How to draw Circle on Empty Canvas?

I wants to draw Circle on empty canvas, but not getting how to do. This is code I'm using to create Empty canvas inside my custom ImageView class.

bmpBase = Bitmap.createBitmap(image_width, image_height, Bitmap.Config.ARGB_8888);
canvas = new Canvas(bmpBase);
Paint paint = new Paint();
paint.setColor(Color.BLUE);
canvas.drawCircle(100, 100, 30, paint);

try this, in your MainActivity first find your imageView and then:

                drawingImageView = (ImageView)findViewById(R.id.DrawingImageView);
                Paint paint = new Paint();
                paint.setColor(Color.BLUE));
                paint.setStyle(Paint.Style.STROKE);
                paint.setStrokeWidth(15);    
                bmpBase = Bitmap.createBitmap(image_width, image_height, Bitmap.Config.ARGB_8888);
                Canvas canvas = new Canvas(bitmap);
                canvas.drawCircle(100, 100, 30, paint);
                drawingImageView.setImageBitmap(bitmap);

Try this:

You need to set the Paint style to stroke if you just want an outline with no fill:

Paint p = new Paint();
p.setStyle(Paint.Style.STROKE);

and if you want filled circle then:

Paint p = new Paint();
p.setStyle(Paint.Style.FILL);

Or you can refer this: http://android-coding.blogspot.in/2012/04/draw-circle-on-canvas-canvasdrawcirclet.html
