In my android application I want the standard/basic titlebar to change color.

To change the tekst color you have setTitleColor(int color), is there a way to change the background of the bar?

I suppose no. You can create titleless activity and create your own title bar in activity layout.

Check this, Line 63 and below... getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title_1); sets customview instead of default title view

How/where can I create a custom/own title bar?

Take a peek in platforms/android-2.1/data/res/layout/screen.xml of the SDK. It seems to define a title there. You can frequently examine layouts like this and borrow the style="?android:attr/windowTitleStyle" styles which you can then use and override in your own TextViews.

You may be able to even select the title for direct tweaking by doing:

TextView title(TextView) = findViewById(android.R.id.title);

Good answers above but is it possible to just color the title bar without having to create a custom layout for it?

This thread will get you started with building your own title bar in a xml file and using it in your activities

Edit

Here is a brief summary of the content of the link above - This is just to set the color of the text and the background of the title bar - no resizing, no buttons, just the simpliest sample

res/layout/mytitle.xml - This is the view that will represent the title bar

<?xml version="1.0" encoding="utf-8"?>
<TextView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/myTitle"
  android:text="This is my new title"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:textColor="@color/titletextcolor"
   />

res/values/themes.xml - We want to keep the default android theme and just need to change the background color of the title background. So we create a theme that inherits the default theme and set the background style to our own style.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="customTheme" parent="android:Theme"> 
        <item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground</item>   
    </style> 
</resources>

res/values/styles.xml - This is where we set the theme to use the color we want for the title background

<?xml version="1.0" encoding="utf-8"?>
<resources> 
   <style name="WindowTitleBackground">     
        <item name="android:background">@color/titlebackgroundcolor</item>                   
    </style>
</resources>

res/values/colors.xml - Set here the color you want

<?xml version="1.0" encoding="utf-8"?>
<resources>   
    <color name="titlebackgroundcolor">#3232CD</color>
    <color name="titletextcolor">#FFFF00</color>
</resources>

In the AndroidMANIFEST.xml, set the theme attribute either in the application (for the whole application) or in the activity (only this activity) tags

<activity android:name=".CustomTitleBar" android:theme="@style/customTheme" ...

From the Activity (called CustomTitleBar) :

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

        requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
        setContentView(R.layout.main);
        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.mytitle);

}

Most of the time just providing a link is a very cheap, and on stackoverflow not really liked answer. Try to get some of the knowledge from the link onto this page. You will get more and more knowledge in the community, and even if the link is down you answer still provides some search terms that can direct other people in the direction.

@Janusz : You are totally right - So I updated the post with the simpliest sample so that people can get started with instead of reading through the thread in the above link

See my answer below for use with a superclass to apply it to all children . (for ex : Activity->YourRootSuperClass->AnyOfYourActivity) Updates given in my post below would go in the YourRootSuperClass

After overwriting the android styling you don't need to add the custom title from code if you just want to change the background color
Janusz
As Janusz said, you don't need to have a custom View if you only want to override the used style (not adding new Views). In that case you also don't need to request a FEATURE_CUSTOM_STYLE. Finally, you can define the style a the application level to apply it to all your activities at once. Thanks for the code, by the way.

Thanks for this clear explanation, however I would like to add a bit more to your answer by asking a linked question (don't really want to do a new post as this one is the basement on my question).

I'm declaring my titlebar in a Superclass from which, all my other activities are children, to have to change the color of the bar only once. I would like to also add an icon and change the text in the bar. I have done some testing, and managed to change either one or the other but not both at the same time (using setFeatureDrawable and setTitle). The ideal solution would be of course to follow the explanation in the thread given in the link, but as i'm declaring in a superclass, i have an issue due to the layout in setContentView and the R.id.myCustomBar, because if i remember well i can call setContentView only once...

EDIT Found my answer :

For those who, like me, like to work with superclasses because it's great for getting a menu available everywhere in an app, it works the same here.

Just add this to your superclass:

requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
    setContentView(R.layout.customtitlebar);
    getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.customtitlebar);
    customTitleText = (TextView) findViewById(R.id.customtitlebar);

(you have to declare the textview as protected class variable)

And then the power of this is that, everywhere in you app (if for instance all your activities are children of this class), you just have to call

customTitleText.setText("Whatever you want in title");

and your titlebar will be edited.

The XML associated in my case is (R.layout.customtitlebar) :

<?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="fill_parent" android:background="@color/background">
<ImageView android:layout_width="25px" android:layout_height="25px"
    android:src="@drawable/icontitlebar"></ImageView>
<TextView android:id="@+id/customtitlebar"
    android:layout_width="wrap_content" android:layout_height="fill_parent"
    android:text="" android:textColor="@color/textcolor" android:textStyle="bold"
    android:background="@color/background" android:padding="3px" />
</LinearLayout>

Looks all right to me as well
