By clicking on the item in the list and get the position where you click, you only take your user data with putExtra , and then within the other Activity with the user's data, you can already modify what you want To modify the user that you are clicking, you will have to take the user id of that user and then pass it to the reference that will allow you to do a setValue() or updateValue() in Firebase

For example the following snippet

mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                            @Override
                            public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
                                try{
                                    mDatabase = mAdapter.getRef(position);
                                    Intent intent = new Intent(MainActivity.this, UserEdit.class);
                                    intent.putExtra("uid",mDatabase.getKey());
                                    intent.putExtra("Nombre", mAdapter.getItem(position).getNombre());
                                    intent.putExtra("Email", mAdapter.getItem(position).getEmail());
                                    intent.putExtra("Pago", mAdapter.getItem(position).getPago());
                                    intent.putExtra("UConexion", mAdapter.getItem(position).getUConexion());
                                    intent.putExtra("PConexion", mAdapter.getItem(position).getPConexion());
                                    startActivity(intent);
                                }catch (Exception e){
                                    e.printStackTrace();
                                }
                            }
                        });

and then in your other Activity you get that extra and you work with the data of that user, you are going through extra, it is the uid of the user that you want to modify the data in the other Activity

 Intent iin= getIntent();
        Bundle b = iin.getExtras();

        if(b!=null)
        {

            String n =(String) b.get("Nombre");
            final String e =(String) b.get("Email");
            String p =(String) b.get("Pago");
            String Uconexion =(String) b.get("UConexion");
            String PConexion =(String) b.get("PConexion");
            String Dispositivo =(String) b.get("Dispositivo");
            uid =(String) b.get("uid");


            mDatabase.child("Usuarios").child(uid).child("turef").addValueEventListener(new ValueEventListener() {
                final List<String> LstIdioma = new ArrayList<String>();

                @Override
                public void onDataChange(final DataSnapshot dataSnapshot) {

                  //obtene los datos del usuario por ej

                    }

This is a snippet of a code of mine, but it serves you in the same way as you need
