Initializer used internally by JCOBridge. Do not use directly.
[Obsolete("This public initializer is needed for JCOBridge internal use, other uses can produce unidentifiable behaviors.")]

initializerIJVMBridgeBaseInitializer
BaseKeyListener(params object[])
Generic constructor used by JCOBridge when a derived class needs to forward arguments to the base JVMBridgeBase class.

Properties
BridgeClassName
Java class name to be instantiated
public override string BridgeClassName { get; }Property Value
OnBackspace
public Func<View, Editable, int, KeyEvent, bool> OnBackspace { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnBackspaceDispose
Optional handler invoked after the event handler returns, to dispose the JVM object returned by this event.
public Action<bool> OnBackspaceDispose { get; set; }Property Value
Remarks
Set OnBackspaceDispose when the event handler returns a JVM-backed object that is no longer needed after the call. The handler receives the return value and is responsible for calling Dispose() on it, releasing the underlying JVM global reference immediately instead of waiting for the .NET garbage collector to finalize it. If not set, the return value is not disposed automatically.
OnClearMetaKeyState
public Func<long, int, long> OnClearMetaKeyState { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnClearMetaKeyState3
public Action<View, Editable, int> OnClearMetaKeyState3 { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnClearMetaKeyStateDispose
Optional handler invoked after the event handler returns, to dispose the JVM object returned by this event.
public Action<long> OnClearMetaKeyStateDispose { get; set; }Property Value
Remarks
Set OnClearMetaKeyStateDispose when the event handler returns a JVM-backed object that is no longer needed after the call. The handler receives the return value and is responsible for calling Dispose() on it, releasing the underlying JVM global reference immediately instead of waiting for the .NET garbage collector to finalize it. If not set, the return value is not disposed automatically.
OnForwardDelete
public Func<View, Editable, int, KeyEvent, bool> OnForwardDelete { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnForwardDeleteDispose
Optional handler invoked after the event handler returns, to dispose the JVM object returned by this event.
public Action<bool> OnForwardDeleteDispose { get; set; }Property Value
Remarks
Set OnForwardDeleteDispose when the event handler returns a JVM-backed object that is no longer needed after the call. The handler receives the return value and is responsible for calling Dispose() on it, releasing the underlying JVM global reference immediately instead of waiting for the .NET garbage collector to finalize it. If not set, the return value is not disposed automatically.
OnGetInputType
Handler for https://developer.android.com/reference/android/text/method/KeyListener.html#getInputType()
public Func<int> OnGetInputType { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnGetInputTypeDispose
Optional handler invoked after the event handler returns, to dispose the JVM object returned by this event.
public Action<int> OnGetInputTypeDispose { get; set; }Property Value
Remarks
Set OnGetInputTypeDispose when the event handler returns a JVM-backed object that is no longer needed after the call. The handler receives the return value and is responsible for calling Dispose() on it, releasing the underlying JVM global reference immediately instead of waiting for the .NET garbage collector to finalize it. If not set, the return value is not disposed automatically.
OnOnKeyOther
public Func<View, Editable, KeyEvent, bool> OnOnKeyOther { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnOnKeyOtherDispose
Optional handler invoked after the event handler returns, to dispose the JVM object returned by this event.
public Action<bool> OnOnKeyOtherDispose { get; set; }Property Value
Remarks
Set OnOnKeyOtherDispose when the event handler returns a JVM-backed object that is no longer needed after the call. The handler receives the return value and is responsible for calling Dispose() on it, releasing the underlying JVM global reference immediately instead of waiting for the .NET garbage collector to finalize it. If not set, the return value is not disposed automatically.
OnOnKeyUp
public Func<View, Editable, int, KeyEvent, bool> OnOnKeyUp { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnOnKeyUpDispose
Optional handler invoked after the event handler returns, to dispose the JVM object returned by this event.
public Action<bool> OnOnKeyUpDispose { get; set; }Property Value
Remarks
Set OnOnKeyUpDispose when the event handler returns a JVM-backed object that is no longer needed after the call. The handler receives the return value and is responsible for calling Dispose() on it, releasing the underlying JVM global reference immediately instead of waiting for the .NET garbage collector to finalize it. If not set, the return value is not disposed automatically.

ListenerShallManageEvent(int)
Invoked from the JVMBridgeListener on each received event to notify the user which can decide to abort the execution for the specific event returning false
protected override bool ListenerShallManageEvent(int eventIndex)Parameters
eventIndexintThe index of the event triggered as returned from AddEventHandler(string, EventHandler) or AddEventHandler<TDataClass>(string, EventHandler<CLRListenerEventArgs<TDataClass>>)
Returns
Remarks
By default every event continues the execution and reads the data from JVM; this implies an extra cost which can be limited using ListenerShallManageEvent(int) or the ListenerShallManageEventIndex/ListenerShallManageEventName handlers. Returning false the control is immediately returned to the JVM, anyway the user has received the notification. It can be useful in scenarios where the user is interested in few events and the other are simply discarded to optimize the execution speed. By default, this function invokes ListenerShallManageEventIndex, then try ListenerShallManageEventName if they are set or return true
