Android 和引擎背景图像

最近我开始从事安德林的工作

我正在尝试设置场景的背景图像

但由于某些原因，背景图像没有完全填满屏幕

有什么建议和帮助吗

以下是我的源代码：

public class MainActivity extends BaseGameActivity {

Scene sc;

protected final static int cam_wid = 320;

protected final static int cam_heigh = 456;

BitmapTextureAtlas texAtlas;

    ITextureRegion texRegion;

    @Override
    public EngineOptions onCreateEngineOptions() {
        // TODO Auto-generated method stub
        Camera ca = new Camera(0, 0, cam_wid, cam_heigh);
        EngineOptions en = new EngineOptions(true,
                ScreenOrientation.LANDSCAPE_FIXED, new RatioResolutionPolicy(
                        cam_wid, cam_heigh), ca);
        return en;
    }

    @Override
    public void onCreateResources(
            OnCreateResourcesCallback pOnCreateResourcesCallback)
            throws Exception {
        // TODO Auto-generated method stub
        load();
        pOnCreateResourcesCallback.onCreateResourcesFinished();
    }

    private void load() {
        // TODO Auto-generated method stub
        BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");
        texAtlas = new BitmapTextureAtlas(getTextureManager(), 256, 512);
        texRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(
                texAtlas, this, "imagery.png", 0, 0);
        texAtlas.load();
    }

    @Override
    public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback)
            throws Exception {
        // TODO Auto-generated method stub
        this.sc = new Scene();
        Sprite s = new Sprite(0, 0, cam_wid, cam_heigh, texRegion,
                this.mEngine.getVertexBufferObjectManager());
        SpriteBackground sb = new SpriteBackground(s);
        sc.setBackground(sb);
        pOnCreateSceneCallback.onCreateSceneFinished(sc);
    }

    @Override
    public void onPopulateScene(Scene pScene,
            OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception {
        // TODO Auto-generated method stub
        pOnPopulateSceneCallback.onPopulateSceneFinished();
    }

}

如下图所示获取设备的宽度和高度并使用它

DisplayMetrics dm = new DisplayMetrics();
this.getWindowManager().getDefaultDisplay().getMetrics(dm);
cam_wid =dm.widthPixels;
cam_heigh =dm.heightPixels;

另一方面，你的背景图片可能比你的屏幕小（低）。

所以，要么缩放图片，要么重复。在最后一种情况下，您可以将纹理图集设置为

纹理选项。重复双线性

，然后使您的精灵变大。

我仍然无法解决问题。我尝试根据手机的宽度和高度调整图像的宽度和高度值。@user3624963请使用我的代码调整相机宽度和高度height@user3624963和你们的影像尺寸是多少？宽度是256，高度是512
