title: Native ActionBar selectableItemBackground with ActionBarSherlock
body: <p>I try to change the background of an selected item in the ActionBar. I use ActionBarSherlock to be compatible with older Android Versions. I set a specific theme to my Activity when the App runs on a device with ICS.</p>
  
  <p>This is my current style:</p>
  
  <pre><code>&lt;style name="Theme.Custom.Light" parent="@android:style/Theme.Holo.Light.DarkActionBar"&gt;
      &lt;item name="android:actionBarItemBackground"&gt;@drawable/abs__item_background_holo_dark&lt;/item&gt;
      &lt;item name="android:selectableItemBackground"&gt;@drawable/abs__item_background_holo_dark&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>My drawable looks like this:</p>
  
  <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"
        android:exitFadeDuration="@android:integer/config_mediumAnimTime"&gt;
      &lt;item android:state_focused="true"  android:state_enabled="false" android:state_pressed="true" android:drawable="@drawable/abs__list_selector_disabled_holo_dark" /&gt;
      &lt;item android:state_focused="true"  android:state_enabled="false"                              android:drawable="@drawable/abs__list_selector_disabled_holo_dark" /&gt;
      &lt;item android:state_focused="true"                                android:state_pressed="true" android:drawable="@drawable/abs__list_selector_background_transition_holo_dark" /&gt;
      &lt;item android:state_focused="false"                               android:state_pressed="true" android:drawable="@drawable/abs__list_selector_background_transition_holo_dark" /&gt;
      &lt;item android:state_focused="true"                                                             android:drawable="@drawable/abs__list_focused_holo" /&gt;
      &lt;item                                                                                          android:drawable="@android:color/transparent" /&gt;
  &lt;/selector&gt;
  </code></pre>
  
  <p>It seems to be that the attribute would not be overrided. What do I wrong?</p>
