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

public interface ISurfaceHolderCallback : Android.Runtime.IJavaObject, IDisposable, Java.Interop.IJavaPeerable

type ISurfaceHolderCallback = interface

Derived: Android.App.NativeActivity

Android.Opengl.GLSurfaceView

Android.Renderscripts.RSSurfaceView

Android.Views.ISurfaceHolderCallback2

Attributes: RegisterAttribute

Implements: IJavaObject IJavaPeerable IDisposable

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)

Extension Methods

JavaCast<TResult>(IJavaObject)	Performs an Android runtime-checked type conversion.
JavaCast<TResult>(IJavaObject)
GetJniTypeName(IJavaPeerable)
