Tween animation on a Canvas in a custom View

Programmer Question

I have a class that extends View and I draw everything I need inside it's canvas in the onDraw method. Something like this:

protected void onDraw(Canvas canvas) {
        synchronized (this) {
                float h = mHeight;
                float w = mWidth;

                canvas.drawColor(Color.WHITE);

                float roadLine= (85.0f/100.0f)*h;

                canvas.drawBitmap(mTop, 0, roadLine-mTop.getHeight(), null);

                //this is what I'd like to animate
                canvas.drawBitmap(mSmoke);

        }
    }

Now, how do I make an Animation (tween animation) draw in here?
