How to get all keys of SharedPreferences programmatically in Android?

Question

How to get all keys in SharedPreferences, not the value of the preference just key only?

prefA = getSharedPreferences("MyAttack", MODE_PRIVATE); prefB= getSharedPreferences("MySkill", MODE_PRIVATE); 

Answer 1

SharedPreferences has the method getAll() that returns a Map<String, ?> . From the Map you can retrieve easily the keys with keySet() and the key/value mappings with entrySet():

Map<String, ?> allEntries = prefA.getAll(); for (Map.Entry<String, ?> entry : allEntries.entrySet()) {     Log.d("map values", entry.getKey() + ": " + entry.getValue().toString()); }
