Question

我正在尝试在壁纸活动中将图像添加到背景中。但我无法这样做，有人可以提出一些方法来做，这是我的代码：

menuBackgroundTexture = new BitmapTextureAtlas（getTextureManager（），   2 * CAMERA_WIDTH，2 * CAMERA_HEIGHT，TextureOptions.DEFAULT）;

menuBgTexture = BitmapTextureAtlasTextureRegionFactory.createFromAsset（this.menuBackgroundTexture，   这个，＆＃34; land.png＆＃34;，0,0）;

我尝试使用

之后

this.menuBackgroundTexture.load（）;   但它不起作用，我也试过以下代码   SpriteBackground bg = new SpriteBackground（new Sprite（0,0，   menuBgTexture，this.getVertexBufferObjectManager（）））;

mScene.setBackground（BG）;

这也行不通，请帮帮我。

我终于找到了办法。以下是相同的代码：

final BitmapTexture backgroundTexture = new BitmapTexture（this.getTextureManager（），new IInputStreamOpener（）{ @覆盖 public InputStream open（）抛出IOException {
            return getAssets().open("gfx/background1.jpg");
        }
    });
    backgroundTexture.load();
    backgroundTextureRegion = TextureRegionFactory.extractFromTexture(backgroundTexture); final
Sprite background = new Sprite（CAMERA_WIDTH / 2f - backgroundTextureRegion.getWidth（）/ 2f，CAMERA_HEIGHT / 2f - backgroundTextureRegion.getHeight（）/ 2f，backgroundTextureRegion， this.getVertexBufferObjectManager（））; mScene.attachChild（背景）;

我希望它可以帮助其他人。

@Rahul，也在我的壁纸服务中的wallaper活动代码下面工作

public class MagicWallpaper extends BaseLiveWallpaperService {

private TextureRegion region;

@Override
public EngineOptions onCreateEngineOptions() {
    calculateWidthAndHeight();
    Camera mCamera = new Camera(0, 0, Helper.GAME_WIDTH, Helper.GAME_HEIGHT);
    EngineOptions engOptions = new EngineOptions(true,
            ScreenOrientation.PORTRAIT_FIXED, new FillResolutionPolicy(),
            mCamera);
    return engOptions;
}

@SuppressWarnings("deprecation")
private void calculateWidthAndHeight() {
    Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE))
            .getDefaultDisplay();
    Helper.GAME_WIDTH = display.getWidth();
    Helper.GAME_HEIGHT = display.getHeight();
}

@Override
public void onCreateResources(
        OnCreateResourcesCallback pOnCreateResourcesCallback)
        throws Exception {

    BitmapTextureAtlas atlas = new BitmapTextureAtlas(getTextureManager(),
            600, 1024);
    region = BitmapTextureAtlasTextureRegionFactory.createFromAsset(atlas,
            this, "wall.png", 0, 0);
    atlas.load();
    pOnCreateResourcesCallback.onCreateResourcesFinished();
}

@Override
public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback)
        throws Exception {
    mEngine.registerUpdateHandler(new FPSLogger());
    Scene dScene = new Scene();
    dScene.setBackground(new SpriteBackground(new Sprite(0, 0, region,
            getVertexBufferObjectManager())));
    pOnCreateSceneCallback.onCreateSceneFinished(dScene);
}

@Override
public void onPopulateScene(Scene pScene,
        OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception {
    pOnPopulateSceneCallback.onPopulateSceneFinished();
}

}

无法在AndEngine中设置场景的背景图像？
