Question

I am working on painting line, I faced a basic problem with changing the color :S:S

I have the following code, I got an error in the last line of code I cant add argument to new Color(???) >> I cant add the R, G, B color numbers

        Paint paint = new Paint();
        Random random = new Random();
        int R = (int)(Math.random()*256);
        int G = (int)(Math.random()*256);
        int B= (int)(Math.random()*256);
        paint.setColor(new Color(R , G , B));

Answer 1

You can’t create a Color object like that. Color is just a static Android helper class that handles color-based operations.

Try this:

paint.setColor(Color.rgb(R , G , B));

For reference, see the Color.rgb(...) method.
