Android Picasso get remote pictures and show

Picasso is an open source Android graphics cache Library at square, address http://square.github.io/picasso/, which allows for image download and caching capabilities.

It is simple to use and simply requires a single line of code to fully implement the asynchronous loading of the image:

        Picasso.with (View.getcontext ()). Load (newsitems.get (position). Getthumb ()). into (Holder.ivheader); // Picasso loading a preview image asynchronously

Images can be loaded without any other action at all, with the ability to cache, optimize the reuse of images in Recyclerview, and use sophisticated image compression algorithms to reduce memory consumption and bring your own level two cache
