我的应用程序时使用意向另一个活动推出的导航栏活动崩溃。应用程序强制关闭在启动导航栏活动
我有一个名为访客登录按钮，其中有推出的导航栏的活动。但是，点击该按钮后，该应用程序会强制关闭。
我是很新的导航栏的活动。有人能告诉我我在这里犯了什么错误吗？

你能告诉我你创建的片段是什么意思吗？ –
你需要通过从Fragment类扩展它来创建一个片段，就像这样'public class YourFragment extends Fragment {}'。阅读更多https://developer.android.com/training/basics/fragments/fragment-ui.html –
