How to make title bar progress bar a spin progress bar istead of horizontal bar?
<p>I have created a activity and set a the title bar to contain a progress bar like this:</p>

<pre><code>this.requestWindowFeature(Window.FEATURE_PROGRESS);
getWindow().setFeatureInt(Window.FEATURE_PROGRESS, 500);
</code></pre>

<p>But it turns out to be a horizontal bar, how can I make this a spin bar? (without creating a custom title bar)</p>

<p>Thanks, Jason</p>
