问题描述
我的活动A，B，C中有3个片段。该流程是A-> B，B-> C，C-> B，A后退按下app退出，B后退按下app退出。我有一个自动注销功能，它采用片段C-> A但在此之后按回按钮时片段A移动到C而不是App退出。我使用下面的代码来自C-> A Fragment。我希望当我来自C-> A并按下后退按钮时应该退出应用程序。
FragmentTransaction fragmentTransaction = getActivity（）。getSupportFragmentManager（）。beginTransaction（ ）;
fragmentTransaction.replace（R.id.frameLayout_main，ApplicationConstants.loginFragment）;
fragmentTransaction.addToBackStack（null）;
// fragmentTransaction.commit（）;
fragmentTransaction.commitAllowingStateLoss（）;
I have 3 fragments in my activity A,B,C. The flow is A->B,B->C,C->B, A Back pressed app exit,B back pressed app exit. I have an auto logout feature which took fragment C->A but after that when press back button the fragment A moves to C instead of App exit. i have used the below code to go from C->A Fragment. I want when i come from C->A and press back button the application should be exited.
FragmentTransaction fragmentTransaction = getActivity().getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.frameLayout_main, ApplicationConstants.loginFragment);
fragmentTransaction.addToBackStack(null);
//fragmentTransaction.commit();
fragmentTransaction.commitAllowingStateLoss();
