android SharedPreferences putStringSet order/sort
android, save, sharedpreferences
Solution
This is not possible. Sets are unordered collections.
Problem
I try to save/restore a set of string and all is working except one thing. When i create my strings i put : ``` Set<String> set = new HashSet<String>(); for(int i=0; i<toggles.size();i++){ set.add(toggles.get(i).serialise()); } ``` Order is for example "blutooth" "application" "data". When i get back set : ``` Set<String> set = prefs.getStringSet(key, new HashSet<String>()); for (String toggle : set){ Toggle t = new Toggle(); t.deserialize(toggle); toggles.add(t); } ``` I get "application" "bluetooth" "data" they are sort by name and i don't want this. I want to get same order i have save. Anyone can help me ?
