Why is it the worst? I tried to think how to implement each idea and I came across with these thoughts: 1) Idea #1: Imo, the movement/sliding effect will be less smooth, using canvas.drawText(). 2) Idea #2: Having a fixed-sized image has a limitation if the users continue rotating more than the image can handle. What happens if the image is already scrolled until the end side of 'W' or 'E' (from your example). 3) Idea #3: ... Thus, to solve the limitation in Idea #2, I am thinking to draw the panel on-the-fly based on the changed situation. Probably your concern is about the performance for re-drawing (?). Any better suggestion? 4) Idea #4: I am not sure what it is. Perhaps an extension of Idea #2?
