TextureView.SurfaceTextureListener

Kotlin |Java

public static interface TextureView.SurfaceTextureListener

android.view.TextureView.SurfaceTextureListener

This listener can be used to be notified when the surface texture associated with this texture view is available.

Summary

Public methods
`abstract void`	`onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height)` Invoked when a `TextureView`'s SurfaceTexture is ready for use.
`abstract boolean`	`onSurfaceTextureDestroyed(SurfaceTexture surface)` Invoked when the specified `SurfaceTexture` is about to be destroyed.
`abstract void`	`onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height)` Invoked when the `SurfaceTexture`'s buffers size changed.
`abstract void`	`onSurfaceTextureUpdated(SurfaceTexture surface)` Invoked when the specified `SurfaceTexture` is updated through `SurfaceTexture.updateTexImage()`.

Public methods

onSurfaceTextureAvailable

Added in API level 14

public abstract void onSurfaceTextureAvailable (SurfaceTexture surface, 
                int width, 
                int height)

Invoked when a TextureView's SurfaceTexture is ready for use.

Parameters
`surface`	`SurfaceTexture`: The surface returned by `TextureView.getSurfaceTexture()` This value cannot be `null`.
`width`	`int`: The width of the surface
`height`	`int`: The height of the surface

onSurfaceTextureDestroyed

Added in API level 14

public abstract boolean onSurfaceTextureDestroyed (SurfaceTexture surface)

Invoked when the specified SurfaceTexture is about to be destroyed. If returns true, no rendering should happen inside the surface texture after this method is invoked. If returns false, the client needs to call SurfaceTexture.release(). Most applications should return true.

Parameters
`surface`	`SurfaceTexture`: The surface about to be destroyed This value cannot be `null`.

Returns
`boolean`

onSurfaceTextureSizeChanged

Added in API level 14

public abstract void onSurfaceTextureSizeChanged (SurfaceTexture surface, 
                int width, 
                int height)

Invoked when the SurfaceTexture's buffers size changed.

Parameters
`surface`	`SurfaceTexture`: The surface returned by `TextureView.getSurfaceTexture()` This value cannot be `null`.
`width`	`int`: The new width of the surface
`height`	`int`: The new height of the surface

onSurfaceTextureUpdated

Added in API level 14

public abstract void onSurfaceTextureUpdated (SurfaceTexture surface)

Invoked when the specified SurfaceTexture is updated through SurfaceTexture.updateTexImage().

Parameters
`surface`	`SurfaceTexture`: The surface just updated This value cannot be `null`.
