:background="#color/white"
android:contentInsetLeft="10dp"
android:contentInsetRight="10dp"
android:contentInsetStart="10dp"
android:minHeight="?attr/actionBarSize"
android:padding="0dp"
app:contentInsetLeft="10dp"
app:contentInsetRight="10dp"
app:contentInsetStart="10dp"></android.support.v7.widget.Toolbar>
please follow this link for more - Android Tips

only adding android:padding="0dp" work for me
<android.support.v7.widget.Toolbar
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="60dp"
android:padding="0dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">

ActionBar ab = getSupportActionBar();
ab.setDisplayShowHomeEnabled(true);
ab.setDisplayShowCustomEnabled(true);
setDisplayShowTitleEnabled(true);
View customView = getLayoutInflater().inflate(R.layout.activity_main,null); //here activity_main.xml is the GUI design file.
ab.setCustomView(customView);
Toolbar parent =(Toolbar) customView.getParent(); //use V7 Toolbar import
parent.setContentInsetsAbsolute(0, 0);
setPadding(5,0,0,0);
ab.setIcon(R.mipmap.ic_launcher);

You can just use relative layout inside toolbar view group in your xml file and adjust the positions of widgets as you require them for your use case.No need to create custom layout & inflate it and attach to toolbar. Once done in your java code use setContentInsetsAbsolute(0,0) with your toolbar object before setting it as support action bar in your layout.

It would be better to add a background item into the style of the app actionbar to consistent with the background color of the customized actionbar:
<item name="android:background">#color/actionbar_bgcolor</item>
After android 6.0, the actionbar even has a margin-right space and cannot be set. Add a right margin adjusting in the activity like this: (the view is the customized actionbar or a right button in it)
int rightMargin = Build.VERSION.SDK_INT>=Build.VERSION_CODES.M ? 0 : 8; // may the same with actionbar leftMargin in px
ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) view.getLayoutParams();
p.setMargins(p.leftMargin, p.topMargin, rightMargin, p.bottomMargin);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1){
p.setMarginEnd(rightMargin);
}
view.setLayoutParams(p);
The actionbar machenism is just supported after Android 3.0+ app. If we use a toolbar (of support lib v7) instead, we should layout it in each xml of each activity, and take care of the issue of overlapping with system status bar in the Android 5.0 or later device.

Actionbar logo padding left

The actionbar shows a space on the left side of the logo. This space is reserved for the upindicator i think.
I want to give this space a defined distance of 20dp for example.
How can i do this?
I can set the padding of the icon to 0, but that does not remove the space between the logo and the left side of the screen.
I tried to solve it by using a custom layout. But there is a little problem. Every time the activity launches, first the normal actionbar appears and then shows the custom layout.
This is how i show my custom view:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_custom);
// Set up the action bar.
final ActionBar actionBar = getActionBar();
//set custom actionbar
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setCustomView(R.layout.actionbar);
//Displays the custom design in the actionbar
actionBar.setDisplayUseLogoEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
}
This is in my styles.xml:
<!--Customize the actionbar-->
<item name="android:windowActionBarOverlay">false</item>
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="android:actionButtonStyle">#style/MyActionButton</item>
</style>
<style name="MyActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#color/green2</item>
<item name="android:icon">#drawable/app_icon_small</item>
<!-- Support library compatibility -->
</style>
<style name="MyActionButton" parent="#android:style/Widget.Holo.Light.ActionButton">
<item name="android:paddingRight">#dimen/padding_border</item>
<item name="android:paddingLeft">#dimen/padding_border</item>
<item name="android:src">#drawable/icon_plus</item>
<!--<item name="android:minWidth">0dp</item>-->
<!--<item name="android:paddingLeft">0dp</item>-->
<!--<item name="android:paddingRight">15dp</item>-->
<!-- Support library compatibility -->
</style>
This is the layout of the custom view:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:background="#color/green2">
<ImageView
android:id="#+id/header"
android:contentDescription="#string/app_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="#dimen/padding_border"
android:paddingRight="#dimen/padding_border"
android:src="#drawable/app_icon_small"/>
<EditText
android:id="#+id/et_actionbar_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="YOLO"
android:gravity ="center"
android:textColor="#android:color/black"
android:textStyle="bold"
android:background="#android:color/transparent"
/>
</LinearLayout>

You can create xml file(your_xml_file) in folder /res/drawable, like this:
<?xml version="1.0" encoding="UTF-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:drawable="#drawable/menu_button"
android:right="20dp"/>
</layer-list>
and add it to code:
<activity android:name=...
android:logo="#drawable/your_xml_file" >

To reduce the space between the left side of the screen and the logo I used it:
<style name="AppTheme" parent="android:Theme.Holo">
<item name="android:actionBarStyle">#style/ActionBarStyle</item>
</style>
<style name="ActionBarStyle" parent="#android:style/Widget.Holo.ActionBar">
<item name="android:layout_marginLeft">-11dp</item>
</style>

Android ActionBar.Tab setCustomView() doesn't fill_parent

I'm using ActionBar.Tab setCustomView() method with this layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/background_grey" >
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="Test Tab"
android:textColor="#color/background_dark_green"/>
</RelativeLayout>
this is my function setting the ActionBar:
public void setActionBar()
{
ActionBar actionBar = getSupportActionBar();
//actionBar.hide();
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowTitleEnabled(false);
//set action bar navigation mode
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
//set tabs
//home tab
Tab tab = actionBar.newTab().setText(TAB_HOME).setTabListener(new PicoTabListener<StartFragment>(this, StartFragment.class));
tab.setCustomView(R.layout.tab_background);
actionBar.addTab(tab);
//events tab
tab = actionBar.newTab().setText(TAB_EVENTS).setTabListener(new PicoTabListener<EventsFragment>(this, EventsFragment.class));
actionBar.addTab(tab);
//enter event code
tab = actionBar.newTab().setText(TAB_CODE).setTabListener(new PicoTabListener<EnterCodeFragment>(this, EnterCodeFragment.class));
actionBar.addTab(tab);
}
and my activity layout:
<?xml version="1.0" encoding="utf-8"?>
<!-- This is the main layout of the application -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_basic_root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/background_dark_green" >
</RelativeLayout>
The results seams to look like this (The upper left tab with the gray background):
How can i make my custom view to fill whole tab and work properly ?
I'm using support package v7 for Android 2.3

Just ran into this myself and figured out the solution. You should create a style for the tabview that clears the background and the padding and use it in your theme.
styles.xml:
<style name="Custom.ActionBar.TabView.Empty" parent="#style/Widget.AppCompat.ActionBar.TabView">
<item name="android:background">#null</item>
<item name="android:padding">0dp</item>
</style>
themes.xml:
<style name="Theme.Custom" parent="#style/Theme.AppCompat.Light">
<item name="android:actionBarTabStyle">#style/Custom.ActionBar.TabView.Empty</item>
<item name="actionBarTabStyle">#style/Custom.ActionBar.TabView.Empty</item>
</style>

To every created tab object just add layoutParams:
..
tab.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));
actionBar.addTab(tab);

You have to rely on android:margin and android:padding when dealing with actionbarcompat's setCustomView
keeping in mind that it seems like the root element's padding, width, height, and margin, gets ignored.

If you're still having the issue, I found a way to get the whole space : ActionBar Tab with custom View not centered
