So I have a transition between 2 screens here.

When the user long presses anywhere on the map, that triggers a menu to animate into view from the left edge of the map, resulting in the screen shown on the right.

Well the problem I'm running into is, other places in this application prototype, I need to navigate to the screen shown at right, where the menu is already out, however, when I navigate to that screen, it re-runs the animation of the menu sliding into view again.  That needs to NOT happen.  So either the animations need to not fire after the initial firing, or I need to somehow transition to the second screen at the point AFTER the animations have occurred.

Do you have any ideas about the best way to approach that?

Thanks
