Do not use unless you have a very good reason. All the elements that respond to press should have a visual feedback when touched. This is one of the primary reason a "web" app doesn't feel "native".
Called when the touch is released, but not if cancelled (e.g. by a scroll that steals the responder lock).
Delay in ms, from onPressIn, before onLongPress is called.
Delay in ms, from the start of the touch, before onPressIn is called.
Delay in ms, from the release of the touch, before onPressOut is called.
