Inside the aforementioned onLoadMore method, load additional items into the adapter either by sending out a network request or by loading from another source.Pass in an instance of EndlessRecyclerViewScrollListener and implement the onLoadMore which fires whenever a new page needs to be loaded to fill up the list. Call addOnScrollListener(.) on a RecyclerView to enable endless pagination.In order to place multiple views in the scroll view, one needs to make a view group (like LinearLayout) as a direct child and then we can define many views inside it. A scroll view contains a single direct child only. Copy over the EndlessRecyclerViewScrollListener.java into your application. In Android, a ScrollView is a view group that is used to make vertically scrollable views.Implementing endless pagination for RecyclerView requires the following steps: For this reason, we need to pass an instance of what LayoutManager is being used to collect the necessary information to ascertain when to load more data. The LayoutManager, which is responsible in the RecyclerView for rendering where items should be positioned and manages scrolling, provides information about the current scroll position relative to the adapter. We can use a similar approach with the RecyclerView by defining an interface EndlessRecyclerViewScrollListener that requires an onLoadMore() method to be implemented. You can see this guide for more information. For more advanced cases, Google released its own Paging Library.

For Android University courses it's recommended to use this approach for simplicity.
NOTE: This page is describing a straightforward yet a bit dated solution. Adding a threshold value therefore helps anticipate the need to append more data. To provide the appearance of endless scrolling, it's important to fetch data before the user gets to the end of the list. This data can be used to decide when to load more data from an external source: In both cases, the information needed to implement the scrolling include determining the last visible item within the list and some type of threshold value to start fetching more data before the last item has been reached.

Both are similar in code except that the LayoutManager in the RecyclerView needs to be passed in to provide the necessary information to implement infinite scrolling.
The approaches for ListView, GridView and RecyclerView (the successor to ListView) are documented here. This is done by triggering a request for more data once the user crosses a threshold of remaining items before they've hit the end. A common application feature is to load automatically more items as the user scrolls through the items (aka infinite scroll).
