Implement Endless scrolling using StaggeredLayoutManager – Android

You can use one of two methods in the StaggeredGridLayoutManager:

1. mLayoutManager.findFirstVisibleItemPositions 
2. mLayoutManager.findFirstCompletelyVisibleItemPositions

Pass an empty int array that will get initialized with the positions and use the one that makes sense for you.

private boolean loading = true;  
 private int pastVisibleItems, visibleItemCount, totalItemCount;  
 mRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener({  
     @Override  
     public void onScrolled(RecyclerView recyclerView, int dx, int dy) {  
     visibleItemCount = mLayoutManager.getChildCount();  
     totalItemCount = mLayoutManager.getItemCount();  
     int[] firstVisibleItems = null;  
     firstVisibleItems = mLayoutManager.findFirstVisibleItemPositions(firstVisibleItems);  
     if(firstVisibleItems != null && firstVisibleItems.length > 0) {  
       pastVisibleItems = firstVisibleItems[0];  
     }  
     if (loading) {  
       if ((visibleItemCount + pastVisibleItems) >= totalItemCount) {  
         loading = false;  
         Log.d("tag", "LOAD NEXT ITEM");  
       }  
     }  
   }  
 });
