Link for firebase data - https://fireui-78226.firebaseio.com/Users
Libraries used -

As it's a public but still it's not updating the list view. Any help would be great.
ListView listView;
DatabaseReference ref;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = findViewById(R.id.listView);
ref = FirebaseDatabase.getInstance().getReferenceFromUrl("https://fireui-78226.firebaseio.com/Users");
Query query = FirebaseDatabase.getInstance().getReferenceFromUrl("https://fireui-78226.firebaseio.com/Users");
FirebaseListOptions<String> options = new FirebaseListOptions.Builder<String>()
.setQuery(query, String.class)
.setLayout(android.R.layout.simple_list_item_1)
.build();
FirebaseListAdapter<String> firebaseListAdapter = new FirebaseListAdapter<String>(options) {
@Override
protected void populateView(View v, String model, int position) {
TextView textView = v.findViewById(android.R.id.text1);
textView.setText(model);
}
};
listView.setAdapter(firebaseListAdapter);
}
}
