setting ImageButton's background transparent with Theme.Light in android
<p><strong>How to set the background color of an ImageButton 'transparent' ?</strong></p>

<p>The following piece of code works when I try it with default android theme, but with 'Theme.Light', I see a gray background.</p>

<pre><code>ImageButton deleteBtn = new ImageButton( this );
deleteBtn.setImageResource( R.drawable.delete_big );
deleteBtn.setBackgroundColor(android.R.color.transparent);
</code></pre>

<p>(I need to dynamically create these buttons.. I have seen solutions which mention specifying @null background color using android's layout.xml files. How can I achieve the same thing programmatically ? Any help highly appreciated. Thanks!</p>
