How can I pass a string to Activity coming from Adapter to Fragment then to Activity

How can I pass data to activity from Adapter to Fragment then to Activity

This is my Adapter

Bundle bundle = new Bundle();
            bundle.putString("title01", title);
            bundle.putString("amount", Video1);
            bundle.putString("title", chat_ID);
            bundle.putString("desc", video_desc);
            Navigation.findNavController(v).navigate(R.id.action_global_frag_videoplay, bundle);

This is my Fragment

String str = getArguments().getString("amount");
Intent intent = new Intent(getActivity(), FullscreenActivity.class);
                intent.putExtra("key1", str);;
                startActivity(intent);

This is my activity

  String value = intent.getStringExtra("key1");

Keep getting this error when activity opens
