如何通过通知将Android现有活动带到前面

Intent intent = new Intent(this, YourActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
fragmentManager.beginTransaction()
        .replace(R.id.container, newFragment)
        .addToBackStack(null)
        .commit();

NavController navController = findNavController(R.id.nav_host_fragment);
navController.popBackStack(R.id.startDestination, false);
navController.navigate(R.id.action_global_yourFragment);
