I am using Piccaso library for circular image but somehow i am not able to add red circular border aound image. I am using below Tranform class to do it:
ublic class RedCircleTransform implements Transformation {
        int mBorderSize;
        @Override
        public Bitmap transform(Bitmap source) {
            int size = Math.min(source.getWidth(), source.getHeight());
            int x = (source.getWidth() - size) / 2;
            int y = (source.getHeight() - size) / 2;
            Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);
            if (squaredBitmap != source) {
                source.recycle();
            }
            Bitmap bitmap = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);
            Canvas canvas = new Canvas(bitmap);
            Paint paint = new Paint();
            BitmapShader shader = new BitmapShader(squaredBitmap,
                    BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);
            paint.setShader(shader);
        paint.setStrokeWidth(10);
            paint.setColor(Color.RED);
            paint.setAntiAlias(true);
            float r = size / 2f;
            canvas.drawCircle(r, r, r, paint);
            squaredBitmap.recycle();
            return bitmap;
        }
        @Override
        public String key() {
            return "circle";
        }
}
