Constructors

Name Description
KeyCharacterMap(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Fields

Name Description
CombiningAccent

Identifies a combining accent in a key character value.

CombiningAccentMask

Mask the return value from #get(int, int) with this value to get a printable representation of the accent character of a "dead key.

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

Name Description
Class

Returns the runtime class of this Object.

(Inherited from Object)
Creator

Gets the parcelable creator for KeyCharacterMap instances.

Handle

The handle to the underlying Android instance.

(Inherited from Object)
JniIdentityHashCode

Gets the identity hash code assigned to this Java peer by the interop runtime.

(Inherited from Object)
JniManagedPeerState (Inherited from JavaObject)
JniPeerMembers

Gets the JNI peer metadata used by the .NET for Android binding runtime.

KeyboardType

Gets the keyboard type. Returns NUMERIC , PREDICTIVE , ALPHA , FULL or SPECIAL_FUNCTION . Different keyboard types have different semantics. Refer to the documentation associated with the keyboard type constants for details.

ModifierBehavior

Gets a constant that describes the behavior of this keyboard's modifier keys such as KeyEvent#KEYCODE_SHIFT_LEFT.

PeerReference

Gets the JNI object reference for this Java peer.

(Inherited from Object)
ThresholdClass

Gets the JNI class handle used by the .NET for Android binding runtime.

ThresholdType

Gets the managed type used by the .NET for Android binding runtime.

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.

JavaFinalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

(Inherited from Object)
Load(Int32)

(Inherited from Object)
NotifyAll()

Wakes up all threads that are waiting on this object's monitor.

(Inherited from Object)
SetHandle(IntPtr, JniHandleOwnership)

Sets the Handle property.

(Inherited from Object)
SetPeerReference(JniObjectReference, JniObjectReferenceOptions) (Inherited from JavaObject)
ToArray<T>()

Creates a managed array from this Java array wrapper.

(Inherited from Object)
ToString()

Returns a string representation of the object.

(Inherited from Object)
UnregisterFromRuntime()

Unregisters this Java peer from the interop runtime.

(Inherited from Object)
Wait()

Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>.

(Inherited from Object)
Wait(Int64, Int32)

Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed.

(Inherited from Object)
Wait(Int64)

Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed.

(Inherited from Object)
WriteToParcel(Parcel, ParcelableWriteFlags)

Flatten this object in to a Parcel.
