Option menu style change on change of style of activity in manifest
<p>Initially in the manifest when i don't set any theme inside the activity tag my option menu look like this which is default..</p>

<p>But once i set this theme <code>android:theme="@android:style/Theme.NoTitleBar"</code>  in the activity tag of my manifest file the option menu style changes.</p>

<p>Screen shots after adding <code>android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen"</code></p>
