如何以编程方式在ViewPager中显示下一个视图？

我创build了一个ViewPager，一切工作正常，但是我想有一个以前的ViewPager之外的下一个button，可以在ViewPager中导航。 我怎样才能去ViewPager的下一个项目，而无需手动刷卡？

Answer 1

由于blessenm回答了viewpager.setCurrentItem(int index)是要走的路。

Answer 2

一个完整的实现只是为了完整性：

 public void MoveNext(View view) { //it doesn't matter if you're already in the last item pager.setCurrentItem(pager.getCurrentItem() + 1); } public void MovePrevious(View view) { //it doesn't matter if you're already in the first item pager.setCurrentItem(pager.getCurrentItem() - 1); } 

Answer 3

我更好地解决它，安德森森。

  private void MoveNextTopSlideShow(View view) { if (_viewPager_TopImageSlide.CurrentItem == _viewPager_TopImageSlide.ChildCount) { if (_viewPager_TopImageSlide.ChildCount > 0) { _viewPager_TopImageSlide.SetCurrentItem(0,true); } } else { //it doesn't matter if you're already in the last item _viewPager_TopImageSlide.SetCurrentItem(_viewPager_TopImageSlide.CurrentItem + 1, true); } } private void MovePreviousTopSlideShow(View view) { if (_viewPager_TopImageSlide.CurrentItem == 0) { if (_viewPager_TopImageSlide.ChildCount > 0) { _viewPager_TopImageSlide.SetCurrentItem(_viewPager_TopImageSlide.ChildCount-1, true); } } else { //it doesn't matter if you're already in the first item _viewPager_TopImageSlide.SetCurrentItem(_viewPager_TopImageSlide.CurrentItem - 1, true); } }
