Android Firebase Realtime Database - Top GridView Examples.


Android Firebase Realtime Database GridView Examples.

What is GridView?

A gridview is an adapterview that shows items in a two-dimensional grid.

Android GridView

These grids are scrollable. GridView is an adapterview because it works with adapters. Adapters can then bind data to the gridview.

This is important because then it means that the gridview is decoupled from it's data source. So you can customize the gridview as you like without interfering with the data source. You can also work on the data source without affecting the visual appearance of the gridview.

GridView derives from AbsListview.

public class GridView extends android.widget.AbsListView{}

Both reside in the android.widget packages.

AbsListview is an abstract class and you won't use in directly. You'll use it in case you want to implement your own custom view with unique properties.

Even the sister of GridView which is ListView also directly derives from AbsListview. So AbsListview is a base class. It's used to implement virtualized list of items. Given it's virtualized you can implement it to show lists in various forms:

  • Lists -vertical and horizontal
  • Grids
  • Carousel
  • Stack

And so on.
