ISurfaceHolderCallback Interface

Definition

A client may implement this interface to receive information about changes to the surface.

[Android.Runtime.Register("android/view/SurfaceHolder$Callback", "", "Android.Views.ISurfaceHolderCallbackInvoker")]
public interface ISurfaceHolderCallback : Android.Runtime.IJavaObject, IDisposable, Java.Interop.IJavaPeerable
[<Android.Runtime.Register("android/view/SurfaceHolder$Callback", "", "Android.Views.ISurfaceHolderCallbackInvoker")>]
type ISurfaceHolderCallback = interface
    interface IJavaObject
    interface IDisposable
    interface IJavaPeerable

Remarks

A client may implement this interface to receive information about changes to the surface. When used with a SurfaceView, the Surface being held is only available between calls to #surfaceCreated(SurfaceHolder) and #surfaceDestroyed(SurfaceHolder). The Callback is set with SurfaceHolder#addCallback SurfaceHolder.addCallback method.

Properties

Handle

Gets the JNI value of the underlying Android object.

(Inherited from IJavaObject)
JniIdentityHashCode

Returns the value of java.lang.System.identityHashCode() for the wrapped instance.

(Inherited from IJavaPeerable)
JniManagedPeerState

State of the managed peer.

(Inherited from IJavaPeerable)
JniPeerMembers

Member access and invocation support.

(Inherited from IJavaPeerable)
PeerReference

Returns a JniObjectReference of the wrapped Java object instance.

(Inherited from IJavaPeerable)

Methods

Disposed()

Called when the instance has been disposed.

(Inherited from IJavaPeerable)
DisposeUnlessReferenced()

If there are no outstanding references to this instance, then calls Dispose(); otherwise, does nothing.

(Inherited from IJavaPeerable)
Finalized()

Called when the instance has been finalized.

(Inherited from IJavaPeerable)
SetJniIdentityHashCode(Int32)

Set the value returned by JniIdentityHashCode.

(Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates) (Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)

Set the value returned by PeerReference.

(Inherited from IJavaPeerable)
SurfaceChanged(ISurfaceHolder, Format, Int32, Int32)

This is called immediately after any structural changes (format or size) have been made to the surface.

SurfaceCreated(ISurfaceHolder)

This is called immediately after the surface is first created.

SurfaceDestroyed(ISurfaceHolder)

This is called immediately before a surface is being destroyed.

UnregisterFromRuntime()

Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations.

(Inherited from IJavaPeerable)
