How to grey out a button?

Question

I have a button defined as shown below. When I want to disable it I use my_btn.setEnabled(false), but I would also like to grey it out. How can I do that?

Answer 1

The most easy solution is to set color filter to the background image of a button as I saw here

You can do as follow:

if ('need to set button disable')
    button.getBackground().setColorFilter(Color.GRAY, PorterDuff.Mode.MULTIPLY);
else
    button.getBackground().setColorFilter(null);

Hope I helped someone...
