Question

I’m using ActionBarSherlock and have applied a custom them to alter the appearance of the action bar:

<style name="Theme.MyTheme" parent="@style/Theme.Sherlock">
    <item name="android:actionBarStyle">@style/MyTheme.ActionBarStyle</item>
</style>

<style name="MyTheme.ActionBarStyle" parent="@style/Widget.Sherlock.ActionBar">
    <item name="android:background">@drawable/background_action_bar</item>
    <item name="android:icon">@drawable/image_action_bar_logo</item>
</style>

This works perfectly on a device running jelly bean but when I deploy it on an emulator running 2.2 or 2.3 the custom action bar style is ignored and the default style is used.

Any ideas?

Thanks
David

You have to adjust the theme and a little:

<style name="Theme.MyTheme" parent="@style/Theme.Sherlock">
    <!-- define the style for ActionBarSherlock -->
    <item name="actionBarStyle">@style/MyTheme.ActionBarStyle</item>

    <!-- define the style for native ActionBar for Android 4 and higher -->
    <item name="android:actionBarStyle">@style/MyTheme.ActionBarStyle</item>
</style>

Edit:

And also adjust the style appropriately:

<style name="MyTheme.ActionBarStyle" parent="@style/Widget.Sherlock.ActionBar">
    <!-- for ActionBarSherlock -->
    <item name="background">@drawable/background_action_bar</item>
    <item name="icon">@drawable/image_action_bar_logo</item>

    <!-- for native ActionBar for Android 4 and higher -->
    <item name="android:background">@drawable/background_action_bar</item>
    <item name="android:icon">@drawable/image_action_bar_logo</item>
</style>
