How To Create Pagination In Chat App Using Firebase Real Time Database?

from documentation that says the paging adapter is not appropriate for a chat application so i tried to make pagination in swipeTorefreshLayout swipeRefreshLayout.setOnRefreshList

Solution 1:

I personally dont use the adapters when utilising Pagination, I simply send the current List size to my service layer, when the user reaches the bottom of a ListView. Seems like a less intensive and more efficient process, then you just need to implement SKIP and TAKE to the db

privatebooleanreachedEndOfList(int position)
    {
        returnposition== this.getCount() - 1;
    }

Solution 2:

u can try this method

privatevoidmyRecyclerUpdater() {
    mRecycleView.addOnScrollListener(newRecyclerView.OnScrollListener() {
        publicvoidonScrolled(RecyclerView recyclerView, int dx, int dy) {       //not importantsuper.onScrolled(recyclerView, dx, dy);
        }

        publicvoidonScrollStateChanged(RecyclerView recyclerView, int newState) {
            super.onScrollStateChanged(recyclerView, newState);
     
   //try (2) instead of ACTION_DOWN if it didnt work   //and we check for scroll state here 0 means IDLE if (!recyclerView.canScrollVertically(MotionEvent.ACTION_DOWN) && newState == 0) {
          //make your data request//update your recycler list and notify changes
            }
        }
    });

}
