Assuming that you have implemented Firebase authentication and Adultos node is a direct child of your Firebase root, to get those keys, please use the following code:

String uid = FirebaseAuth.getInstance().getCurrentUser().getUid();

DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
DatabaseReference uidRef = rootRef.child("Adultos").child(uid);
ValueEventListener valueEventListener = new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        for(DataSnapshot ds : dataSnapshot.getChildren()) {
            String key = ds.getKey();
            Log.d("TAG", key);
        }
    }

    @Override
    public void onCancelled(DatabaseError databaseError) {}
};
uidRef.addListenerForSingleValueEvent(valueEventListener);

Te output in your logcat will be all those pushed ids highlighted in red.

  • Can i use that on my RecyclerView? Because i want get data from push and list that – Gabriel Nogueira Aug 01 '18 at 12:35
  • Yes you can. **[This](https://stackoverflow.com/questions/49383687/how-can-i-retrieve-data-from-firebase-to-my-adapter/49384849)** is a recommended way in which you can retrieve data from a Firebase Realtime database and display it in a `RecyclerView` using `FirebaseRecyclerAdapter`. – Alex Mamo Aug 01 '18 at 12:44
  • Thanks a lot , i will follow all your steps and return your post. – Gabriel Nogueira Aug 01 '18 at 12:52
  • So , i follow all steps but my recycleView empty now – Gabriel Nogueira Aug 01 '18 at 13:35
  • Let's stick to one question at a time. Have you got the ids using my above code? – Alex Mamo Aug 01 '18 at 13:39
  • The issue regarding the `RecyclerView` is basically another question that I cannot answer in a comment and without the necessary code and in order to follow the rules of this comunity, please post another fresh question, so me and other users can help you. – Alex Mamo Aug 01 '18 at 13:42
