Android: Showing indeterminate progress bar in TabHost activity
<p>I know that the following code should show and hide a tiny circular progress bar with the following code in Android:</p>

<pre><code>requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setProgressBarIndeterminateVisibility(true);
setProgressBarIndeterminateVisibility(false);
</code></pre>

<p>The problem is that I am using a TabHost and I need to be able to do this from one of the "child" activities. Is there any way I can go about doing this?</p>

<p>I found <a href="http://www.mail-archive.com/android-developers@googlegroups.com/msg18609.html" rel="nofollow">this question</a> on the intarwebs but as you can see, it went unanswered.</p>
