Lazy layouts in Compose

Lazy layouts

Jetpack Compose is a modern toolkit for creating native Android user interfaces, if you've ever used RecyclerView before, you'll be very familiar with the main concept behind Lazy layouts.

Lazy layouts are used for rendering a scrollable list of items as they become visible on the screen rather than all at once.

In cases where you have a significant number of items or large data sets to load, using Lazy layouts would allow you to add content on-demand, increasing your app's performance and responsiveness.

Currently, in compose, 1.2 Lazy layouts consist of:

• lazy column, a vertically scrolling list.

• lazy row, a horizontal one.

• lazy grids, which offers both.

  

There is, however, a big difference between the RecyclerView used in the view system and the lazy list used in the Compose.

• The amount of code you need is a lot to write

  RecyclerView adapter and view holder, RecyclerView XML layouts and then the layout for the RecyclerView item, and finally, binding the adapter to your RecyclerView.

• With Lazy lists, they achieve the same result with fewer lines of code, which make them notably easier and simpler to read and write.
