TouchImageView变焦缩放到Picasso框架

Question

我使用Universal Image Loader库加载一组图像和TouchImageView以允许缩放.我决定用毕加索取代Universal Image Loader.一切都很好,除了现在图像缩放到比图像稍大的帧.

@Override
    public Object instantiateItem(ViewGroup view, int position) {
        View imageLayout = inflater.inflate(R.layout.item_pager_image, view, false);
        assert imageLayout != null;
        TouchImageView imageView = (TouchImageView) imageLayout.findViewById(R.id.image);
        final ProgressBar spinner = (ProgressBar) imageLayout.findViewById(R.id.loading);
        spinner.setVisibility(View.INVISIBLE);
        Picasso.with(getApplicationContext()).setIndicatorsEnabled(false);
        Picasso.with(getApplicationContext()).load(images[position]).into(imageView,new Callback() {

            @Override
            public void onSuccess() {
                spinner.setVisibility(View.GONE);        
            }

            @Override
            public void onError() {

            }
        });
        view.addView(imageLayout, 0);
        return imageLayout;

为此,我几个小时就一直在挣扎.这是TouchImageView与Picasso有关的问题吗？任何帮助都会很明显.谢谢.

Mahram Foadi在这里发布了一个很适合我的解决方案:

Picasso.with(context).load (someUri).into(new Target () {
   @Override
    public void onBitmapLoaded (final Bitmap bitmap,
        final Picasso.LoadedFrom loadedFrom) {
        someTouchImageView.setImageBitmap (bitmap);
    }

   @Override
    public void onBitmapFailed (final Drawable drawable) {
       Log.d(TAG, "Failed");
    }

   @Override
   public void onPrepareLoad (final Drawable drawable) {
        someTouchImageView.setImageDrawable (drawable);
   }
});

希望这有助于像我们这样的其他人使用TouchImageView和Picasso;)
