How to automatically adjust the font size in the toolbar of the action bar based on orientation?

I wanted to place the spinner in the action bar, as in the Gmail application. So I created the following layout.

  <?xml version="1.0" encoding="utf-8" ?> 
  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 android:orientation="vertical"
 android:layout_width="match_parent"
 android:layout_height="match_parent">
  <TextView android:id="@+id/spinner_list_item_selected_header" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_gravity="center" 
android:textStyle="bold" 
android:gravity="center" 
android:text="Sales" /> 
      <TextView android:id="@+id/spinner_list_item_selected_text"  android:layout_width="match_parent"
android:layout_height="wrap_content" 
android:layout_gravity="center" 
android:textStyle="bold" 
android:gravity="center" 
android:text="" /> 
      </LinearLayout>

This counter is then loaded into the header line using the following code:

getActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
getActionBar().setListNavigationCallbacks(mSpinnerAdapter, mOnNavigationListener);

It works as expected, except in landscape mode the text is not suitable. In Gmail, the font size is reduced. Is there a way to automatically adjust the font size based on orientation?

// you need to use the dimensions.xml in the values ​​folder

<!-- Text size for action bar titles -->
    <dimen name="action_bar_title_text_size">18dp</dimen>
    <!-- Text size for action bar subtitles -->
    <dimen name="action_bar_subtitle_text_size">14dp</dimen>
    <!-- Top margin for action bar subtitles -->
    <dimen name="action_bar_subtitle_top_margin">-3dp</dimen>
    <!-- Bottom margin for action bar subtitles -->
    <dimen name="action_bar_subtitle_bottom_margin">5dip</dimen>

create another folder with values ​​- earth

in fact that is.xml

 <!-- Text size for action bar titles -->
    <dimen name="action_bar_title_text_size">16dp</dimen>
    <!-- Text size for action bar subtitles -->
    <dimen name="action_bar_subtitle_text_size">12dp</dimen>
    <!-- Top margin for action bar subtitles -->
    <dimen name="action_bar_subtitle_top_margin">-2dp</dimen>
    <!-- Bottom margin for action bar subtitles -->
    <dimen name="action_bar_subtitle_bottom_margin">4dip</dimen>
