RoundedShape ImageView

In a modern android application, user or profile pictures are shown in a rounded shape and those images filled out with the aspect ratio.

Use the below code to achieve that.

public static Bitmap getRoundedShape(Bitmap scaleBitmapImage) {
        int targetWidth = 50;
        int targetHeight = 50;
        Bitmap targetBitmap = Bitmap.createBitmap(targetWidth,
                targetHeight,Bitmap.Config.ARGB_8888);

        Canvas canvas = new Canvas(targetBitmap);
        Path path = new Path();
        path.addCircle(((float) targetWidth - 1) / 2,
                ((float) targetHeight - 1) / 2,
                (Math.min(((float) targetWidth),
                        ((float) targetHeight)) / 2),
                Path.Direction.CCW);

        canvas.clipPath(path);
        Bitmap sourceBitmap = scaleBitmapImage;
        canvas.drawBitmap(sourceBitmap,
                new Rect(0, 0, sourceBitmap.getWidth(),
                        sourceBitmap.getHeight()),
                new Rect(0, 0, targetWidth, targetHeight), null);
        return targetBitmap;
    }

Done!
