Question

我查看了有关类似问题的堆栈溢出的所有问题，但没有设法找到解决方案，这适合我的情况。

我需要实现以下结构：片段A正在被片段B替换。片段B包含ViewPager，它切换片段C1和C2。如果我从支持库使用ViewPager，这很有效，但问题是，我需要一个ViewPager来使用垂直滑动。为此，我正在使用Jake Wharton的图书馆https://stackoverflow.com/a/14268702/1220743。

一些代码：

A正在被B

取代

Fragment fragment = new FragmentB();
String tag = this.getClass().getName();
FragmentManager fm = getFragmentManager();
fm.beginTransaction().replace(R.id.container, fragment).addToBackStack(tag).commit();

B初始化DirectionalViewPager

DirectionalViewPager viewPager = (DirectionalViewPager)v.findViewById(R.id.view_pager);
FragmentManager fm = getFragmentManager();
viewPager.setAdapter(new MyViewPagerAdapter(fm));

当A切换到B时，这会让我崩溃，后面是崩溃堆栈：

有没有人遇到过类似的问题？

Answer 1

您有没有找到解决方案？已经在片段中的两个片段？若是这样使用getChildFragmentManager（）对我来说好奇的是，getFragmentManager看起来好像你没有使用支持v4，或者它是getSupportFragmentManager没有？但是通过日志，当您使用支持库时，似乎发生了错误。

尝试使用DirectionalViewPager时崩溃（由Jake Wharton提供）
