Functions

add

open override fun add(renderInfo: RenderInfo, width: Int, height: Int)

This will be called to inform implementations that the next layout has been computed. Implementations should use the width/height to determine whether they still need more views to fill their initial viewport (which should be reflected in the next call to wantsMore

getFill

open override fun getFill(): Int

Return the fill along the main axis (i.e. height for VERTICAL and width for HORIZONTAL), this method is available after ViewportFiller.add is called.

wantsMore

open override fun wantsMore(): Boolean

Implementations should return true if they need more views to be computed in order to fill the screen.
