Functions

approximateRangeSize

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

This is called when the RecyclerBinder needs to calculate a range size. The returned value should be an approximate range size based on the size of the first measured item.

computeWrappedHeight

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

createViewportFiller

open override fun createViewportFiller(measuredWidth: Int, measuredHeight: Int): LayoutInfo.ViewportFiller?

findFirstFullyVisibleItemPosition

open override fun findFirstFullyVisibleItemPosition(): Int

findFirstVisibleItemPosition

open override fun findFirstVisibleItemPosition(): Int

findLastFullyVisibleItemPosition

open override fun findLastFullyVisibleItemPosition(): Int

findLastVisibleItemPosition

open override fun findLastVisibleItemPosition(): Int

getChildHeightSpec

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

getChildWidthSpec

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

getItemCount

open override fun getItemCount(): Int

getLayoutManager

open override fun getLayoutManager(): RecyclerView.LayoutManager

getScrollDirection

open override fun getScrollDirection(): Int

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

scrollToPositionWithOffset

open override 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. Typical implementations should forward the call to the underlying LayoutManager's scrollToPositionWithOffset() or an equivalent.

setRenderInfoCollection

open override fun setRenderInfoCollection(renderInfoCollection: LayoutInfo.RenderInfoCollection?)
