Transparent blurry view which blurs layout underneath
<p>I've got a Linearlayout which I've made transparent, and now I'm looking for a way to give it a Blur effect, so what's ever underneath it gets blurry. Just like the Windows 7 Aero look (see screenshot).</p>

<p>I know you can do a blur effect like this:</p>

<pre><code>getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
</code></pre>

<p>But this only applies to like blurring the background when a dialog appears.</p>

<p>I've been googling for almost an hour, and I can't find anything. Does anyone have any suggestions on how to do this? </p>

<p>Thanks</p>
