onLoadMoreListener won't stop loading - RecyclerView - Android -

i have user feed user's posts displayed if current user following them, @ moment have loadmorelistener working fine in regards loading next batch of images when bottom of recyclerview. but, when reach last item (the feeds shows 50 posts) in list it'll attempt load more , cause outofmemoryexception. i've restricted size of list in adapter, @ minute can't seem work out when user has hit bottom stop progress displaying , stop onloadmorelistener triggering. have tried far:

adapter constructor:

 public recyclerviewadapterallfeeds(context context,                                        final arraylist<allfeedsdatamodel> previouspostslist, final boolean profile, recyclerview recyclerview, final progressbar progressbar) {         this.context = context;         this.previouspostslist = previouspostslist;         this.profile = profile;         if(recyclerview.getlayoutmanager() instanceof linearlayoutmanager){             final linearlayoutmanager linearlayoutmanager = (linearlayoutmanager)recyclerview.getlayoutmanager();             recyclerview.addonscrolllistener(new recyclerview.onscrolllistener() {                 @override                 public void onscrolled(recyclerview recyclerview, int dx, int dy) {                     super.onscrolled(recyclerview, dx, dy);                     progressbar.setvisibility(view.visible);                         if (getitemcount() > loaded_posts - 2) {                             totalitemcount = getitemcount(); //                            total_posts = getitemcount();                             lastvisibleitem = linearlayoutmanager.findlastvisibleitemposition();                             if (lastvisibleitem <= total_posts) {                                 if (!loading && totalitemcount <= (lastvisibleitem)) {                                     if (onloadmorelistener != null) {                                         onloadmorelistener.onloadmore();                                     }                                     loading = true;                                 }                             }                         }                 }             });         }     } 

onloadmorelistener

 adapter = new recyclerviewadapterallfeeds(getactivity(), latestupdateslist, false, recyclerview, progressbar);                             recyclerview.setadapter(adapter);// set adapter on recyclerview                             adapter.setonloadmorelistener(new recyclerviewadapterallfeeds.onloadmorelistener() {                                 @override                                 public void onloadmore() {                                     refreshcount++;                                     populaterecyclerview(true, refreshcount);                                     adapter.update(updateslist);                                     adapter.setloaded();                                     system.out.println("load");                                 }                             });                             adapter.notifydatasetchanged();// notify adapter                             progressbar.setindeterminate(false);                             progressbar.setvisibility(view.invisible); 

my question how can stop loading if total posts less of restrictions or know when final item visible?

first create endlessrecyclerviewscrolllistener.java:

import android.support.v7.widget.gridlayoutmanager; import android.support.v7.widget.linearlayoutmanager; import android.support.v7.widget.recyclerview; import android.support.v7.widget.staggeredgridlayoutmanager;  public abstract class endlessrecyclerviewscrolllistener extends recyclerview.onscrolllistener {     // minimum amount of items have below current scroll position     // before loading more.     private int visiblethreshold = 5;     // current offset index of data have loaded     private int currentpage = 0;     // total number of items in dataset after last load     private int previoustotalitemcount = 0;     // true if still waiting last set of data load.     private boolean loading = true;     // sets starting page index     private int startingpageindex = 0;      recyclerview.layoutmanager mlayoutmanager;      public endlessrecyclerviewscrolllistener(linearlayoutmanager layoutmanager) {         this.mlayoutmanager = layoutmanager;     }      public endlessrecyclerviewscrolllistener(gridlayoutmanager layoutmanager) {         this.mlayoutmanager = layoutmanager;         visiblethreshold = visiblethreshold * layoutmanager.getspancount();     }      public endlessrecyclerviewscrolllistener(staggeredgridlayoutmanager layoutmanager) {         this.mlayoutmanager = layoutmanager;         visiblethreshold = visiblethreshold * layoutmanager.getspancount();     }      public int getlastvisibleitem(int[] lastvisibleitempositions) {         int maxsize = 0;         (int = 0; < lastvisibleitempositions.length; i++) {             if (i == 0) {                 maxsize = lastvisibleitempositions[i];             } else if (lastvisibleitempositions[i] > maxsize) {                 maxsize = lastvisibleitempositions[i];             }         }         return maxsize;     }      // happens many times second during scroll, wary of code place here.     // given few useful parameters work out if need load more data,     // first check if waiting previous load finish.     @override     public void onscrolled(recyclerview view, int dx, int dy) {         int lastvisibleitemposition = 0;         int totalitemcount = mlayoutmanager.getitemcount();          if (mlayoutmanager instanceof staggeredgridlayoutmanager) {             int[] lastvisibleitempositions = ((staggeredgridlayoutmanager) mlayoutmanager).findlastvisibleitempositions(null);             // maximum element within list             lastvisibleitemposition = getlastvisibleitem(lastvisibleitempositions);         } else if (mlayoutmanager instanceof linearlayoutmanager) {             lastvisibleitemposition = ((linearlayoutmanager) mlayoutmanager).findlastvisibleitemposition();         } else if (mlayoutmanager instanceof gridlayoutmanager) {             lastvisibleitemposition = ((gridlayoutmanager) mlayoutmanager).findlastvisibleitemposition();         }          // if total item count 0 , previous isn't, assume         // list invalidated , should reset initial state         if (totalitemcount < previoustotalitemcount) {             this.currentpage = this.startingpageindex;             this.previoustotalitemcount = totalitemcount;             if (totalitemcount == 0) {                 this.loading = true;             }         }         // if it’s still loading, check see if dataset count has         // changed, if conclude has finished loading , update current page         // number , total item count.         if (loading && (totalitemcount > previoustotalitemcount)) {             loading = false;             previoustotalitemcount = totalitemcount;         }          // if isn’t loading, check see if have breached         // visiblethreshold , need reload more data.         // if need reload more data, execute onloadmore fetch data.         // threshold should reflect how many total columns there         if (!loading && (lastvisibleitemposition + visiblethreshold) > totalitemcount) {             currentpage++;             onloadmore(currentpage, totalitemcount);             loading = true;         }     }      // defines process loading more data based on page     public abstract void onloadmore(int page, int totalitemscount);  } 

and implement in way:

recyclerview.addonscrolllistener(new endlessrecyclerviewscrolllistener(recyclerview.getlayoutmanager()) {             @override             public void onloadmore(int page, int totalitemscount) {                  //todo add logic load more posts or show message if posts ended.              }         });
