| CombiningAccentMask |
Mask the return value from |
| HexInput |
This private-use character is used to trigger Unicode character input by hex digits. |
| PickerDialogInput |
This private-use character is used to bring up a character picker for miscellaneous symbols. |
Properties

Methods
| Name | Description |
|---|---|
| Clone() |
Creates and returns a copy of this object. (Inherited from Object) |
| Construct(JniObjectReference, JniObjectReferenceOptions) | (Inherited from JavaObject) |
| DescribeContents() |
Describe the kinds of special objects contained in this Parcelable's marshalled representation. |
| DeviceHasKey(Keycode) |
Queries the framework about whether any physical keys exist on any currently attached input devices that are capable of producing the given key code. |
| DeviceHasKeys(Keycode[]) |
Queries the framework about whether any physical keys exist on any currently attached input devices that are capable of producing the given array of key codes. |
| Dispose() |
Releases the resources held by this Java peer. (Inherited from Object) |
| Dispose(Boolean) |
Releases the resources held by this Java peer. (Inherited from Object) |
| DisposeUnlessReferenced() | (Inherited from JavaObject) |
| Equals(Object) | (Inherited from JavaObject) |
| Equals(Object) |
Indicates whether some other object is "equal to" this one. (Inherited from Object) |
| Get(Keycode, Int32) |
Gets the character or code point produced by the specified key code and meta state. |
| Get(Keycode, MetaKeyStates) |
Gets the Unicode character generated by the specified key and meta key state combination. |
| GetDeadChar(Int32, Int32) |
Get the character that is produced by combining the dead key producing accent with the key producing character c. |
| GetDisplayLabel(Keycode) |
Gets the primary character for this key. In other words, the label that is physically printed on it. |
| GetEvents(Char[]) |
Get an array of KeyEvent objects that if put into the input stream could plausibly generate the provided sequence of characters. |
| GetHashCode() |
Returns a hash code value for the object. (Inherited from Object) |
| GetKeyData(Keycode, KeyCharacterMap+KeyData) |
Obsolete.
Get the character conversion data for a given key code. |
| GetMatch(Keycode, Char[], Int32) |
Gets the first candidate character that the specified key can produce with the given meta state. |
| GetMatch(Keycode, Char[], MetaKeyStates) |
Gets the first character in the character array that can be generated by the specified key code. |
| GetMatch(Keycode, Char[]) |
Gets the first character in the character array that can be generated by the specified key code. |
| GetNumber(Keycode) |
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. |
| IsPrintingKey(Keycode) |
Returns true if the specified key produces a glyph. |
