Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

public void handleUpEvent (KeyEvent event)

Added in API level 5

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).

public boolean isTracking (KeyEvent event)

Added in API level 5

Return true if the key event is for a key code that is currently being tracked by the dispatcher.

public void performedLongPress (KeyEvent event)

Added in API level 5

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).

public void reset (Object target)

Added in API level 5

Stop any tracking associated with this target.

public void reset ()

Added in API level 5

Reset back to initial state.

public void startTracking (KeyEvent event, Object target)

Added in API level 5

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).
