After long brainstorming I have found the solution

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.drawRoundRect(rectF, roundPx, roundPx, paint);    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);    //Bitmap _bmp = Bitmap.createScaledBitmap(output, 60, 60, false);    //return _bmp;    return output;}

to generate Circle from rectangles

public static Bitmap getCircularBitmap(Bitmap bitmap) {    Bitmap output;    if (bitmap.getWidth() > bitmap.getHeight()) {        output = Bitmap.createBitmap(bitmap.getHeight(), bitmap.getHeight(), Config.ARGB_8888);    } else {        output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getWidth(), 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());    float r = 0;    if (bitmap.getWidth() > bitmap.getHeight()) {        r = bitmap.getHeight() / 2;    } else {        r = bitmap.getWidth() / 2;    }    paint.setAntiAlias(true);    canvas.drawARGB(0, 0, 0, 0);    paint.setColor(color);    canvas.drawCircle(r, r, r, paint);    paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));    canvas.drawBitmap(bitmap, rect, rect, paint);    return output;}

You Can make your imageview circular using RoundedBitmapDrawable

here is the code for achieving roundedImageview:

ImageView profilePic=(ImageView)findViewById(R.id.user_image);//get bitmap of the imageBitmap imageBitmap=BitmapFactory.decodeResource(getResources(),  R.drawable.large_icon);RoundedBitmapDrawable roundedBitmapDrawable=RoundedBitmapDrawableFactory.create(getResources(), imageBitmap);//setting radiusroundedBitmapDrawable.setCornerRadius(50.0f);roundedBitmapDrawable.setAntiAlias(true);profilePic.setImageDrawable(roundedBitmapDrawable);
