TextKeyListener

public class TextKeyListener
extends BaseKeyListener implements SpanWatcher

java.lang.Object
↳	android.text.method.MetaKeyKeyListener
	↳	android.text.method.BaseKeyListener
		↳	android.text.method.TextKeyListener

This is the key listener for typing normal text. It delegates to other key listeners appropriate to the current keyboard and language.

As for all implementations of KeyListener, this class is only concerned with hardware keyboards. Software input methods have no obligation to trigger the methods in this class.

`void`	`onSpanChanged(Spannable s, Object what, int start, int end, int st, int en)` This method is called to notify you that the specified object has been relocated from the range `ostart…oend` to the new range `nstart…nend` of the text.
`void`	`onSpanRemoved(Spannable s, Object what, int start, int end)` This method is called to notify you that the specified object has been detached from the specified range of the text.
`void`	`release()`
`static boolean`	`shouldCap(TextKeyListener.Capitalize cap, CharSequence cs, int off)` Returns whether it makes sense to automatically capitalize at the specified position in the specified text, with the specified rules.

`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.

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
