In this, you can see how to fetch each of the node values then key along with their values.

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

        for (DataSnapshot childDataSnapshot : dataSnapshot.getChildren()) {

         //"It will give you all node values:"+dataSnapshot.getKey()
        //"You can check ": 

          if(dataSnapshot.getKey()=="amitpal"){
            for (DataSnapshot childDataSnapshot2 : childDataSnapshot.getChildren()) {

         // "CHILD KEY"+childDataSnapshot2.getKey()

                arrayList.add(childDataSnapshot2.getKey());

         //"CHILD VALUES"+childDataSnapshot2.getValue()

            }}

            }

    }
    @Override
    public void onCancelled(DatabaseError databaseError) {

    }
});
