how to create a circular image in android… as google+ is using

Question

I am trying to create a circular image, by putting a circular transparent image over it...
But I want to create the circular image as in Google+, is there any other way, without using canvas?

Bitmap circleBitmap = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
                                BitmapShader shader = new BitmapShader (bitmap,  TileMode.CLAMP, TileMode.CLAMP);
                                Paint paint = new Paint();
                                    paint.setShader(shader);
                                    paint.setAntiAlias(true);
                                    paint.setFilterBitmap(true);
                                    paint.setDither(true);      
                                    paint.setColor(Color.parseColor("#BAB399"));
                                Canvas c = new Canvas(circleBitmap);
                                c.drawCircle(bitmap.getWidth()/2, bitmap.getHeight()/2, bitmap.getWidth()/2, paint);
                                img.setImageBitmap(circleBitmap);

public Bitmap getCroppedBitmap(Bitmap bitmap) {
    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
            bitmap.getHeight(), Config.ARGB_8888);
    Canvas canvas = new Canvas(output);    
    final int color = 0xff424242;
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());    
    paint.setAntiAlias(true);
    canvas.drawARGB(0, 0, 0, 0);
    paint.setColor(color);
    canvas.drawCircle(bitmap.getWidth() / 2, bitmap.getHeight() / 2,
            bitmap.getWidth() / 2, paint);
    paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
    canvas.drawBitmap(bitmap, rect, rect, paint);
    return output;
} 

or use a mask that have into the center a transparent circle

In android.support.v4 a new class is introduced for creating circular image or rounded cornered image. Which is RoundedBitmapDrawable there's no need to use customized methods.To set any image as round cornered or circular follow the below syntax.

RoundedBitmapDrawable roundedBitmapDrawable = RoundedBitmapDrawableFactory.create(mContext.getResources(), bitmap);
roundedBitmapDrawable.setCornerRadius(pixels);
imageView.setImageDrawable(roundedBitmapDrawable);

It's that simple. Source
