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

You have to provide 3 or 4 states in your btn_defaut.xml as a selector.

1. Pressed state
2. Default state
3. Focus state
4. Enabled state (Disable state with false indication; see comments)

You will provide effect and background for the states accordingly.
