Android Button Styling Programmatically

Question

How do you programmatically add/remove style to an android button? Is it possible to apply the styling at runtime?

I have two buttons that look like these

Answer 1

You can't apply xml-defined styles in runtime (from code). If you want to change background and font style when button is clicked (pressed) you should create selector which defines what background to use for normal button or for clicked state.

If selector is not what you want, you should manually set every button property to desired value via button's setXXX method of Button class.

P.S. You can swap old button for a new another one inflated from xml with different style. But this is not a good way I suppose...
