首先要把andengine.jar复制到libs文件夹里

01 package com.hu.anden;
02  
03 import org.anddev.andengine.engine.Engine;
04 import org.anddev.andengine.engine.camera.Camera;
05 import org.anddev.andengine.engine.options.EngineOptions;
06 import org.anddev.andengine.engine.options.EngineOptions.ScreenOrientation;
07 import org.anddev.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;
08 import org.anddev.andengine.entity.scene.Scene;
09 import org.anddev.andengine.entity.sprite.Sprite;
10 import org.anddev.andengine.opengl.texture.TextureOptions;
11 import org.anddev.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlas;
12 import org.anddev.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlasTextureRegionFactory;
13 import org.anddev.andengine.opengl.texture.region.TextureRegion;
14 import org.anddev.andengine.ui.activity.BaseGameActivity;
15  
16 public class MainActivity extends BaseGameActivity {
17  
18 public static int CAMERA_WIDTH = 320;
19 public static int CAMERA_HEIGHT = 480;
20  
21 public Camera mCamera;
22 public Scene mScene;
23 private BitmapTextureAtlas bgTexture;
24 private TextureRegion background;
25  
26 public Engine onl oadEngine() {
27 this.mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);//创建相机
28 return new Engine(new EngineOptions(true, ScreenOrientation.PORTRAIT,
29 new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT),
30 this.mCamera));
31 }
32  
33 public void onl oadResources() {
34 bgTexture = new BitmapTextureAtlas(1024, 1024,
35 TextureOptions.BILINEAR_PREMULTIPLYALPHA);
36 background = BitmapTextureAtlasTextureRegionFactory.createFromAsset(//从资产读取图片
37 bgTexture, this, "colorful.png", 0, 0);
38 this.getEngine().getTextureManager().loadTextures(bgTexture);
39 }
40  
41 public Scene onl oadScene() {
42 mScene = new Scene();
43 mScene.setTouchAreaBindingEnabled(true);
44 return mScene;
45 }
46  
47 public void onl oadComplete() {
48 Sprite bgd = new Sprite(0, 0, background);
49 mScene.attachChild(bgd);
50 }
