Getting all meanings of field in ArrayList | Firebase

Question

I am using Firebase Realtime database in my Android app. How can I query field Ingridients in my database and get all meanings in ArrayList

Answer 1

DatabaseReference recept = FirebaseDatabase.getInstance().getReference("Receptes");
DatabaseReference vegies = recept.child("Ingridients");

Check the documentation for more explanation.

You also need to add a listener

recept.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        Log.i(TAG, dataSnapshot.child("Ingredients").getValue(String.class);
    }

    @Override
    public void onCancelled(DatabaseError databaseError) {
        Log.w(TAG, "onCancelled", databaseError.toException());
    }
});
