RoadTrip is a sample application for Android that demonstrates how to implement several visual effects:
- Animated paths tracing
- Black & white to color conversion, used when scrolling a row of image to the left (the first image starts in B&W and turns into colors)
- Pinned scrolling, used to create a “stacked cards” effect when scrolling up and down the list
- Parallax scrolling, used to scroll the various maps at a different speed than other items
- Animated action bar opacity, as seen in Google Music
More detailed explanations can be found online.
Watch a video of the application running on a Moto X/Android 4.4.
