andengine入门教程之学习笔记
例子中主程序.launcher.ExampleLauncher主要继承自ExpandableListActivity的列表,
这里主要定义了另个枚举public enum ExampleGroup和enum Example ，平时因为像他们这样使用比较少，值得学习。
| 代码如下 | 复制代码 |

上面的public final Class<? extends BaseGameActivity> CLASS;表示任何继承自BaseGameActivity的类型，属于泛型，
因为andengine的例子程序都是继承自BaseGameActivity。
| 代码如下 | 复制代码 |
|
public enum ExampleGroup { // =========================================================== // Elements // ===========================================================
SIMPLE(R.string.examplegroup_simple, Example.LINE, Example.RECTANGLE, Example.SPRITE, Example.SPRITEREMOVE), MODIFIER_AND_ANIMATION(R.string.examplegroup_modifier_and_animation, Example.MOVINGBALL, Example.SHAPEMODIFIER, Example.SHAPEMODIFIERIRREGULAR, Example.PATHMODIFIER, Example.ANIMATEDSPRITES, Example.EASEFUNCTION, Example.ROTATION3D ), TOUCH(R.string.examplegroup_touch, Example.TOUCHDRAG, Example.MULTITOUCH, Example.ANALOGONSCREENCONTROL, Example.DIGITALONSCREENCONTROL, Example.ANALOGONSCREENCONTROLS, Example.COORDINATECONVERSION, Example.PINCHZOOM), PARTICLESYSTEM(R.string.examplegroup_particlesystems, Example.PARTICLESYSTEMSIMPLE, Example.PARTICLESYSTEMCOOL, Example.PARTICLESYSTEMNEXUS), MULTIPLAYER(R.string.examplegroup_multiplayer, Example.MULTIPLAYER), PHYSICS(R.string.examplegroup_physics, Example.COLLISIONDETECTION, Example.PHYSICS, Example.PHYSICSFIXEDSTEP, Example.PHYSICSCONLLISIONFILTERING, Example.PHYSICSJUMP, Example.PHYSICSREVOLUTEJOINT, Example.PHYSICSREMOVE ), TEXT(R.string.examplegroup_text, Example.TEXT, Example.TICKERTEXT, Example.CHANGEABLETEXT, Example.CUSTOMFONT, Example.STROKEFONT), AUDIO(R.string.examplegroup_audio, Example.SOUND, Example.MUSIC, Example.MODPLAYER), ADVANCED(R.string.examplegroup_advanced, Example.SPLITSCREEN, Example.BOUNDCAMERA ), // Example.AUGMENTEDREALITY, Example.AUGMENTEDREALITYHORIZON), BACKGROUND(R.string.examplegroup_background, Example.REPEATINGSPRITEBACKGROUND, Example.AUTOPARALLAXBACKGROUND, Example.TMXTILEDMAP), OTHER(R.string.examplegroup_other, Example.PAUSE, Example.MENU, Example.SUBMENU, Example.TEXTMENU, Example.ZOOM , Example.IMAGEFORMATS, Example.TEXTUREOPTIONS, Example.COLORKEYTEXTURESOURCEDECORATOR, Example.LOADTEXTURE, Example.UPDATETEXTURE, Example.XMLLAYOUT, Example.LEVELLOADER), APP(R.string.examplegroup_app, Example.APP_CITYRADAR), GAME(R.string.examplegroup_game, Example.GAME_SNAKE, Example.GAME_RACER), BENCHMARK(R.string.examplegroup_benchmark, Example.BENCHMARK_SPRITE, Example.BENCHMARK_SHAPEMODIFIER, Example.BENCHMARK_ANIMATION, Example.BENCHMARK_TICKERTEXT, Example.BENCHMARK_PARTICLESYSTEM, Example.BENCHMARK_PHYSICS);

主程序就比较简单，不再介绍了。
