/**
|
||
|
|
* Provides a dedicated drawing surface embedded inside of a view hierarchy.
|
||
|
|
* You can control the format of this surface and, if you like, its size; the
|
||
|
|
* SurfaceView takes care of placing the surface at the correct location on the
|
||
|
|
* screen
|
||
|
|
*
|
||
|
|
* <p>The surface is Z ordered so that it is behind the window holding its
|
||
|
|
* SurfaceView; the SurfaceView punches a hole in its window to allow its
|
||
|
|
* surface to be displayed. The view hierarchy will take care of correctly
|
||
|
|
* compositing with the Surface any siblings of the SurfaceView that would
|
||
|
|
* normally appear on top of it. This can be used to place overlays such as
|
||
|
|
* buttons on top of the Surface, though note however that it can have an
|
||
|
|
* impact on performance since a full alpha-blended composite will be performed
|
||
|
|
* each time the Surface changes.
|
||
|
|
*
|
||
|
|
* <p>Access to the underlying surface is provided via the SurfaceHolder interface,
|
||
|
|
* which can be retrieved by calling {@link #getHolder}.
|
||
|
|
*
|
||
|
|
* <p>The Surface will be created for you while the SurfaceView's window is
|
||
|
|
* visible; you should implement {@link SurfaceHolder.Callback#surfaceCreated}
|
||
|
|
* and {@link SurfaceHolder.Callback#surfaceDestroyed} to discover when the
|
||
|
|
* Surface is created and destroyed as the window is shown and hidden.
|
||
|
|
*
|
||
|
|
* <p>One of the purposes of this class is to provide a surface in which a
|
||
|
|
* secondary thread can render in to the screen. If you are going to use it
|
||
|
|
* this way, you need to be aware of some threading semantics:
|
||
|
|
*
|
||
|
|
* <ul>
|
||
|
|
* <li> All SurfaceView and
|
||
|
|
* {@link SurfaceHolder.Callback SurfaceHolder.Callback} methods will be called
|
||
|
|
* from the thread running the SurfaceView's window (typically the main thread
|
||
|
|
* of the application). They thus need to correctly synchronize with any
|
||
|
|
* state that is also touched by the drawing thread.
|
||
|
|
* <li> You must ensure that the drawing thread only touches the underlying
|
||
|
|
* Surface while it is valid -- between
|
||
|
|
* {@link SurfaceHolder.Callback#surfaceCreated SurfaceHolder.Callback.surfaceCreated()}
|
||
|
|
* and
|
||
|
|
* {@link SurfaceHolder.Callback#surfaceDestroyed SurfaceHolder.Callback.surfaceDestroyed()}.
|
||
|
|
* </ul>
