xyz.eraise.bannerview.loopviewpager.LoopViewPager

public class LoopViewPager
extends ViewPager

无限滚动的ViewPager A ViewPager subclass enabling infinte scrolling of the viewPager elements When used for paginating views (in opposite to fragments), no code changes should be needed only change xml's from to If "blinking" can be seen when paginating to first or last view, simply call seBoundaryCaching( true ), or change DEFAULT_BOUNDARY_CASHING to true When using a FragmentPagerAdapter or FragmentStatePagerAdapter, additional changes in the adapter must be done. The adapter must be prepared to create 2 extra items e.g.: The original adapter creates 4 items: [0,1,2,3] The modified adapter will have to create 6 items [0,1,2,3,4,5] with mapping realPosition=(position-1)%count [0->3, 1->0, 2->1, 3->2, 4->3, 5->0]
