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

Using setBackgroundColor() affects the style. So, declare a new style of the same properties with respect to the previous button, with a a different color.

Now, use OnClick method.

location.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            location.setBackgroundResource(R.drawable.green);

        }
    });

this changes the button but looks similar to changing the background.
