Summary

Public Methods
public
void
surfaceChanged(SurfaceHolder holder, int format, int width, int height)
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
surfaceCreated(SurfaceHolder).
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.

public
void
surfaceCreated(SurfaceHolder holder)
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.
Parameters
holder
| The SurfaceHolder whose surface is being created.
|
public
void
surfaceDestroyed(SurfaceHolder holder)
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.
Parameters
holder
| The SurfaceHolder whose surface is being destroyed.
