AndEngine场景加载资源

请帮助我，我的代码有什么问题吗？在设备上显示黑色背景。

public void onLoadResources()
{

    this.mTexture = new Texture(1024, 1024);
    this.mTextureRegion = TextureRegionFactory.createFromAsset(this.mTexture, this, "gfx/bgr.png",0,0);
    this.getEngine().getTextureManager().loadTexture(this.mTexture);
}

@Override
public Scene onLoadScene()
{
    final Scene scene = new Scene(1);
    backLayer=new Sprite(0,0,this.mTextureRegion);  
    scene.getTopLayer().addEntity(backLayer);
    return scene;
}

Help me please, wat's wrong in my code? On device shown black background.

我为您提供了一些解决方案：

不要使用构造函数 Scene(int)，它已弃用。请改用Scene()。
从你的精灵名字来看，我猜这是你的场景背景？如果这是您的意图，您应该使用：scene.setBackground(new SpriteBackground(backLayer));，而不是scene.getTopLayer().addEntity(backLayer); 。

最后，我在TextureRegionFactory中没有看到createFromAsset方法。也许您应该更新您的 AndEngine 类？并尝试这个，可能会起作用：

BitmapTextureAtlastextureAtlas = new BitmapTextureAtlas(1024, 256, TextureOptions.BILINEAR_PREMULTIPLYALPHA);
BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");    
this.mTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(textureAtlas, this, "bgr.png", 0, 0);

I have a few fixes for you:

Don't use the constructor Scene(int), its deprecated. Use Scene() instead.
By your sprite's name, I guess it is your scene background? If this is your intention, you should use this: scene.setBackground(new SpriteBackground(backLayer));, instead of scene.getTopLayer().addEntity(backLayer);.

Lastly, I didn't see the method createFromAsset in TextureRegionFactory. Maybe you should update your AndEngine classes? And try this instead, might work:

BitmapTextureAtlas textureAtlas = new BitmapTextureAtlas(1024, 256, TextureOptions.BILINEAR_PREMULTIPLYALPHA);
BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");    
this.mTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(textureAtlas, this, "bgr.png", 0, 0);
