Android: Change actionbar style

I am currently trying to change the style of my action bar to accomplish the following:

In order to do so, this is what I have tried:

Manifest file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.shoppinglist"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppThemeWithoutActionBarTitle">
        <activity
            android:name="com.example.shoppinglist.MainActivity"
            android:label="@string/app_name"
            android:logo="@drawable/mylogo">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

And in styles.xml:

<resources>

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style name="AppBaseTheme" parent="android:Theme.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
<item name="android:actionBarStyle">@style/ActionBar</item>
    </style>

    <style name="ActionBar" parent="android:Widget.Holo.Light.ActionBar.Solid.Inverse">
    <item name="android:background">#ffffff</item>
</style>

    <style name="ActionBarWithoutTitle" parent="@style/ActionBar">
    <item name="android:displayOptions">useLogo</item>
</style>

    <style name="AppThemeWithoutActionBarTitle" parent="AppTheme">
    <item name="android:actionBarStyle">@style/ActionBarWithoutTitle</item>
</style>

</resources>

However, when I tried this, everything worked except for replacing the app logo: instead of the new logo @drawable/mylogo, no logo appears at all. How can I fix this?

You are close to the right answer. All you need is to modify one element in your styles.xml file to the following:

<style name="ActionBarWithoutTitle" parent="@style/ActionBar">
    <item name="android:displayOptions">showHome|useLogo</item>
</style>

The addition of showHome| will allow for the logo you need to be present.

You need to set in your Activity whether you want to use the launcher icon or the logo icon. So add this line to your Activity in onCreate:

setDisplayUseLogoEnabled(true);

Also your approach can be done programatically as well:

getActionBar().setTitle("");
getActionBar().setLogo(R.drawable.my_logo);
getActionBar().setBackgroundDrawable(getResources().getDrawable(R.drawable.my_background_drawable));

This would of course be a good solution, if you wanted to add different styles to different Activities, but would be a bit cumbersome, if you have more Activities and wanted the same style all over.
