//adapter    public class recycleimageadapter extends recyclerview.adapter<recycleimageadapter.viewholder> {        private list<string> itemlist;      private context mcontext;        public recycleimageadapter(context context, list<string> itemlist) {          this.itemlist = itemlist;          this.mcontext = context;      }        @override      public viewholder oncreateviewholder(viewgroup parent, int viewtype) {          view view = layoutinflater.from(parent.getcontext()).inflate(r.layout.imagelayout, parent, false);          return new viewholder(view);      }        @override      public void onbindviewholder(final viewholder holder, int position) {                uri uri = uri.parse(itemlist.get(position));              holder.setimageview(uri);        }        @override      public int getitemcount() {          return this.itemlist.size();      }        class viewholder extends recyclerview.viewholder implements view.onclicklistener{            imageview image, delbtn;            viewholder(view itemview) {              super(itemview);              image = (imageview) itemview.findviewbyid(r.id.img_thumbnail);              delbtn = (imageview)itemview.findviewbyid(r.id.del);              delbtn.setonclicklistener(this);          }            public void setimageview(uri uri){              picasso.with(mcontext).load(uri).into(new target() {                  @override                  public void onbitmaploaded(bitmap bitmap, picasso.loadedfrom from) {                      image.setimagebitmap(bitmap);                  }                    @override                  public void onbitmapfailed(drawable errordrawable) {                      log.e("sammy_error"," "+errordrawable);                  }                    @override                  public void onprepareload(drawable placeholderdrawable) {                    }              });          }            @override          public void onclick(view view) {  //here i'm deleting image              int position = getadapterposition();              toast.maketext(mcontext, itemlist.get(position), toast.length_short).show();                  file file = new file(itemlist.get(position));              file.delete();                itemlist.remove(position);              notifyitemremoved(position);              notifyitemrangechanged(position, itemlist.size());          }      }  }
