Constants |
|
|
int |
getAction() value: the key has been pressed down. |
|
int |
getAction() value: multiple duplicate key events have occurred in a row, or a complex string is being delivered. |
|
int |
getAction() value: the key has been released. |
|
int |
When associated with up key events, this indicates that the key press has been canceled. |
|
int |
Set when a key event has FLAG_CANCELED set because a long press action was executed while it was down. |
|
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”. |
|
int |
Set when a key event has been synthesized to implement default behavior for an event that the application did not handle. |
|
int |
This mask is set if an event was known to come from a trusted part of the system. |
|
int |
This mask is set if we don’t want the key event to cause us to leave touch mode. |
|
int |
This flag is set for the first key repeat that occurs after the long press timeout. |
|
int |
This mask is set if the key event was generated by a software keyboard. |
|
int |
Set for ACTION_UP when this event’s key code is still being tracked from its initial down. |
|
int |
This key event was generated by a virtual (on-screen) hard key area. |
|
int |
This constant was deprecated in API level 20. This flag will never be set by the system since the system consumes all wake keys itself. |

Constants
added in API level 1
int ACTION_DOWN
getAction() value: the key has been pressed down.
Constant Value: 0 (0x00000000)
added in API level 1
int ACTION_MULTIPLE
getAction() value: multiple duplicate key events have occurred in a row, or a complex string is being delivered. If the key code is not {#link KEYCODE_UNKNOWN then the {#link 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().
Constant Value: 2 (0x00000002)
added in API level 1
int ACTION_UP
getAction() value: the key has been released.
Constant Value: 1 (0x00000001)
added in API level 5
int FLAG_CANCELED
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.
Constant Value: 32 (0x00000020)
added in API level 5
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.
Constant Value: 256 (0x00000100)
added in API level 3
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”. This allows TextView to dispatch these as normal enter keys for old applications, but still do the appropriate action when receiving them.
Constant Value: 16 (0x00000010)
added in API level 11
int FLAG_FALLBACK
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).
Constant Value: 1024 (0x00000400)
added in API level 3
int FLAG_FROM_SYSTEM
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.
Constant Value: 8 (0x00000008)
added in API level 3
int FLAG_KEEP_TOUCH_MODE
This mask is set if we don’t want the key event to cause us to leave touch mode.
Constant Value: 4 (0x00000004)
added in API level 5
int FLAG_LONG_PRESS
This flag is set for the first key repeat that occurs after the long press timeout.
Constant Value: 128 (0x00000080)
added in API level 3
int FLAG_SOFT_KEYBOARD
This mask is set if the key event was generated by a software keyboard.
Constant Value: 2 (0x00000002)
added in API level 5
int FLAG_TRACKING
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.
Constant Value: 512 (0x00000200)
added in API level 5
int FLAG_VIRTUAL_HARD_KEY
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.
Constant Value: 64 (0x00000040)
added in API level 1
int FLAG_WOKE_HERE
This constant was deprecated in API level 20.
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.

int getModifierMetaStateMask ()
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.
|
Returns |
|
|
int |
The modifier meta state mask which is a combination of META_SHIFT_ON, META_SHIFT_LEFT_ON, META_SHIFT_RIGHT_ON, META_ALT_ON, META_ALT_LEFT_ON, META_ALT_RIGHT_ON, META_CTRL_ON, META_CTRL_LEFT_ON, META_CTRL_RIGHT_ON, META_META_ON, META_META_LEFT_ON, META_META_RIGHT_ON, META_SYM_ON, META_FUNCTION_ON. |
added in API level 13
int getModifiers ()
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 withgetModifierMetaStateMask() so that only valid modifier bits are retained.
|
Returns |
|
|
int |
An integer in which each bit set to 1 represents a pressed modifier key. |
See also:
added in API level 1
char getNumber ()
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 KEYCODE_Q it returns ‘1’ so that the user can type numbers without pressing ALT when it makes sense.
|
Returns |
|
|
char |
The associated numeric or symbolic character, or 0 if none. |
added in API level 1
int getRepeatCount ()
Retrieve the repeat count of the event. For both key up and 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 multiple key events, this is the number of down/up pairs that have occurred.
|
Returns |
|
|
int |
The number of times the key has repeated. |
added in API level 1
int getScanCode ()
Retrieve the hardware key id of this key event. These values are not reliable and vary from device to device.

int getUnicodeChar (int metaState)
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 COMBINING_ACCENT set, the key is a “dead key” that should be combined with another to actually produce a character — see getDeadChar(int, int) — after masking with COMBINING_ACCENT_MASK.
|
Parameters |
|
|
metaState |
int: The meta key modifier state. |
|
Returns |
|
|
int |
The associated character or combining accent, or 0 if none. |
added in API level 1
int getUnicodeChar ()
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 COMBINING_ACCENT set, the key is a “dead key” that should be combined with another to actually produce a character — see getDeadChar(int, int) — after masking with COMBINING_ACCENT_MASK.
|
Returns |
|
|
int |
The associated character or combining accent, or 0 if none. |
added in API level 11
boolean hasModifiers (int modifiers)
Returns true if only the specified modifiers keys are pressed. Returns false if a different combination of modifier keys are pressed.
For the purposes of this function, KEYCODE_CAPS_LOCK, KEYCODE_SCROLL_LOCK, and KEYCODE_NUM_LOCK are not considered modifier keys. Consequently, this function ignores META_CAPS_LOCK_ON, META_SCROLL_LOCK_ON and META_NUM_LOCK_ON.
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.

boolean metaStateHasModifiers (int metaState,
int modifiers)
Returns true if only the specified modifier keys are pressed according to the specified meta state. Returns false if a different combination of modifier keys are pressed.
For the purposes of this function, KEYCODE_CAPS_LOCK, KEYCODE_SCROLL_LOCK, and KEYCODE_NUM_LOCK are not considered modifier keys. Consequently, this function ignores META_CAPS_LOCK_ON, META_SCROLL_LOCK_ON and META_NUM_LOCK_ON.
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.

int normalizeMetaState (int metaState)
Normalizes the specified meta state.
The meta state is normalized such that if either the left or right modifier meta state bits are set then the result will also include the universal bit for that modifier.
If the specified meta state contains META_ALT_LEFT_ON then the result will also contain META_ALT_ON in addition to META_ALT_LEFT_ON and the other bits that were specified in the input. The same is process is performed for shift, control and meta.
If the specified meta state contains synthetic meta states defined by MetaKeyKeyListener, then those states are translated here and the original synthetic meta states are removed from the result. META_CAP_LOCKED is translated to META_CAPS_LOCK_ON. META_ALT_LOCKED is translated to META_ALT_ON. META_SYM_LOCKED is translated to META_SYM_ON.
Undefined meta state bits are removed.
|
Parameters |
|
|
metaState |
int: The meta state. |
|
Returns |
|
|
int |
The normalized meta state. |

void startTracking ()
Call this during onKeyDown(int, KeyEvent) to have the system track the key through its final up (possibly including a long press). Note that only one key can be tracked at a time — if another key down event is received while a previous one is being tracked, tracking is stopped on the previous event.

String toString ()
Returns a string representation of the object. In general, the toString method returns a string that “textually represents” this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@‘, and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + ‘@’ + Integer.toHexString(hashCode())
|
Returns |
|
|
a string representation of the object. |

|
Parameters |
|
|
out |
Parcel: The Parcel in which the object should be written. |
|
flags |
int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE. |
