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.

Public methods
describeContents
fun describeContents(): Int
Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel,int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.
| Return | |
|---|---|
Int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or
|
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
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons 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 one of the following: |

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
hashCode
fun hashCode(): Int
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.
The general contract of hashCode is:
- Whenever it is invoked on the same object more than once during an execution of a Java application, the
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equalsmethod, then calling thehashCodemethod on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal according to the
equalsmethod, then calling thehashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
| Return | |
|---|---|
Int |
a hash code value for this object. |
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 the following:
