I am trying to come up with a UI similar to the directions screen from Google Maps. I can position the Source and Destination text boxes correctly. But what about the blue icon on the left of "My Location"? It extends vertically downwards to an empty circle that ends at the left of the destination text box.
Could it be one single image from blue icon to gray icon? But shouldn't it resize properly, based on the height of the source and destination text boxes?
