2. android spinning image

hi,

i am trying to create two spinning wheels, as in pulleys, so everytime
the attached rope moves, the two pulleys will rotate.  i have tried
two approaches:

1) use Matrix.postRotate within the onDraw() method of the View class,
which calls the following:

        private void drawSpinningWheel(Canvas canvas)
        {
                try
                {
                        canvas.save();

                Bitmap bitmapOrg = null;

                int iDrawable = R.drawable.spinning_button;

                bitmapOrg = BitmapFactory.decodeResource(getResources(),
iDrawable);

            if(bitmapOrg != null)
            {
                    int width = bitmapOrg.getWidth();
                    int height = bitmapOrg.getHeight();
                    int newWidth = 24;
                    int newHeight = 24;

                    // calculate the scale - in this case = 0.4f
                    float scaleWidth = ((float) newWidth) / width;
                    float scaleHeight = ((float) newHeight) / height;

                    // createa matrix for the manipulation
                    Matrix matrix = new Matrix();
                    // resize the bit map
                    matrix.postScale(scaleWidth, scaleHeight);
                    matrix.postRotate((float) mDegrees++);

                        Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 
0, 0,
                            width, height, matrix, true);

                        canvas.drawBitmap(resizedBitmap, matrix, null);

            }

                        canvas.restore();
                }
                catch(Exception e)
                {
                        Log.e(TAG + "drawSpinningWheel", e.getMessage());
                }

        }

but it seems like the image not only spins but rotates around another
axis

2) use SurfaceView and a separate thread, in the run() call this:

        private void doDraw(Canvas canvas) {
            // Draw the background image. Operations on the Canvas
accumulate
            // so this is like clearing the screen.
            canvas.drawBitmap(mBackgroundImage, 0, 0, null);

            int yTop = mCanvasHeight - ((int) mY +
mSpinningWheelImageHeight / 2);
            int xLeft = (int) mX - mSpinningWheelImageWidth / 2;

...

            // Draw the ship with its current rotation
            canvas.save();
            canvas.rotate((float) mHeading++, (float) mX,
mCanvasHeight
                    - (float) mY);

                mSpinningWheelImage.setBounds(xLeft, yTop, xLeft +
mSpinningWheelImageWidth, yTop
                        + mSpinningWheelImageHeight);
                mSpinningWheelImage.draw(canvas);


            canvas.restore();
        }

i get the spinning to work but i can't add another spinning wheel.  i
even tried to create another thread for the second spinning wheel,
only one shows up.  can someone point me in the right direction?
thanks.
