Background color

Hi, I am trying to change background color in app. It works fine with pre-set colors:

relativeLayout.setBackgroundColor(Color.WHITE);

But when I want to change it into custom RGB color it gives an error stating that below data should be as "int" value:

relativeLayout.setBackgroundColor(78,238,148);

How to fix this?

Thanks.

The setBackgroundColor() method you are calling only takes a single Integer value, whereas you are passing three. See the documentation for more information.

To use RGB values, try using the Color class..

Something like this may work (untested):

relativeLayout.setBackgroundColor(Color.rgb(78,238,148));
