android - Scroll effect for RecyclerView -


i using horisontal recyclerview in android app.
showing 2 items (imageviews) on screen @ time.

to setting width of each imageview half of screen in viewholder class of adapter:

  public static class viewholder extends recyclerview.viewholder {     private linearlayout ll_img;         private imageview iv_ad;           private viewholder(view v) {             super(v);              ll_img = (linearlayout) itemview.findviewbyid(r.id.ll_img);             ll_img.getlayoutparams().width = (utils.getscreenwidth(itemview.getcontext()) / 2);              iv_ad = (imageview) v.findviewbyid(r.id.iv_main_ad);         }     }

and getting scrren width: 

public static int getscreenwidth(context context) {      windowmanager wm = (windowmanager) context.getsystemservice(context.window_service);     display display = wm.getdefaultdisplay();     point size = new point();     display.getsize(size);     int screenwidth = size.x;      return screenwidth; }

it works fine want implement scroll effect on ios,
scroll 1 item per swipe,
after each swipe 2 items must fit screen width.

by way, 2 videos worth 1000 words
here having now: https://drive.google.com/file/d/0b7j1rf_oueblowk1outpwxfpcee/view?usp=sharing

and want achieve (as colleague implemented on ios): https://drive.google.com/file/d/0b6b-4-itg1eqtelntwsxmwg4aws/view?usp=sharing

each piece of advice appreciated

this viewpager, not recyclerview. link might https://commonsware.com/blog/2012/08/20/multiple-view-viewpager-options.html

just else's benefit:

getpagewidth() returns floating-point number, between 0 , 1, representing portion of width of viewpager given page should take up. default, page width 1, overriding this, can have multiple pages on screen simultaneously.
