Draw circle shape in canvas is very easy thing to do if you are familiar with Canvas in Android. Please checkout this tutorial if you don’t know about how to create basic Canvas, display it to ImageView and save it as Bitmap.
Here we draw one canvas of 500×500 resolution and draw circle shape in the middle of the canvas.
The below line will draw circle shape in canvas.
canvas.drawCircle(x, y, radius, paint);
Here we pass x and y as the center coordinats of the circle. radius represents the radius of the circle being drawn. And paint is the Paint for drawing circle.

Paint pBackground = new Paint(); pBackground.setColor(Color.WHITE); canvas.drawRect(0, 0, 512, 512, pBackground); Paint pCircle = new Paint(); pCircle.setColor(Color.BLACK); canvas.drawCircle(256, 256, 256, pCircle);
