GridLayoutManager

Kotlin |Java

open class GridLayoutManager : LinearLayoutManager

kotlin.Any
↳	androidx.recyclerview.widget.RecyclerView.LayoutManager
	↳	androidx.recyclerview.widget.LinearLayoutManager
		↳	androidx.recyclerview.widget.GridLayoutManager

A RecyclerView.LayoutManager implementations that lays out items in a grid.

By default, each item occupies 1 span. You can change it by providing a custom SpanSizeLookup instance via setSpanSizeLookup(SpanSizeLookup).

Summary

Nested classes
	`DefaultSpanSizeLookup` Default implementation for `SpanSizeLookup`.
open	`LayoutParams` LayoutParams used by GridLayoutManager.
abstract	`SpanSizeLookup` A helper class to provide the number of spans each item occupies.

Constants
static Int	`DEFAULT_SPAN_COUNT`

Inherited constants

From class LinearLayoutManager

`Int`	`HORIZONTAL`
`Int`	`INVALID_OFFSET`
`Int`	`VERTICAL`

Public constructors
`<init>(context: Context!, attrs: AttributeSet!, defStyleAttr: Int, defStyleRes: Int)` Constructor used when layout manager is set in XML by RecyclerView attribute "layoutManager".
`<init>(context: Context!, spanCount: Int)` Creates a vertical GridLayoutManager
`<init>(context: Context!, spanCount: Int, orientation: Int, reverseLayout: Boolean)`
