It\'s all working properly. Now

Answer 1

This solution is inspired by Akshar Patels solution on this page. I modified it a bit.

1. When loading the first items it looks nice to have the ProgressBar centered.

2. I didn't like the remaining empty padding at the bottom when there existed no more items to load. That has been removed with this solution.

First the XML:

Then I added the following programmatically.

When first results been loaded, add this to your onScrollListener. It moves the ProgressBar from center to the bottom:

ConstraintLayout.LayoutParams layoutParams = (ConstraintLayout.LayoutParams) loadingVideos.getLayoutParams();
layoutParams.topToTop = ConstraintLayout.LayoutParams.UNSET;
loadingVideos.setLayoutParams(layoutParams);

When no more items exist, remove the padding at the bottom like this:

recyclerView.setPadding(0,0,0,0);

Hide and show your ProgressBar as usual.
