android set button background programmatically

Question

I would like to know how to set the button color programatically? I have coded the following but fails:

Button11.setBackgroundColor(R.color.red);
         


        

Answer 1

I have found that Android Studio gives me a warning that getColor() is deprecated when trying to do this:

Button11.setBackgroundColor(getResources().getColor(R.color.red))

So I found doing the method below to be the simple, up-to-date solution:

Button11.setBackgroundColor(ContextCompat.getColor(context, R.color.red))

You want to avoid hard-coding in the color argument, as it is considered bad code style.

Edit: After using setBackgroundColor() with my own button, I saw that the internal button padding expanded. I couldn't find any way of changing it back to having both height and width set to "wrap_content". Maybe its a bug.
