最佳答案

作为祝福回答 viewpager.setCurrentItem(int index)是走的方式。

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);
}

我会修好的 Ty Androiderson。

  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);
}
}

最简单的方法是:

nextButton.setOnClickListener { pager.arrowScroll(View.FOCUS_RIGHT) }
prevButton.setOnClickListener { pager.arrowScroll(View.FOCUS_LEFT) }
