Change Actionbar height on Android JellyBean

Question

I've been recently developing an Android app, in which i need to have a custom layout and dimension for the tab bar. The way that i did it until now is by using Jake Wharton's ActionBarSherlock library to support pre-HoneyComb Android versions, and by applying a style to the app in which i edit the actionBarSize style item.

Now, I've been testing the app on the Galaxy S3 (with Jellybean on it), and the tab bar height doesn't change anymore according to the actionBarSize value.

So I've started looking through JellyBean's code, and I found this method in the ActionBarPolicy class:

    public int getTabContainerHeight() {
            TypedArray a = mContext.obtainStyledAttributes(null, R.styleable.ActionBar,
               com.android.internal.R.attr.actionBarStyle, 0);
            int height = a.getLayoutDimension(R.styleable.ActionBar_height, 0);
            Resources r = mContext.getResources();
            if (!hasEmbeddedTabs()) {
                // Stacked tabs; limit the height
                height = Math.min(height,
                        r.getDimensionPixelSize(R.dimen.action_bar_stacked_max_height));
            }
            a.recycle();
            return height;
    }

From what i gather in this method, it seems that JellyBean limits the height of the TabBar, when the app is in portrait mode, by setting the tab bar height to the "action_bar_stacked_max_height" dimension value (which is 48dp, in 4.1's /values/dimen.xml file), even though I've set the action bar height in actionBarSize.

I've tried overriding this dimension value, by setting it to my own value in my own dimen.xml file, but i had no luck. It didn't work.

My question:

Do you guys know of a way in which i can override the"action_bar_stacked_max_height" dimen value?

Thank you in advance!

Try putting android:actionBarSize and actionBarSize under the Theme you are using, like so:

<style name="Theme.white_style" parent="@android:style/Theme.Holo.Light.DarkActionBar">
        <item name="android:actionBarSize">55dp</item>
        <item name="actionBarSize">55dp</item>
</style>
