Button.setEnabled(false) does not make the button grey

Question

I have a Button in my application. When I use setEnabled(false) on it, it turns grey. However if I first modify the background of the Button and then call setEnabled(false) on it, it does not turn grey (but the Button is not enabled). Why is that and how can I make it grey whatever happens to it?

Answer 1

In my opinion, the easiest solution would be to set the background of the button in your activity. Like the following:

button.setAlpha(.5f);
button.setClickable(false);

.5f alpha is equivalent to grey disable button. It's often useful if the background of your button is an image.
