It seems you are using the new Firebaseui (version 3.0+), the constructor of the FirebaseListAdapter was changed.
First, you need to configure the adapter by using the class FirebaseListOptions, then you can create an instance of FirebaseListAdapter.
Check this code from the docs:
FirebaseListOptions<Chat> options = new FirebaseListOptions.Builder<Chat>()
.setQuery(query, Chat.class)
.build();
FirebaseListAdapter<Chat> adapter = new FirebaseListAdapter<Chat>(options) {
@Override
protected void populateView(View v, Chat model, int position) {
// Bind the Chat to the view
// ...
}
};
As you can see the FirebaseListAdapter takes a parameter of type FirebaseListOptions
More info here:
https://github.com/firebase/FirebaseUI-Android/blob/master/database/README.md#using-firebaseui-to-populate-a-listview
You can see the source code here:
https://github.com/firebase/FirebaseUI-Android/blob/master/database/src/main/java/com/firebase/ui/database/FirebaseListAdapter.java
