| 48 | * Provides a dedicated drawing surface embedded inside of a view hierarchy. |
| 49 | * You can control the format of this surface and, if you like, its size; the |
| 50 | * SurfaceView takes care of placing the surface at the correct location on the |
| 51 | * screen |
Igor Murashkin | a86ab640 | 2013-08-30 12:58:36 -0700 | [diff] [blame] | 52 | * |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 53 | * <p>The surface is Z ordered so that it is behind the window holding its |
| 54 | * SurfaceView; the SurfaceView punches a hole in its window to allow its |
Jesse Hall | c9f345f | 2012-09-26 11:55:16 -0700 | [diff] [blame] | 55 | * surface to be displayed. The view hierarchy will take care of correctly |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 56 | * compositing with the Surface any siblings of the SurfaceView that would |
Jesse Hall | c9f345f | 2012-09-26 11:55:16 -0700 | [diff] [blame] | 57 | * normally appear on top of it. This can be used to place overlays such as |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 58 | * buttons on top of the Surface, though note however that it can have an |
| 59 | * impact on performance since a full alpha-blended composite will be performed |
| 60 | * each time the Surface changes. |
Igor Murashkin | a86ab640 | 2013-08-30 12:58:36 -0700 | [diff] [blame] | 61 | * |
Jesse Hall | c9f345f | 2012-09-26 11:55:16 -0700 | [diff] [blame] | 62 | * <p> The transparent region that makes the surface visible is based on the |
| 63 | * layout positions in the view hierarchy. If the post-layout transform |
| 64 | * properties are used to draw a sibling view on top of the SurfaceView, the |
| 65 | * view may not be properly composited with the surface. |
| 66 | * |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 67 | * <p>Access to the underlying surface is provided via the SurfaceHolder interface, |
| 68 | * which can be retrieved by calling {@link #getHolder}. |
Igor Murashkin | a86ab640 | 2013-08-30 12:58:36 -0700 | [diff] [blame] | 69 | * |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 70 | * <p>The Surface will be created for you while the SurfaceView's window is |
| 71 | * visible; you should implement {@link SurfaceHolder.Callback#surfaceCreated} |
| 72 | * and {@link SurfaceHolder.Callback#surfaceDestroyed} to discover when the |
| 73 | * Surface is created and destroyed as the window is shown and hidden. |

The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 75 | * <p>One of the purposes of this class is to provide a surface in which a |
Jesse Hall | c9f345f | 2012-09-26 11:55:16 -0700 | [diff] [blame] | 76 | * secondary thread can render into the screen. If you are going to use it |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 77 | * this way, you need to be aware of some threading semantics: |
Igor Murashkin | a86ab640 | 2013-08-30 12:58:36 -0700 | [diff] [blame] | 78 | * |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 79 | * <ul> |
| 80 | * <li> All SurfaceView and |
| 81 | * {@link SurfaceHolder.Callback SurfaceHolder.Callback} methods will be called |
| 82 | * from the thread running the SurfaceView's window (typically the main thread |
Jesse Hall | c9f345f | 2012-09-26 11:55:16 -0700 | [diff] [blame] | 83 | * of the application). They thus need to correctly synchronize with any |
The Android Open Source Project | 54b6cfa | 2008-10-21 07:00:00 -0700 | [diff] [blame] | 84 | * state that is also touched by the drawing thread. |
| 85 | * <li> You must ensure that the drawing thread only touches the underlying |
| 86 | * Surface while it is valid -- between |
| 87 | * {@link SurfaceHolder.Callback#surfaceCreated SurfaceHolder.Callback.surfaceCreated()} |
| 88 | * and |
| 89 | * {@link SurfaceHolder.Callback#surfaceDestroyed SurfaceHolder.Callback.surfaceDestroyed()}. |
| 90 | * </ul> |
Chris Craik | 6ee192f | 2016-05-17 14:29:10 -0700 | [diff] [blame] | 91 | * |
| 92 | * <p class="note"><strong>Note:</strong> Starting in platform version |
| 93 | * {@link android.os.Build.VERSION_CODES#N}, SurfaceView's window position is |
| 94 | * updated synchronously with other View rendering. This means that translating |
| 95 | * and scaling a SurfaceView on screen will not cause rendering artifacts. Such |
| 96 | * artifacts may occur on previous versions of the platform when its window is |
| 97 | * positioned asynchronously.</p> |
