Android Firebase Realtime Database - Top RecyclerView Examples.


Android Firebase Realtime Database RecyclerView Examples.

What is RecyclerView?

A RecyclerView is an adapterview that allows us display a large data set through just a limited window.

RecyclerViews were introduced in Android API 5 as an alternative to ListViews. ListView as you may already know is also an adapterview and allows us display items in a vertically scrolling list.

RecyclerView is meant to work as an adapterview, basically with an adapter that adapts data to the RecyclerView's views. AdapterViews normally display collections of data.

Even though there have been various great and popular adapterviews like ListViews, GridViews and expandablelistviews, recyclerview is the best when it comes to displaying large quantities of data.

And that's because of it's concept of recycling already used views instead of re-inflating them everytime.

Infation of views is normally expensive as it involves parsing of XML layouts into java objects. And remember this is to be done in realtime as the user scrolls through a list of data. Users can definitely notice that. And you can imagine having hundreds of rows or grids of data. Not so good isn't it?

So RecyclerView is great in this regard as instead of re-inflating the views, it holds them in a ViewHolder class and then recycles them, only binding fresh data to them. The end result is smoothness even with large datasets that we and our users can take for granted.
