public class StaggeredGridLayoutManager.LayoutParams extends RecyclerView.LayoutParams

java.lang.Object
↳	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.
