You can use the PorterDuff.Mode enum with its properties.

((Button)findViewById(R.id.yourButtonResId)).getBackground().setColorFilter(0xFF00FF00, PorterDuff.Mode.MULTIPLY);

Here's the result containing an unchanged default Pass button and a Submit button on which I applied the line above:

To Google travelers, if this is a Drawable update (e.g. you are going to update your button that already have a drawable, such as button.getBackground.doStuff()) you need to use Button.invalidateSelf().

public void invalidateSelf()

You can use button.setBackgroundColor(Color.BLUE); BLUE can be replaced by the color you want if its available!

May be this question can help you a bit.

In a nutshell you have to use this.getResources().getColor(R.color.orange) in argument.

**EDIT: ** Pasted a wrong code. Edited

Try this.
