get
Returns the current distance between the two pointers forming the gesture in progress.
Pointers are sorted by the time they were placed on the screen until lifted up. This means that index 0 will reflect the oldest added, still active pointer and index (getPointersCount - 1) will reflect the latest added, still active pointer.
The order of parameters is irrelevant.
Return
