    copied!<p>I'd like to qualify with "I have not checked this using ActionBarSherlock only the standard actionbar"</p> <p>That said I know this will work on the standard actionbar and see no reason why it would not in ActionBarSherlock.</p> <p>In the onCreate of the activity I have (I'm using the logo attribute but it will work for MenuItems as well)</p> <pre><code> getActionBar().setLogo(R.drawable.logo); getActionBar().setDisplayUseLogoEnabled(true); getActionBar().setHomeButtonEnabled(true); </code></pre> <p>In logo.xml I have a selector</p> <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;item android:state_pressed="true" android:drawable="@drawable/logopressed"/&gt; &lt;item android:drawable="@drawable/logonotpressed" /&gt; &lt;/selector&gt; </code></pre> <p>In logopressed.xml A layer list can be used to make the background</p> <pre><code>&lt;layer-list xmlns:android="http://schemas.android.com/apk/res/android" &gt; &lt;item android:drawable="@android:color/holo_purple" /&gt; &lt;item android:drawable="@drawable/logo_normal" /&gt; &lt;/layer-list&gt; </code></pre> <p>In logonotpressed.xml switch out the background colour and/or icon drawable as desired</p> <pre><code>&lt;layer-list xmlns:android="http://schemas.android.com/apk/res/android" &gt; &lt;item android:drawable="@android:color/white" /&gt; &lt;item android:drawable="@drawable/logo_inverted" /&gt; &lt;/layer-list&gt; </code></pre> <p>So the crux of this solution is to set the selector drawable and let it select a whole new drawable for each state rather than setting a selector drawable to the background attribute of a otherwise static variable</p> <p>Note: you should be able to theme the items with a background instead of doing 2 layers but I haven't been able to get this to work</p>
