Insert data and "primary key" in Firebase

Navigation
2

Good morning,

I'm starting with programming, and I have the following question. 1. I can enter data in the firebase, but when I try to insert it again, only replacing the data occurs instead of inserting the new record.

  • How can I enter data in the firebase together with the "primary key"? (field highlighted in the image, it's just to display the field I want, it's not my bank in the firebase).

    • Imageofbankonfirebasewithfield"primary key" Hugs.

    Try this. 

    DatabaseReference mDatabase = FirebaseDatabase.getInstance().getReference();
 mDatabase.child("tasks").push().setValue(firebaseData, new DatabaseReference.CompletionListener() {
        @Override
        public void onComplete(DatabaseError databaseError, DatabaseReference databaseReference) {
            //Problem with saving the data
            if (databaseError != null) {

            } else {
                //Data uploaded successfully on the server

               }

            }
    });
