Question

我正在尝试了解andEngine中的精灵。我写了下面的代码来加载一个简单的图像“img”

package com.example.pxc;

import org.andengine.engine.camera.Camera;
import org.andengine.engine.options.EngineOptions;
import org.andengine.engine.options.ScreenOrientation;
import org.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;
import org.andengine.entity.scene.Scene;
import org.andengine.entity.sprite.Sprite;
import org.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlas;
import org.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlasTextureRegionFactory;
import org.andengine.opengl.texture.atlas.bitmap.BuildableBitmapTextureAtlas;
import org.andengine.opengl.texture.atlas.bitmap.source.IBitmapTextureAtlasSource;
import org.andengine.opengl.texture.atlas.buildable.builder.BlackPawnTextureAtlasBuilder;
import org.andengine.opengl.texture.atlas.buildable.builder.ITextureAtlasBuilder.TextureAtlasBuilderException;
import org.andengine.opengl.texture.region.ITextureRegion;
import org.andengine.ui.activity.SimpleBaseGameActivity;

public class TestActivity extends SimpleBaseGameActivity {

    static final int CAMERA_WIDTH = 800;
    static final int CAMERA_HEIGHT = 480;
    BuildableBitmapTextureAtlas bbta;
    ITextureRegion msr;
    @Override
    public EngineOptions onCreateEngineOptions() {
        Camera mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);
        return new EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED,
            new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), mCamera);
    }

    @Override
    protected void onCreateResources() {
        // TODO Auto-generated method stub
        BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");
         bbta = new BuildableBitmapTextureAtlas(mEngine.getTextureManager(), 256, 256);  
        msr=BitmapTextureAtlasTextureRegionFactory.createFromAsset(bbta, this, "img.png");
        try{
        bbta.build(new BlackPawnTextureAtlasBuilder<IBitmapTextureAtlasSource, BitmapTextureAtlas>(0, 1, 1));
        bbta.load();

                } catch (TextureAtlasBuilderException e) {
                e.printStackTrace();
                }       
    }

    @Override
    protected Scene onCreateScene() {
        Scene scene = new Scene();
        Sprite mSprite = new Sprite(0, 0,
                msr, mEngine.getVertexBufferObjectManager());
        scene.attachChild(mSprite);
        return scene;
    }
}

上面的代码编译没有任何错误。当我运行代码时，我会看到模拟器上的黑屏而不是图像。为什么会这样？我该如何解决这个问题？

如果您想首先在模拟器上运行，则必须提供this link中所示的设置如果你想要有效的fps获得好的fps，那么关注link可以帮助你

运行代码的黑屏
