LayoutParams

Kotlin |Java

open class LayoutParams : RecyclerView.LayoutParams

kotlin.Any
↳	android.view.ViewGroup.LayoutParams
	↳	android.view.ViewGroup.MarginLayoutParams
		↳	androidx.recyclerview.widget.RecyclerView.LayoutParams
			↳	androidx.recyclerview.widget.StaggeredGridLayoutManager.LayoutParams

LayoutParams used by StaggeredGridLayoutManager.

Note that if the orientation is VERTICAL, the width parameter is ignored and if the orientation is HORIZONTAL the height parameter is ignored because child view is expected to fill all of the space given to it.

Summary

Constants
static Int	`INVALID_SPAN_ID` Span Id for Views that are not laid out yet.

Public constructors
`<init>(c: Context!, attrs: AttributeSet!)`
`<init>(width: Int, height: Int)`
`<init>(source: MarginLayoutParams!)`
`<init>(source: LayoutParams!)`
`<init>(source: RecyclerView.LayoutParams!)`

Public methods
Int	`getSpanIndex()` Returns the Span index to which this View is assigned.
open Boolean	`isFullSpan()` Returns whether this View occupies all available spans or just one.
open Unit	`setFullSpan(fullSpan: Boolean)` When set to true, the item will layout using all span area.

Inherited functions

From class LayoutParams

`Int`	`getAbsoluteAdapterPosition()` Returns the up-to-date adapter position that the view this LayoutParams is attached to corresponds to in the `RecyclerView`. If the `RecyclerView` has an `Adapter` that merges other adapters, this position will be with respect to the adapter that is assigned to the `RecyclerView`.
`Int`	`getBindingAdapterPosition()` Returns the up-to-date adapter position that the view this LayoutParams is attached to corresponds to with respect to the `Adapter` that bound this View.
`Int`	`getViewAdapterPosition()`
`Int`	`getViewLayoutPosition()` Returns the adapter position that the view this LayoutParams is attached to corresponds to as of latest layout calculation.
`Int`	`getViewPosition()`
`Boolean`	`isItemChanged()` Returns true if the adapter data item corresponding to the view this LayoutParams is attached to has been changed in the data set. A LayoutManager may choose to treat it differently in order to animate its changing state.
`Boolean`	`isItemRemoved()` Returns true if the adapter data item corresponding to the view this LayoutParams is attached to has been removed from the data set. A LayoutManager may choose to treat it differently in order to animate its outgoing or disappearing state.
`Boolean`	`isViewInvalid()` Returns true if the view this LayoutParams is attached to is now representing potentially invalid data. A LayoutManager should scrap/recycle it.
`Boolean`	`viewNeedsUpdate()` Returns true if the view this LayoutParams is attached to needs to have its content updated from the corresponding adapter.
