title: Change background, textcolor of AlertDialog
body: <p>I try to change  <b>background</b> and <b>textcolor</b> of AlertDialog. <br />
  But I can change only color of title with <code>android:windowTitleStyle</code> <br /> <br />
  Activity: <br />
  <code>AlertDialog.Builder adb = new AlertDialog.Builder(new ContextThemeWrapper(this,  R.style.AlertDialogCustom)); <br />
  </code> <br /></p>
  
  <p>styles.xml <br /></p>
  
  <p><code>style name="AlertDialogCustom" parent="Holo.Theme.Sherlock"                   </p>
  
  <p></code> <br/> 
  How can I do that? Thanks.</p>
