Imageview在小imageview上设置大图像

Question

默认情况下，我设置了一个66 x 66的小图片。当我想借助上面提到的URL更改它时，我无法设置大小为200 X 200的图像。它设置为仅66 X 66。

class DownloadImage extends AsyncTask<Void, Integer, Bitmap>{

    ImageView imageView;
    LinearLayout.LayoutParams lp;
    public DownloadImage(ImageView iv){
        imageView = iv;
    }

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();
        Animation anim = AnimationUtils.loadAnimation(cxt, R.anim.progress_anim);
        anim.setFillAfter(true);
        anim.setDuration(300);
        imageView.startAnimation(anim);
    }

    @Override
    protected void onProgressUpdate(Integer... values) {
        // TODO Auto-generated method stub
        imageView.clearAnimation();
        imageView.requestLayout();
        imageView.postInvalidate();
        imageView.setImageBitmap(null);
        imageView.setImageResource(0);
        super.onProgressUpdate(values);
    }

    @Override
    protected Bitmap doInBackground(Void... params) {
        // TODO Auto-generated method stub
        String url = (String) imageView.getTag();           
        try {
            //              Bitmap unscaledBitmap = ScalingUtilities.decodeResource(cxt.getResources(),R.drawable.photo,200, 200, ScalingUtilities.ScalingLogic.FIT);
            Bitmap unscaledBitmap = ScalingUtilities.decodeStream(new URL(url),200, 200, ScalingUtilities.ScalingLogic.FIT);
            Bitmap scaledBitmap = ScalingUtilities.createScaledBitmap(unscaledBitmap, 200, 200,  ScalingUtilities.ScalingLogic.FIT);
            unscaledBitmap.recycle();
            if(scaledBitmap!=null)
                publishProgress(1);
            return scaledBitmap;
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            return null;
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            return null;
        }
    }

    @Override
    protected void onPostExecute(final Bitmap result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);
        if(result!=null){
            imageView.setImageBitmap(result);
        }
        imageView.postInvalidate();
    }

}

}
