changing ActionBar's height in orientation mode

问题

I have been using actionbar(android native) for a few days(jellybean 4.2). I tried to change the actionbar's height by adding such line in style.xml:

100dip

it works fine in landscapemode, but do not work in orientation mode.

in orientation mode, its height was not changed.

You just have to create dimensions for the height of the ActionBar in portrait and landscape mode:

values/dimens.xml:

<resources>
     <!-- dimension for the portrait ActionBar -->
     <dimen name="ab_height">100dp</dimen>
</resources>

values-land/dimens.xml:

<resources>
     <!-- dimension for the landscape ActionBar -->
     <dimen name="ab_height">120dp</dimen>
</resources>

Now you can use these dimensions like this:

<style [...]>
     <item name="android:actionBarSize">@dimen/ab_height</item>
</style>
