How To Read Childrens From A Firebase Database Using Firebaselistadapter In Java?

I am very new in Firebase. So, i have a database structure like this: and want to display those generated id's into a listview. I'm using FirebaseListAdapter. Here is my code:

Solution 1:

Change the populateView method implementation to

firebaseListAdapter = newFirebaseListAdapter<User>(this, User.class, android.R.layout.simple_list_item_1, databaseReference) {
    @OverrideprotectedvoidpopulateView(View v, User user, int position) {
        TextViewtextView= (TextView) v.findViewById(android.R.id.text1);
        StringuserKey=this.getRef(position).getKey();
        textView.setText(userKey);
    }
};

Solution 2:

You'll need a FirebaseListAdapter<Map> instead of FirebaseListAdapter<String>. Your code would become something like this (didn't compile it though, that's up to you ;-)

databaseReference = FirebaseDatabase.getInstance().getReference().child("Firebase").child("Users");
firebaseListAdapter = newFirebaseListAdapter<Map>(this, Map.class, android.R.layout.simple_list_item_1, databaseReference) {
    @OverrideprotectedvoidpopulateView(View v, Map users, int position) {
        TextView textView = (TextView) v.findViewById(android.R.id.text1);
        textView.setText(users.getKey());
    }
};
listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(firebaseListAdapter);
