How to display User in ListView in Fragment from Firebase?

I have an app with user login, there is basic data such as Name, email,Age etc. but i want to display only 2 data for each user in a list view. Im pretty much a beginner in using ListView so i dont know where to start. Especially when Im using Fragment:

My code here: 

     @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (getArguments() != null) {
        mParam1 = getArguments().getString(ARG_PARAM1);
        mParam2 = getArguments().getString(ARG_PARAM2);
    }

    tutorList = (ListView) getView().findViewById(R.id.tutorListView);

    tutorArrayList = new ArrayList<String>();
    tutorAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, tutorArrayList);

    databaseReference = FirebaseDatabase.getInstance().getReference().getRoot();


    databaseReference.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {


            databaseReference = FirebaseDatabase.getInstance().getReference().child("Users").child("Tutees").child(userID);




        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });
}

I'm also get confused which one to put in onCreate() method or onCreateView() method since im using fragment.

here's my json Structure in firebase:

       "Users" : {
"Tutors" : {

  "daBTEVRQagX7XbwPbXE5X1l3tg62" : {
    "Age" : "22",
    "District" : "miami",
    "Email" : "[email protected]",
    "Name" : "Ainul",
    "Qualification" : "hnd",
    "profileImageUrl" : "https://firebasestorage.googleapis.com/v0/b/tutorpal-1.appspot.com/o/profileImageUrl%2FdaBTEVRQagX7XbwPbXE5X1l3tg62?alt=media&token=a81ccf26-091d-4001-aa23-04665ad27173"
  },
  "glk3Wi1lZZOQkt2UNsGit02DEym2" : {
    "profileImageUrl" : "https://firebasestorage.googleapis.com/v0/b/tutorpal-1.appspot.com/o/profileImageUrl%2Fglk3Wi1lZZOQkt2UNsGit02DEym2?alt=media&token=61192989-93c8-4c55-bca0-9d2b3a6a78fe"
  },
  "yE6ALyKEjVOoNLZcHEvHmeYkqON2" : {
    "FullName" : "hai im ainul ",
    "UserName" : "ainul",
    "profileImageUrl" : "https://firebasestorage.googleapis.com/v0/b/tutorpal-1.appspot.com/o/profileImageUrl%2FyE6ALyKEjVOoNLZcHEvHmeYkqON2?alt=media&token=aa63a6f2-0154-4c27-b7ba-d8de89ee64bc"
  }
}

}

basically i want to access Users-Tutors-Users-all their information

I also want the listview to be set as onclicklistener so whenever user click a user, it will bring to another activity which is the profileActivity of the user. I already have the profileactivity view set but dont know how to do this from a listView to ProfileActivity

First, I suggest you read about FirebaseUI library and try to get examples working

Basically, you're missing a ListView.setAdapter

If you want to have click events, adapter.setOnItemClickListener

I'm also get confused which one to put in onCreate() method or onCreateView() method since im using fragment.

Ideally, only onCreateView returns the inflated View. onViewCreated is where you use findViewById for a Fragment. You cannot call getView from onCreate
