[cocos2dx android]使用Bitmap中的原始数据渲染Sprite

Question

我正在尝试将URL中的图像提取到Bitmap中，然后使用Bitmap中的原始数据尝试创建CCSprite。这里的问题是Sprite显示边界宽度和高度为零。

我从网址获取图片的代码是：

String urlString ="https://graph.facebook.com/1536842063253312/picture?type=square"; //"http://www.mathewingram.com/work/wp-content/themes/thesis/rotator/335f69c5de_small.jpg";//http://graph.facebook.com/"+user.getId()+"/picture?type=large";
        Bitmap pic = null;
        try {
            pic = BitmapFactory.decodeStream((InputStream) new URL(urlString).getContent());
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            System.out.println("start fetchImageOfFacebook"+e);
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            System.out.println("start fetchImageOfFacebook"+e);  
            e.printStackTrace();
        }

        int[] pixels = new int[pic.getWidth() * pic.getHeight()];
        pic.getPixels(pixels, 0, pic.getWidth(), 0, 0, pic.getWidth(), pic.getHeight());

        int[] finalArray = new int[pic.getWidth() * pic.getHeight()];

        int len = pic.getWidth() * pic.getHeight();
        for(int i = 0; i < len; i++) {

        int red = Color.red(pixels[i]);
        int green = Color.green(pixels[i]);
        int blue = Color.blue(pixels[i]);
        finalArray[i] = Color.rgb(blue, green, red);//invert sequence here.
        }

        onFacebookImageNative(pixels,len,pic.getWidth(), pic.getHeight());


Main cpp...

JNIEXPORT void JNICALL Java_org_cocos2dx_cpp_AppActivity_onFacebookImageNative(JNIEnv* env, jobject,
    jintArray pixels, jint dataLen, jint width, jint height, jint bitsPerComponent)
{
jint *jArr = env->GetIntArrayElements(pixels, NULL);
int pixelsInt[dataLen];
for (int i=0; i<dataLen; i++){
    pixelsInt[i] = (int)jArr[i];
}

GameManager::sharedGameManager()->onFacebookImage(pixelsInt, (int) dataLen, (int) width, (int) height);
}



GameManager.cpp Class

void GameManager:: onFacebookImage(int pixelsInt[], int picLen, int picWidth, int picHeight)
{
    CCTexture2D *tex = new CCTexture2D();
    bool val = tex->initWithData(pixelsInt,picLen,(Texture2D::PixelFormat)0,picWidth,picHeight, Size(picWidth,picHeight));
    CCSprite *spriteToAdd = CCSprite::createWithTexture(tex);

    CCLog("spriteToAdd %f %f",spriteToAdd->getBoundingBox().size.width,spriteToAdd->getBoundingBox().size.height);

}
