Types

ViewportFiller

open class ViewportFiller : LayoutInfo.ViewportFiller

Simple implementation of LayoutInfo.ViewportFiller which fills the viewport by laying out items sequentially.

Functions

approximateRangeSize

open fun approximateRangeSize(firstMeasuredItemWidth: Int, firstMeasuredItemHeight: Int, recyclerMeasuredWidth: Int, recyclerMeasuredHeight: Int): Int

This is called when the RecyclerBinder needs to calculate a range size.

computeWrappedHeight

open fun computeWrappedHeight(maxHeight: Int, componentTreeHolders: List<ComponentTreeHolder>): Int

createViewportFiller

open fun createViewportFiller(measuredWidth: Int, measuredHeight: Int): LinearLayoutInfo.ViewportFiller

findFirstFullyVisibleItemPosition

open fun findFirstFullyVisibleItemPosition(): Int

findFirstVisibleItemPosition

open fun findFirstVisibleItemPosition(): Int

findLastFullyVisibleItemPosition

open fun findLastFullyVisibleItemPosition(): Int

findLastVisibleItemPosition

open fun findLastVisibleItemPosition(): Int

getChildHeightSpec

open fun getChildHeightSpec(heightSpec: Int, renderInfo: RenderInfo): Int

getChildWidthSpec

open fun getChildWidthSpec(widthSpec: Int, renderInfo: RenderInfo): Int

getItemCount

open fun getItemCount(): Int

getLayoutManager

open fun getLayoutManager(): RecyclerView.LayoutManager

getScrollDirection

open fun getScrollDirection(): Int

This is the main scrolling direction that the LayoutManager passed to this binder will use.

scrollToPositionWithOffset

open fun scrollToPositionWithOffset(position: Int, offset: Int)

RecyclerBinder delegates scrolling responsibilities to the LayoutInfo, as the varied LayoutManagers wrapped by a LayoutInfo lack a common scrolling interface.

setRenderInfoCollection

open fun setRenderInfoCollection(@Nullable renderInfoCollection: LayoutInfo.RenderInfoCollection)
