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

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

May be this question can help you a bit.

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

Try this.

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!

its simplest way ((Button)findViewById(R.id.yourButtonResId)).setBackground(#ffffff);
