/** | |
* Object used to report key and button events. | |
* <p> | |
* 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. | |
* </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> | |
