image.setVisibility(View.GONE);

view.findViewById(R.id.imageLoading).setVisibility(View.VISIBLE);

"http://example.com/images/"

+ p.image).openStream());

image.compress(Bitmap.CompressFormat.JPEG, 85,

new FileOutputStream(imageFile));

image.recycle();

}

image = BitmapFactory.decodeFile(imageFile.getPath(),

bitmapOptions);

return image;

}

@Override

return;

view.findViewById(R.id.imageLoading).setVisibility(

View.GONE);

view.findViewById(R.id.image)
