I'm new to Firebase. I want to add Firebase specific data to my spinner. I view this content This help content, but I don't get it

i would like to fetch the username into my spinner.

My code

private void showdata()
{
    spinnerRef.child("Users").addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot snapshot) {
            for(DataSnapshot item:snapshot.getChildren())
            {
                spinnerList.add((item.child("username").getValue()).toString());
            }
            adapter.notifyDataSetChanged();
        }

        @Override
        public void onCancelled(@NonNull DatabaseError databaseError) {

        }
    });
}

Okay, you have any errors? – Ticherhaz FreePalestine Jan 04 '22 at 03:03
@TicherhazFreePalestine I don't have errors encountering so far – Koykoy200078 Jan 04 '22 at 03:04
So, the data cannot retrieve? – Ticherhaz FreePalestine Jan 04 '22 at 03:15
@TicherhazFreePalestine Yes : – Koykoy200078 Jan 04 '22 at 03:28

First step is to stop ignoring errors. At its minimum, `onCancelled` should be `public void onCancelled(@NonNull DatabaseError databaseError) { throw databaseError.toException(); }`. – Frank van Puffelen Jan 04 '22 at 04:08

As also Frank van Puffelen mentioned in his comment, first of all, stop ignoring errors. Use `Log.d(TAG, error.getMessage());`. Do you get something printed out in the logcat? Please also respond with @. – Alex Mamo Jan 04 '22 at 09:56
@Koykoy200078 have you solved the problem? – Ticherhaz FreePalestine Jan 06 '22 at 06:18
