How can I change the android button to dark grey instead of light grey

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.

I have found this thread: Standard Android Button with a different color

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

button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0xFFAA0000));

I have tried

button.getBackground().setColorFilter(new LightingColorF开发者_如何转开发ilter(0xffffffff, 0xFF3A3A3A));

But all I get is a white color.

That's similar to what I am doing in my TabHost tabs in XML. If you have custom buttons and graphics it can be done in Java, but it is much easier if you're able to do it in your XML.

<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- When selected, use grey -->
    <item android:drawable="@drawable/settings"
          android:state_selected="true" />
    <!-- When not selected, use white-->
    <item android:drawable="@drawable/mountain" />
</selector>

You could use the default light theme
