                GradientDrawable grad = new GradientDrawable(Orientation.TOP_BOTTOM,color);
 
                grad.setSize(100,200);
 
                grad.setColor(R.color.green);           
 
                grad.setBounds(0, 0, 100, 200);

Btw, what's your canvas? Button? Image? Or else?

Hello sasuke,

what is wrong with your code, does it show only green :?:

Try simplifying your code. First remove this line:

Using java Syntax Highlighting

          grad.setColor(R.color.green);

Hello all,

@tum0rc0re, thank you. it's works now..

I made a class that extends the View (for handling the main menu)...

@plusminus, the problem is, it's not showing anything...

Using java Syntax Highlighting

        @Override
        protected void onDraw(Canvas canvas) {
                drawMenu();             
                int color[] = new int[2];
                color[0] = R.color.green;
                color[1] = R.color.yellow;
                GradientDrawable grad = new GradientDrawable(Orientation.TOP_BOTTOM,color);
                grad.setSize(100,200);  
                grad.setBounds(0, 0, 100, 200);
                grad.draw(canvas);
                Paint pt = new Paint();
                canvas.drawBitmap(bmp, 0, 0, pt);
        }
 
Parsed in 0.036 seconds,  using GeSHi 1.0.8.4

the drawMenu method works great, but the gradient won't appear on the canvas..

Regards,
sasuke
