后台只返回一个list集合让我去分页，好蛋疼，后来发现也很简单，使用list的一个方法subList搞定！

关键代码：

//展示具体描述 private void initViewPager(List list) { int count = 4;  int sp = list.size() / 4;  for (int i = 0; i < sp; i++) {
        List subList = list.subList(i * count, count * (i + 1));  sublists.add(subList);  } int s = list.size() % 4;  if (s != 0) {
        List subList = list.subList(list.size() - s, list.size());  sublists.add(subList);  } pagerList.clear();  for (int i = 0; i < sublists.size(); i++) { pagerList.add(new SpecificdescriPager(SpecificdescriptionActivity.this, sublists.get(i)));   }
    initDot();  vpViewPager.setAdapter(new MyPagerAdapter());  vpViewPager.setCurrentItem(0);//默认给Viewpager设置选中的页数  updateDesAndDot();//初始化第0页的描述和点  vpViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { @Override  public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        } @Override  public void onPageSelected(int position) {
            updateDesAndDot();  } @Override  public void onPageScrollStateChanged(int state) {
        }
    }); }
