VerifiedKeyEvent
class VerifiedKeyEvent : VerifiedInputEvent, Parcelable
kotlin.Any | ||
↳ | android.view.VerifiedInputEvent | |
↳ | android.view.VerifiedKeyEvent |
KeyEvent that has been verified by the system. The data contained in this class is always a subset of a KeyEvent
. Use this class to check which data has been confirmed by the system to be authentic. Most applications do not need to use this class. {@see android.hardware.input.InputManager#verifyInputEvent}

Public methods
describeContents
fun describeContents(): Int
Return | |
---|---|
Int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR |
equals
fun equals(other: Any?): Boolean
Indicates whether some other object is "equal to" this one.
The equals
method implements an equivalence relation on non-null object references:
- It is reflexive: for any non-null reference value
x
,x.equals(x)
should returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
Parameters | |
---|---|
obj |
the reference object with which to compare. |
o |
This value may be null . |
Return | |
---|---|
Boolean |
true if this object is the same as the obj argument; false otherwise. |
getAction
fun getAction(): Int
The action of this key event. May be either KeyEvent#ACTION_DOWN
or KeyEvent#ACTION_UP
.
Return | |
---|---|
Int |
Value is android.view.KeyEvent#ACTION_DOWN , or android.view.KeyEvent#ACTION_UP |
See Also
getDownTimeNanos
fun getDownTimeNanos(): Long
Retrieve the time of the most recent key down event, in the android.os.SystemClock#uptimeMillis
time base, but in nanoseconds. If this is a down event, this will be the same as VerifiedInputEvent#getEventTimeNanos()
.
See Also
getFlag
fun getFlag(flag: Int): Boolean?
Get a specific flag of this key event, if possible. Return null if the flag value could not be checked.
Parameters | |
---|---|
flag |
Int: the flag of interest |
Return | |
---|---|
Boolean? |
Boolean(true) if the key event has the requested flag Boolean(false) if the key event does not have the requested flag null if the flag value could not be checked |
getKeyCode
fun getKeyCode(): Int
Retrieve the key code of the key event.
See Also
getMetaState
fun getMetaState(): Int
Returns the state of the meta keys.
Return | |
---|---|
Int |
an integer in which each bit set to 1 represents a pressed meta key |
See Also
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.
getScanCode
fun getScanCode(): Int
Retrieve the hardware key id of this key event. These values are not reliable and vary from device to device.
See Also
writeToParcel
fun writeToParcel(
dest: Parcel,
flags: Int
): Unit
Flatten this object in to a Parcel.
Parameters | |
---|---|
dest |
Parcel: This value cannot be null . |
flags |
Int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE . Value is either 0 or a combination of android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
