* Object used to report key and button events.
* Each key press is described by a sequence of key events.
A key press
* starts with a key event with {@link #ACTION_DOWN}.
If the key is held
* sufficiently long that it repeats, then the initial down is followed
* additional key events with {@link #ACTION_DOWN} and a non-zero value for
* {@link #getRepeatCount()}.
The last key event is a {@link #ACTION_UP}
* for the key up.
If the key press is canceled, the key up event will have the
* {@link #FLAG_CANCELED} flag set.
* Key events are generally accompanied by a key code ({@link #getKeyCode()}),
* scan code ({@link #getScanCode()}) and meta state ({@link #getMetaState()}).
* Key code constants are defined in this class.
Scan code constants are raw
* device-specific codes obtained from the OS and so are not generally meaningful
* to applications unless interpreted using the {@link KeyCharacterMap}.
* Meta states describe the pressed state of key modifiers
* such as {@link #META_SHIFT_ON} or {@link #META_ALT_ON}.
* Key codes typically correspond one-to-one with individual keys on an input device.
* Many keys and key combinations serve quite different functions on different
* input devices so care must be taken when interpreting them.
Always use the
* {@link KeyCharacterMap} associated with the input device when mapping keys
* to characters.
Be aware that there may be multiple key input devices active
* at the same time and each will have its own key character map.
* As soft input methods can use multiple and inventive ways of inputting text,
* there is no guarantee that any key press on a soft keyboard will generate a key
* event: this is left to the IME's discretion, and in fact sending such events is
* discouraged.
You should never rely on receiving KeyEvents for any key on a soft
* input method.
In particular, the default software keyboard will never send any
* key event to any application targetting Jelly Bean or later, and will only send
* events for some presses of the delete and return keys to applications targetting
* Ice Cream Sandwich or earlier.
Be aware that other software input methods may
* never send key events regardless of the version.
Consider using editor actions
* like {@link android.view.inputmethod.EditorInfo#IME_ACTION_DONE} if you need
* specific interaction with the software keyboard, as it gives more visibility to
* the user as to how your application will react to key presses.
* When interacting with an IME, the framework may deliver key events
* with the special action {@link #ACTION_MULTIPLE} that either specifies
* that single repeated key code or a sequence of characters to insert.
* In general, the framework cannot guarantee that the key events it delivers
* to a view always constitute complete key sequences since some events may be dropped
* or modified by containing views before they are delivered.
The view implementation
* should be prepared to handle {@link #FLAG_CANCELED} and should tolerate anomalous
* situations such as receiving a new {@link #ACTION_DOWN} without first having
* received an {@link #ACTION_UP} for the prior key press.
* Refer to {@link InputDevice} for more information about how different kinds of
* input devices and sources represent keys and buttons.
