You'll have to sort an arrayList by overridding the comparator to match your requirements. — Alexandre BOURETZ, Sep 14 '17 at 10:30

String values are sorted lexicographically. If you want them to be sorted in the order you want, you'll need to ensure that the lexicographical order matches your needs, e.g. pad the numbers in your keys to all be the same length:

"value01": ...
..
"value09": ...
"value10": ...

I wrote a longer answer on this a while ago, see: Firebase query ordering not working properly
