Creator CREATOR ```

## Public methods ### describeContents Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int describeContents () ``` 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)](https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)), the return value of this method must include the [CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR) bit.
| Returns || |-------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or [CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR)
| ### equals Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean equals (Object o) ``` 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 return `true`. - It is *symmetric* : for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`. - It is *transitive* : for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`. - It is *consistent* : for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified. - For any non-null reference value `x`, `x.equals(null)` should return `false`. 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 || |-----|--------------------------------------------| | `o` | `Object`: This value may be `null`.
| | Returns || |-----------|----------------------------------------------------------------------------------| | `boolean` | `true` if this object is the same as the obj argument; `false` otherwise.
| ### getAction Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int getAction () ``` The action of this key event. May be either [KeyEvent.ACTION_DOWN](https://developer.android.com/reference/android/view/KeyEvent#ACTION_DOWN) or [KeyEvent.ACTION_UP](https://developer.android.com/reference/android/view/KeyEvent#ACTION_UP).
| Returns || |-------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `int` | Value is [KeyEvent.ACTION_DOWN](https://developer.android.com/reference/android/view/KeyEvent#ACTION_DOWN), or [KeyEvent.ACTION_UP](https://developer.android.com/reference/android/view/KeyEvent#ACTION_UP)
| **See also:** - [KeyEvent.getAction()](https://developer.android.com/reference/android/view/KeyEvent#getAction()) ### getDownTimeNanos Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public long getDownTimeNanos () ``` Retrieve the time of the most recent key down event, in the [SystemClock.uptimeMillis()](https://developer.android.com/reference/android/os/SystemClock#uptimeMillis()) time base, but in nanoseconds. If this is a down event, this will be the same as [VerifiedInputEvent.getEventTimeNanos()](https://developer.android.com/reference/android/view/VerifiedInputEvent#getEventTimeNanos()).
| Returns || |--------|--------| | `long` |
| **See also:** - [KeyEvent.getDownTime()](https://developer.android.com/reference/android/view/KeyEvent#getDownTime()) ### getFlag Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Boolean getFlag (int flag) ``` 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
| | Returns || |----------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [Boolean](https://developer.android.com/reference/java/lang/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
| **See also:** - [KeyEvent.getFlags()](https://developer.android.com/reference/android/view/KeyEvent#getFlags()) - [KeyEvent.FLAG_CANCELED](https://developer.android.com/reference/android/view/KeyEvent#FLAG_CANCELED) ### getKeyCode Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int getKeyCode () ``` Retrieve the key code of the key event.
| Returns || |-------|--------| | `int` |
| **See also:** - [KeyEvent.getKeyCode()](https://developer.android.com/reference/android/view/KeyEvent#getKeyCode()) ### getMetaState Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int getMetaState () ```
Returns the state of the meta keys.

| Returns || |-------|----------------------------------------------------------------------------| | `int` | an integer in which each bit set to 1 represents a pressed meta key
| **See also:** - [KeyEvent.getMetaState()](https://developer.android.com/reference/android/view/KeyEvent#getMetaState()) ### getRepeatCount Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int getRepeatCount () ``` 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.
| Returns || |-------|--------| | `int` |
| ### getScanCode Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int getScanCode () ``` Retrieve the hardware key id of this key event. These values are not reliable and vary from device to device.
| Returns || |-------|--------| | `int` |
| **See also:** - [KeyEvent.getScanCode()](https://developer.android.com/reference/android/view/KeyEvent#getScanCode()) ### hashCode Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int hashCode () ``` Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by [HashMap](https://developer.android.com/reference/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 `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons 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 [equals](https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)) method, then calling the `hashCode` method 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 [equals](https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)) method, then calling the `hashCode` method 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.

| Returns || |-------|-------------------------------------------| | `int` | a hash code value for this object.
| ### writeToParcel Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void writeToParcel (Parcel dest, int flags) ``` 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.PARCELABLE_WRITE_RETURN_VALUE](https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE). Value is either `0` or a combination of [Parcelable.PARCELABLE_WRITE_RETURN_VALUE](https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE), and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
