public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        DrawingView dv = new DrawingView(this);
        setContentView(dv);
    }

    class DrawingView extends View {
        Bitmap bitmap;

        public DrawingView(Context context) {
            super(context);
            bitmap = BitmapFactory.decodeResource(context.getResources(),
                    R.drawable.glossy_overlay);

        }

        @Override
        public void onDraw(Canvas canvas) {
            Paint paint = new Paint();
            // paint.setColor(Color.CYAN);
            canvas.drawBitmap(getclip(), 30, 20, paint);
        }

        public Bitmap getclip() {
            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;
        }
    }
}
