Android: create circular image/menu item with picasso

Create Class CircleTransform.java

import com.squareup.picasso.Transformation;

public class CircleTransform implements Transformation {
    @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, source.getConfig());

        Canvas canvas = new Canvas(bitmap);
        Paint paint = new Paint();
        BitmapShader shader = new BitmapShader(squaredBitmap,
                BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);
        paint.setShader(shader);
        paint.setAntiAlias(true);

        float r = size / 2f;
        canvas.drawCircle(r, r, r, paint);

        squaredBitmap.recycle();
        return bitmap;
    }

    @Override
    public String key() {
        return "circle";
    }

public Bitmap getCroppedBitmap(Bitmap bitmap) {
    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
            bitmap.getHeight(), Bitmap.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(PorterDuff.Mode.SRC_IN));
    canvas.drawBitmap(bitmap, rect, rect, paint);
    //Bitmap _bmp = Bitmap.createScaledBitmap(output, 60, 60, false);
    //return _bmp;
    return output;
}

}

For image

Picasso.with(activity).load(mayorShipImageLink).transform(new CircleTransform()).into(ImageView);

For menu item

@Override
    public boolean onCreateOptionsMenu(final Menu menu) {
        this.menu = menu;
        getMenuInflater().inflate(R.menu.message_activity, menu);
        ActionBar actionBar = getSupportActionBar();
        actionBar.setDisplayHomeAsUpEnabled(true);
        actionBar.setElevation(0);
        
        String profile = "URLIMAGE.jpg"; 

        final Target mTarget = new Target() {
            @Override
            public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom loadedFrom) {
                Log.d("DEBUG", "onBitmapLoaded");
                BitmapDrawable mBitmapDrawable = new BitmapDrawable(getResources(), new CircleTransform().getCroppedBitmap(bitmap));
                menu.getItem(0).setIcon(mBitmapDrawable);
            }

            @Override
            public void onBitmapFailed(Drawable drawable) {
                Log.d("DEBUG", "onBitmapFailed");
            }

            @Override
            public void onPrepareLoad(Drawable drawable) {
                Log.d("DEBUG", "onPrepareLoad");
            }
        };

        Picasso.with(this)
                .load(profile)
                .into(mTarget);

        return super.onCreateOptionsMenu(menu);
    }
