How to store a boolean value using SharedPreferences in Android?
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(); Boolean statusLocked = prefs.edit().putBoolean("locked", true).commit();if you dont care about the return value (status) then you should use .apply() which is faster because its asynchronous.
prefs.edit().putBoolean("locked", true).apply();to get them back use
Boolean yourLocked = prefs.getBoolean("locked", false);while false is the default value when it fails or is not set
In your code it would look like this:
boolean locked = true;SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(); if (locked) { //maybe you want to check it by getting the sharedpreferences. Use this instead if (locked)// if (prefs.getBoolean("locked", locked) { prefs.edit().putBoolean("locked", true).commit();} else { startActivity(new Intent(parent.getContext(), Tag1.class));}
