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. * </p><p> * 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}. * </p><p> * 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. * </p><p> * 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. * </p><p> * 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. * </p><p> * 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. * </p><p> * Refer to {@link InputDevice} for more information about how different kinds of * input devices and sources represent keys and buttons. * </p> */ public class KeyEvent extends InputEvent implements Parcelable { /** Key code constant: Unknown key code. */ public static final int KEYCODE_UNKNOWN = 0;
