Java 我有一个SlidingTableOut并且我一直得到这个运行时异常？

我已经设置了一个滑动选项卡布局，在选项卡之间切换时，我一直会遇到这个运行时异常。我不知道这到底意味着什么，有人能解释一下情况吗

我对问题进行了更新，使其更具信息性。

正如您的例外情况所述： java.lang.RuntimeException:com.athena.athena.MainActivitys。MainActivity@42988d90必须实现OnFragmentInteractionListener

您可以检查MainActivity是否正在实现FragmentInteractionListener类吗？

您还需要发布代码。另外，问题是，当我单击myRecent时，它会将我带到标记页面，并告诉我如何实现我的Listener为什么我的标记活动会影响我最近的活动？请检查以下内容：
