Reading from a simple FireBase Database

Question

I\'m having some issues reading from a Firebase Database.

I have a pretty simple layout

{
  \"lot\" : {
    \"lot1\" : \"low\",
    \"lot2\" : \"low\",
          


        

Answer 1

I had the same question and this is what i used. Modifying to fit the question here

private List lotList;

lotList = new ArrayList<>();

DatabaseReference reference= database.getInstance().getReference().child("lot");

Now adding value event listener

reference.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {

            Iterable mData = dataSnapshot.getChildren();

            for(DataSnapshot d : mData){

                String lot_string = d.getValue(String.class);
                lotList.add(lot_string);
            }
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });
