Write multiple items to firebase in Android

I've written an android app using Firebase as the backend. My problem is only one item can be stored in Firebase and when I try to write more data it replaces the existing data. I want to write multiple bits and data and retrieve them in a list view or something.

My Code is below:

public class Capture_Meetings extends AppCompatActivity {

private EditText editTextName;
private EditText editTextAddress;
private EditText editDateTime;
private TextView textViewPersons;
private Button buttonSave;

protected void onCreate(Bundle savedInstanceState) {


buttonSave = (Button) findViewById(R.id.buttonSave);
editTextName = (EditText) findViewById(R.id.editTextName);
editTextAddress = (EditText) findViewById(R.id.editTextAddress);
editDateTime = (EditText) findViewById(R.id.editDateTime);

textViewPersons = (TextView) findViewById(R.id.textViewPersons);

buttonSave.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Creating firebase object
Firebase ref = new Firebase(Config.FIREBASE_URL);

//Getting values to store
String name = editTextName.getText().toString().trim();
String address = editTextAddress.getText().toString().trim();
String DateTime = editDateTime.getText().toString().trim();

//Creating Person object
final MeetingUser person = new MeetingUser();

//Adding values

//Storing values to firebase

//Value event listener for realtime data update
ref.addValueEventListener(new ValueEventListener() {
public void onDataChange(DataSnapshot snapshot)
for (DataSnapshot postSnapshot : snapshot.getChildren()) {
//Getting the data from snapshot
MeetingUser person = postSnapshot.getValue(MeetingUser.class);

//Adding it to a string
String string = "\n Name of School: "+person.getName()+"\n Date:"+ person.getDateTime()+"\nMeeting Notes: "+person.getAddress()+"\n\n";

//Displaying it on textview

public void onCancelled(FirebaseError firebaseError) {
System.out.println("The read failed: " + firebaseError.getMessage());

Have a look at the Firebase documentation. You can use the push method to append data to a node, which will have a unique id.
