void handleUpEvent (KeyEvent event)
Handle key up event to stop tracking. This resets the dispatcher state, and updates the key event state based on it.
This is only needed if you are directly dispatching events, rather
than handling them in onKeyUp(int, KeyEvent).
| Parameters | |

event |
KeyEvent

boolean isTracking (KeyEvent event)
Return true if the key event is for a key code that is currently being tracked by the dispatcher.

void performedLongPress (KeyEvent event)
Keep track of the given event's key code as having performed an action with a long press, so no action should occur on the up.
This is only needed if you are directly dispatching events, rather
than handling them in onKeyLongPress(int, KeyEvent).

void reset (Object target)
Stop any tracking associated with this target.
| Parameters | |

void startTracking (KeyEvent event, Object target)
Start tracking the key code associated with the given event. This
can only be called on a key down. It will allow you to see any
long press associated with the key, and will result in
isTracking() return true on the long press and up
events.
This is only needed if you are directly dispatching events, rather
than handling them in onKeyDown(int, KeyEvent).
