How can I change the android button to dark grey instead of light grey
<p>I would like to change the color of the android button in my application to be dark grey instead of light grey. I intent to keep the color of the focus/pressed the same. I just want to change the color of the button in 'normal' state to dark grey.</p>

<p>I have found this thread:
<a href="http://stackoverflow.com/questions/1521640/standard-android-button-with-a-different-color">Standard Android Button with a different color</a></p>

<p>I think the easiest way is to do this. Is that correct? But how can I make the LightingColor Filter to make it darkgrey?</p>

<pre><code>button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0xFFAA0000));
</code></pre>

<p>I have tried</p>

<pre><code>button.getBackground().setColorFilter(new LightingColorFilter(0xffffffff, 0xFF3A3A3A));
</code></pre>

<p>But all I get is a white color.</p>
