Is it okay to initialize endlessly scrolling adapter with null?

[shymmq]

I was wondering if I always have to add some starting elements in order to endless scroll to work?
Let's say I initialize my adapter with FlexibleAdapter<IFlexible> adapter = new FlexibleAdapter<>(null);
Then i set EndlessScrollListener on it, for example adapter.setEndlessScrollListener(this, progressItem);.
In this case, will onLoadMore fire on startup? In all examples i have seen there are some starting items.
Is this considered a good practice?

@shymmq, indeed, at the moment you need to bind something to trigger it (not the progressItem!), one item is necessary.
If I added if (getItemCount() == 0) onLoadMore(0); when setting the first time the progress, it will start automatically. But you can tell me better, since you are using it more than me: when adapter is empty at startup, better an implicit automatic start or a boolean settings?

However, this also works: your remote method at startup and also show the progressItem with mAdapter.addScrollableFooter(mProgressItem);

Thank you, that makes sense. I think that something like adapter.loadMoreOnStartup(boolean b) would be perfect. It should be set to false by default, though, so it doesn't break any old code.
