用於連續滾動的Circular ViewPager

Question

我正在顯示僅包含ImageViews的ViewPager。但是，我需要它以循環的方式不斷髮生。對於防爆：... C> B> A> B> C ...

Answer 1

只需實現ViePager.OnPageChangeListener：

YOUR_VIEWPAGER.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { 
    @Override 
    public void onPageSelected(int position) { 
     currentPage = position; 
    } 
    @Override 
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { 
     // not needed 
    } 
    @Override 
    public void onPageScrollStateChanged(int state) { 
     if (state == ViewPager.SCROLL_STATE_IDLE) { 
     int pageCount = pages.size(); 

     if (currentPage == 0){ 
      YOUR_VIEWPAGER.setCurrentItem(pageCount-2,false); 
     } else if (currentPage == pageCount-1){ 
      YOUR_VIEWPAGER.setCurrentItem(1,false); 
     } 
     } 
    } 
    });
