问题描述
我有一个employeeList片段，该片段在访问时使应用程序崩溃.代码中没有波浪线，堆栈跟踪中也没有任何警报.我有一种预感，scrollView可能是造成这种情况的原因.这是代码
I have an employeeList fragment which upon access crashes the app. There are no squiggly lines in code, neither any alarms in the stack trace. I have a hunch that scrollView might be causing this. Here's the code

推荐答案
替换:
FragmentTransaction ft = getFragmentManager().beginTransaction();
使用:
FragmentTransaction ft = getChildFragmentManager().beginTransaction();
