picasso

问题 From the UX point of view, it will be great to show the user a thumbnail first until the real image completes loading, then showing it to him, but Picasso uses only a resource file as the place holder like: Picasso.with(context) .load(url) .placeholder(R.drawable.user_placeholder) .into(imageView); So, how can I use a thumbnail URL as the placeholder? , and if I should use Picasso twice, then how?
