Android PagerAdapter::获取当前项目到位图中

Question

我正在为我的应用程序使用 UniversalImageLoader。我的 ImageAdapter 扩展了 PagerAdapter。我需要 currentImage 作为位图。通过回调方法 public void onLoadingComplete(Bitmap loadedImage) 我得到了位图。但这不是当前显示的位图图像。它是下一张图像或上一张图像(取决于交换)。这是完整的代码:

    private class ImagePagerAdapter extends PagerAdapter {
    private String[] images;
    private LayoutInflater inflater;

    ImagePagerAdapter(String[] images) {
        this.images = images;
        inflater = getLayoutInflater();
    }

    @Override
    public void destroyItem(View container, int position, Object object) {
        ((ViewPager) container).removeView((View) object);
    }

    @Override
    public void finishUpdate(View container) {
    }

    @Override
    public int getCount() {
        return images.length;
    }

    @Override
    public Object instantiateItem(View view, int position) {
        if (view != null) {
            final View imageLayout = inflater.inflate(
                    R.layout.item_pager_image, null);
            final ImageView imageView = (ImageView) imageLayout
                    .findViewById(R.id.image_item_pager);

            imageLoader.displayImage(images[position], imageView, options,
                    new ImageLoadingListener() {

                        @Override
                        public void onLoadingStarted() {
                        }

                        @Override
                        public void onLoadingFailed(FailReason failReason) {
                            //On Loading Failed Logic                               
                        }

                        @Override
                        public void onLoadingComplete(Bitmap loadedImage) {
                                                        bitmap = loadedImage;  
                            imgViewSetAsWp.setImageBitmap(bitmap);
                        }

                        @Override
                        public void onLoadingCancelled() {
                            // Do nothing
                        }
                    });


            ((ViewPager) view).addView(imageLayout, 0);

            return imageLayout;
        } else
            return view;
    }

    @Override
    //Other override methood of ImagePager

}

有什么方法可以得到正确的位图。

如何获取当前 View - https://stackoverflow.com/a/8638772/913762

然后:

View currentView = ...
ImageView currentImageView = (ImageView) currentView.findViewById(...);
BitmapDrawable bd = (BitmapDrawable) currentImageView.getDrawable();
Bitmap bmp = bd.getBitmap();
