Android在AndEngine创建第一个程序

首先要在lib文件夹中添加andengine.jar

package com.hu.anden;
 
 import org.anddev.andengine.engine.Engine;
 import org.anddev.andengine.engine.camera.Camera;
 import org.anddev.andengine.engine.options.EngineOptions;
 import org.anddev.andengine.engine.options.EngineOptions.ScreenOrientation;
 import org.anddev.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;
 import org.anddev.andengine.entity.scene.Scene;
 import org.anddev.andengine.entity.sprite.Sprite;
 import org.anddev.andengine.opengl.texture.TextureOptions;
 import org.anddev.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlas;
 import org.anddev.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlasTextureRegionFactory;
 import org.anddev.andengine.opengl.texture.region.TextureRegion;
 import org.anddev.andengine.ui.activity.BaseGameActivity;
 
 public class MainActivity extends BaseGameActivity {
 
     public static int CAMERA_WIDTH = 320;
     public static int CAMERA_HEIGHT = 480;
     
     public Camera mCamera;
     public Scene mScene;
     private BitmapTextureAtlas bgTexture;
     private TextureRegion background;
     
     public Engine onLoadEngine() {
         this.mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);//创建相机
         return new Engine(new EngineOptions(true, ScreenOrientation.PORTRAIT,
                 new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT),
                 this.mCamera));
     }
 
     public void onLoadResources() {
         bgTexture = new BitmapTextureAtlas(1024, 1024,
                 TextureOptions.BILINEAR_PREMULTIPLYALPHA);
         background = BitmapTextureAtlasTextureRegionFactory.createFromAsset(//从资产读取图片
                 bgTexture, this, "colorful.png", 0, 0);
         this.getEngine().getTextureManager().loadTextures(bgTexture);
     }
 
     public Scene onLoadScene() {
         mScene = new Scene();
         mScene.setTouchAreaBindingEnabled(true);
         return mScene;
     }
 
     public void onLoadComplete() {
         Sprite bgd = new Sprite(0, 0, background);
         mScene.attachChild(bgd);
     }
     
 }
