KeyEvent

Kotlin |Java

open class KeyEvent : InputEvent, Parcelable

kotlin.Any
↳	android.view.InputEvent
	↳	android.view.KeyEvent

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 ACTION_DOWN. If the key is held sufficiently long that it repeats, then the initial down is followed additional key events with ACTION_DOWN and a non-zero value for getRepeatCount(). The last key event is a ACTION_UP for the key up. If the key press is canceled, the key up event will have the FLAG_CANCELED flag set.

Key events are generally accompanied by a key code (getKeyCode()), scan code (getScanCode()) and meta state (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 KeyCharacterMap. Meta states describe the pressed state of key modifiers such as META_SHIFT_ON or 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 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 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.

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 FLAG_CANCELED and should tolerate anomalous situations such as receiving a new ACTION_DOWN without first having received an ACTION_UP for the prior key press.

Refer to InputDevice for more information about how different kinds of input devices and sources represent keys and buttons.

Constants
static Int	`ACTION_DOWN` `getAction` value: the key has been pressed down.
static Int	`ACTION_MULTIPLE`
static Int	`ACTION_UP` `getAction` value: the key has been released.
static Int	`FLAG_CANCELED` When associated with up key events, this indicates that the key press has been canceled.
static Int	`FLAG_CANCELED_LONG_PRESS` Set when a key event has `FLAG_CANCELED` set because a long press action was executed while it was down.
static Int	`FLAG_EDITOR_ACTION` This mask is used for compatibility, to identify enter keys that are coming from an IME whose enter key has been auto-labelled "next" or "done".
static Int	`FLAG_FALLBACK` Set when a key event has been synthesized to implement default behavior for an event that the application did not handle.

Constants

ACTION_DOWN

Added in API level 1

static val ACTION_DOWN: Int

getAction value: the key has been pressed down.

Value: 0

ACTION_MULTIPLE

Added in API level 1
Deprecated in API level 29

static val ACTION_MULTIPLE: Int

Deprecated: No longer used by the input system. getAction value: multiple duplicate key events have occurred in a row, or a complex string is being delivered. If the key code is not KEYCODE_UNKNOWN then the getRepeatCount() method returns the number of times the given key code should be executed. Otherwise, if the key code is KEYCODE_UNKNOWN, then this is a sequence of characters as returned by getCharacters.

Value: 2

ACTION_UP

Added in API level 1

static val ACTION_UP: Int

getAction value: the key has been released.

Value: 1

FLAG_CANCELED

Added in API level 5

static val FLAG_CANCELED: Int

When associated with up key events, this indicates that the key press has been canceled. Typically this is used with virtual touch screen keys, where the user can slide from the virtual key area on to the display: in that case, the application will receive a canceled up event and should not perform the action normally associated with the key. Note that for this to work, the application can not perform an action for a key until it receives an up or the long press timeout has expired.

Value: 32

FLAG_CANCELED_LONG_PRESS

Added in API level 5

static val FLAG_CANCELED_LONG_PRESS: Int

Set when a key event has FLAG_CANCELED set because a long press action was executed while it was down.

Value: 256

FLAG_EDITOR_ACTION

Added in API level 3

static val FLAG_EDITOR_ACTION: Int

This mask is used for compatibility, to identify enter keys that are coming from an IME whose enter key has been auto-labelled "next" or "done". This allows TextView to dispatch these as normal enter keys for old applications, but still do the appropriate action when receiving them.

Value: 16

FLAG_FALLBACK

Added in API level 11

static val FLAG_FALLBACK: Int

Set when a key event has been synthesized to implement default behavior for an event that the application did not handle. Fallback key events are generated by unhandled trackball motions (to emulate a directional keypad) and by certain unhandled key presses that are declared in the key map (such as special function numeric keypad keys when numlock is off).

Value: 1024

FLAG_FROM_SYSTEM

Added in API level 3

static val FLAG_FROM_SYSTEM: Int

This mask is set if an event was known to come from a trusted part of the system. That is, the event is known to come from the user, and could not have been spoofed by a third party component.

Value: 8

FLAG_KEEP_TOUCH_MODE

Added in API level 3

static val FLAG_KEEP_TOUCH_MODE: Int

This mask is set if we don't want the key event to cause us to leave touch mode.

Value: 4

FLAG_LONG_PRESS

Added in API level 5

static val FLAG_LONG_PRESS: Int

This flag is set for the first key repeat that occurs after the long press timeout.

Value: 128

FLAG_SOFT_KEYBOARD

Added in API level 3

static val FLAG_SOFT_KEYBOARD: Int

This mask is set if the key event was generated by a software keyboard.

Value: 2

FLAG_TRACKING

Added in API level 5

static val FLAG_TRACKING: Int

Set for ACTION_UP when this event's key code is still being tracked from its initial down. That is, somebody requested that tracking started on the key down and a long press has not caused the tracking to be canceled.

Value: 512

FLAG_VIRTUAL_HARD_KEY

Added in API level 5

static val FLAG_VIRTUAL_HARD_KEY: Int

This key event was generated by a virtual (on-screen) hard key area. Typically this is an area of the touchscreen, outside of the regular display, dedicated to "hardware" buttons.

Value: 64

FLAG_WOKE_HERE

Added in API level 1
Deprecated in API level 20

static val FLAG_WOKE_HERE: Int

Deprecated: This flag will never be set by the system since the system consumes all wake keys itself.

This mask is set if the device woke because of this key event.

Value: 1
