setting alpha value to ImageView
<p>I am using the following code to set the alpha value of an ImageView (this should be compatible with all devices, even pre API 11)</p>

<pre><code>AlphaAnimation alpha = new AlphaAnimation(0.85F, 0.85F);
alpha.setDuration(0); // Make animation instant
alpha.setFillAfter(true); // Tell it to persist after the animation ends
ImageView view = (ImageView) findViewById(R.id.transparentBackground);
view.startAnimation(alpha);
</code></pre>

<p>However, when I open the app on devices running on gingerbread and below, the imageView is completely transparent but on devices running on honeycomb or higher, the alpha value is set to .85 and the imageView is displayed perfectly.</p>

<p>How can make this happen on gingerBread as well?</p>
