我想创建一个ViewPager（有三个项目），其中每个视图是另一个ViewPager（两个项目）。用户然后轻扫像这样的项目：

I would like to create a ViewPager (with three items) where each of its view is another ViewPager (with two items). User then swipe items like this:

ViewPager1[0] ViewPager2[0]
ViewPager1[0] ViewPager2[1]
ViewPager1[1] ViewPager2[0]
ViewPager1[1] ViewPager2[1]
ViewPager1[2] ViewPager2[0]
ViewPager1[2] ViewPager2[1]

怎么会是这样可能吗？

How would that be possible?

推荐答案

在父ViewPager覆盖canScroll：

override canScroll in the parent ViewPager:

@Override
protected boolean canScroll(View v, boolean checkV, int dx, int x, int y) {
   if(v != this && v instanceof ViewPager) {
      return true;
   }
   return super.canScroll(v, checkV, dx, x, y);
}
