): Int
Provides a chance to change where the Pager
fling will settle.
Parameters
startPage | The current page right before the fling starts. |
suggestedTargetPage | The proposed target page where this fling will stop. This target will be the page that will be correctly positioned (snapped) after naturally decaying with velocity using a DecayAnimationSpec . |
velocity | The initial fling velocity. |
pageSize | The page size for this Pager in pixels. |
pageSpacing | The spacing used between pages in pixels. |
Returns
