Parameters
layout SwipeDismissFrameLayout

onPreSwipeStart

boolean onPreSwipeStart (float xDown, 
                float yDown)

Notifies listeners that the view is now considering to start a dismiss gesture from a particular point on the screen.

Parameters
xDown float: The x coordinate of the initial ACTION_DOWN event for this motion.

yDown float: The y coordinate of the initial ACTION_DOWN event for this motion.

Returns
boolean true if this gesture should be recognized as a swipe to dismiss gesture, false otherwise.
