How can the display of elements inside a RecyclerView be configured?

Displaying items inside a RecyclerView on Android is configured using a LayoutManager. The LayoutManager is responsible for positioning the items and their scrolling.

Main types of LayoutManager:

• LinearLayoutManager — displays items in a list (vertically or horizontally).
• GridLayoutManager — displays items in a grid with a specified number of columns or rows.
• StaggeredGridLayoutManager — displays items in a grid with varying height/width of items.

Example of setting up a RecyclerView with LinearLayoutManager:

val recyclerView: RecyclerView = findViewById(R.id.recyclerView)
recyclerView.layoutManager = LinearLayoutManager(this) // vertical list
recyclerView.adapter = myAdapter

To change the list direction, specify the parameter:

recyclerView.layoutManager = LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)

For a grid:

recyclerView.layoutManager = GridLayoutManager(this, 3) // 3 columns

Thus, to configure item display, you need to select and set the appropriate LayoutManager for RecyclerView.
