Andrioid Button set Background to Transparent Color

Question

How can I set the Background for a button to a transparent Color, like transparent Blue for eg, instead of a solid blue?

When I use button.setBackgroundColor(Color.BLUE) it sets it to a solid blue.

Thanks Chris

Answer 1

You could use Color.argb(). It takes four int parameters, each ranging from 0 to 255.

Let's say you want a blue button with 50% alpha:

button.setBackgroundColor(Color.argb(125, 0, 0, 255));
