KeyEvent
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.
When interacting with an IME, the framework may deliver key events with the special action 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 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
ACTION_DOWN
static val ACTION_DOWN: Int
getAction value: the key has been pressed down.
Value: 0
ACTION_MULTIPLE
static valACTION_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
static val ACTION_UP: Int
getAction value: the key has been released.
Value: 1
FLAG_CANCELED
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
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
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
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

This flag is set for the first key repeat that occurs after the long press timeout.
Value: 128
FLAG_SOFT_KEYBOARD
static val FLAG_SOFT_KEYBOARD: Int
This mask is set if the key event was generated by a software keyboard.
Value: 2
FLAG_TRACKING
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
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

getModifierMetaStateMask
open static fun getModifierMetaStateMask(): Int
Gets a mask that includes all valid modifier key meta state bits.
For the purposes of this function, KEYCODE_CAPS_LOCK, KEYCODE_SCROLL_LOCK, and KEYCODE_NUM_LOCK are not considered modifier keys. Consequently, the mask specifically excludes META_CAPS_LOCK_ON, META_SCROLL_LOCK_ON and META_NUM_LOCK_ON.
| Return | |
|---|---|

getModifiers
fun getModifiers(): Int
Returns the state of the modifier keys.
For the purposes of this function, KEYCODE_CAPS_LOCK, KEYCODE_SCROLL_LOCK, and KEYCODE_NUM_LOCK are not considered modifier keys. Consequently, this function specifically masks out META_CAPS_LOCK_ON, META_SCROLL_LOCK_ON and META_NUM_LOCK_ON.
The value returned consists of the meta state (from getMetaState) normalized using normalizeMetaState(int) and then masked with getModifierMetaStateMask so that only valid modifier bits are retained.
| Return | |
|---|---|
Int |
An integer in which each bit set to 1 represents a pressed modifier key. |
See Also
getNumber
open fun getNumber(): Char
Gets the number or symbol associated with the key.
The character value is returned, not the numeric value. If the key is not a number, but is a symbol, the symbol is retuned.
This method is intended to to support dial pads and other numeric or symbolic entry on keyboards where certain keys serve dual function as alphabetic and symbolic keys. This method returns the number or symbol associated with the key independent of whether the user has pressed the required modifier.
For example, on one particular keyboard the keys on the top QWERTY row generate numbers when ALT is pressed such that ALT-Q maps to '1'. So for that keyboard when getNumber is called with KeyEvent#KEYCODE_Q it returns '1' so that the user can type numbers without pressing ALT when it makes sense.
| Return | |
|---|---|
Char |
The associated numeric or symbolic character, or 0 if none. |
getRepeatCount
fun getRepeatCount(): Int
Retrieve the repeat count of the event. For key down events, this is the number of times the key has repeated with the first down starting at 0 and counting up from there. For key up events, this is always equal to zero. For multiple key events, this is the number of down/up pairs that have occurred.
| Return | |
|---|---|
Int |
The number of times the key has repeated. |
getScanCode
fun getScanCode(): Int
Retrieve the hardware key id of this key event. These values are not reliable and vary from device to device. {@more} Mostly this is here for debugging purposes.
getSource
fun getSource(): Int
Gets the source of the event.
| Return | |
|---|---|
Int |
The event source or InputDevice#SOURCE_UNKNOWN if unknown. |
getUnicodeChar
open fun getUnicodeChar(): Int
Gets the Unicode character generated by the specified key and meta key state combination.
Returns the Unicode character that the specified key would produce when the specified meta bits (see MetaKeyKeyListener) were active.
Returns 0 if the key is not one that is used to type Unicode characters.
If the return value has bit KeyCharacterMap#COMBINING_ACCENT set, the key is a "dead key" that should be combined with another to actually produce a character -- see KeyCharacterMap#getDeadChar -- after masking with KeyCharacterMap#COMBINING_ACCENT_MASK.
| Return | |
|---|---|
Int |
The associated character or combining accent, or 0 if none. |
getUnicodeChar
open fun getUnicodeChar(metaState: Int): Int
Gets the Unicode character generated by the specified key and meta key state combination.
Returns the Unicode character that the specified key would produce when the specified meta bits (see MetaKeyKeyListener) were active.
Returns 0 if the key is not one that is used to type Unicode characters.

If the specified modifier mask includes directional modifiers, such as META_SHIFT_LEFT_ON, then this method ensures that the modifier is pressed on that side. If the specified modifier mask includes non-directional modifiers, such as META_SHIFT_ON, then this method ensures that the modifier is pressed on either side. If the specified modifier mask includes both directional and non-directional modifiers for the same type of key, such as META_SHIFT_ON and META_SHIFT_LEFT_ON, then this method throws an illegal argument exception.
| Parameters | |
|---|---|
