title: How to change the background colour of the action bar
body: <p>I want to change the background colour of the action bar and maybe the text colour too. This question has already asked <a href="https://stackoverflow.com/questions/8024706/how-do-i-change-the-background-color-of-the-actionbar-of-an-actionbaractivity-us">here</a> but I do not understand it.
   Do I need to make a new xml file with this:</p>
  
  <pre><code> &lt;resources&gt;
      &lt;style name="MyTheme" parent="@android:style/Theme.Holo.Light"&gt;
          &lt;item name="android:actionBarStyle"&gt;@style/MyActionBar&lt;/item&gt;
      &lt;/style&gt;
  
      &lt;style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar"&gt;
          &lt;item name="android:background"&gt;ANY_HEX_COLOR_CODE&lt;/item&gt;
      &lt;/style&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>And where should I save it? what folder?
  and how to set this as my theme?</p>
  
  <p>Thanks in advance.</p>
