  • surfaceCreated

    public void surfaceCreated(SurfaceHolder holder)

    Description copied from interface: SurfaceHolder.Callback
    This is called immediately after the surface is first created. Implementations of this should start up whatever rendering code they desire. Note that only one thread can ever draw into a Surface, so you should not draw into the Surface here if your normal rendering will be in another thread.

    Specified by:

    surfaceCreated in interface SurfaceHolder.Callback

    Parameters:

    holder - The SurfaceHolder whose surface is being created.

  • surfaceChanged

    public void surfaceChanged(SurfaceHolder holder,
                      int format,
                      int width,
                      int height)

    Description copied from interface: SurfaceHolder.Callback
    This is called immediately after any structural changes (format or size) have been made to the surface. You should at this point update the imagery in the surface. This method is always called at least once, after SurfaceHolder.Callback.surfaceCreated(android.view.SurfaceHolder).

    Specified by:

    surfaceChanged in interface SurfaceHolder.Callback

    Parameters:

    holder - The SurfaceHolder whose surface has changed.

    format - The new PixelFormat of the surface.

    width - The new width of the surface.

    height - The new height of the surface.

  • surfaceDestroyed

    public void surfaceDestroyed(SurfaceHolder holder)

    Description copied from interface: SurfaceHolder.Callback
    This is called immediately before a surface is being destroyed. After returning from this call, you should no longer try to access this surface. If you have a rendering thread that directly accesses the surface, you must ensure that thread is no longer touching the Surface before returning from this function.

    Specified by:

    surfaceDestroyed in interface SurfaceHolder.Callback

    Parameters:

    holder - The SurfaceHolder whose surface is being destroyed.
