Inherited Methods

From class android.text.method.MetaKeyKeyListener

static void	adjustMetaAfterKeypress(Spannable content) Call this method after you handle a keypress so that the meta state will be reset to unshifted (if it is not still down) or primed to be reset to unshifted (once it is released).
static long	adjustMetaAfterKeypress(long state) Call this method after you handle a keypress so that the meta state will be reset to unshifted (if it is not still down) or primed to be reset to unshifted (once it is released).
void	clearMetaKeyState(View view, Editable content, int states)
long	clearMetaKeyState(long state, int which)
static void	clearMetaKeyState(Editable content, int states)
final static int	getMetaState(long state) Gets the state of the meta keys.
final static int	getMetaState(CharSequence text) Gets the state of the meta keys.
final static int	getMetaState(CharSequence text, int meta) Gets the state of a particular meta key.
final static int	getMetaState(long state, int meta) Gets the state of a particular meta key.
static long	handleKeyDown(long state, int keyCode, KeyEvent event) Handles presses of the meta keys.
static long	handleKeyUp(long state, int keyCode, KeyEvent event) Handles release of the meta keys.
static boolean	isMetaTracker(CharSequence text, Object what) Returns true if this object is one that this class would use to keep track of any meta state in the specified text.
static boolean	isSelectingMetaTracker(CharSequence text, Object what) Returns true if this object is one that this class would use to keep track of the selecting meta state in the specified text.
boolean	onKeyDown(View view, Editable content, int keyCode, KeyEvent event) Handles presses of the meta keys.
boolean	onKeyUp(View view, Editable content, int keyCode, KeyEvent event) Handles release of the meta keys.
static long	resetLockedMeta(long state) Call this if you are a method that ignores the locked meta state (arrow keys, for example) and you handle a key.
static void	resetLockedMeta(Spannable content) Call this if you are a method that ignores the locked meta state (arrow keys, for example) and you handle a key.
static void	resetMetaState(Spannable text) Resets all meta state to inactive.

void	finalize() Is called before the object's memory is being reclaimed by the VM.
final Class<? extends Object>	getClass() Returns the unique instance of Class which 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(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.
