Pref.getLong("key_name", null) // getting Long
Pref.getFloat("key_name", null) // getting Float Pref.getInt("key_name", -1) // getting Integer
Pref.getString("key_name", null) // getting String SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0) // 0 - for private modeĮmit() is used in order to save changes to shared preferences.Įditor.putBoolean("key_name", true) // Storing boolean - true/falseĮditor.putString("key_name", "string value") // Storing stringĮditor.putInt("key_name", "int value") // Storing integerĮditor.putFloat("key_name", "float value") // Storing floatĮditor.putLong("key_name", "long value") // Storing longĭata can be retrieved from saved preferences by calling getString() as follows:
The following code can be used to get the shared preferences. We need an editor to edit and save the changes in shared preferences. When it is set, it would enable write ahead logging by default MODE_ENABLE_WRITE_AHEAD_LOGGING: Database open flag.MODE_APPEND: This will append the new preferences with the already existing preferences.MODE_MULTI_PROCESS: This method will check for modification of preferences even if the Shared Preference instance has already been loaded.MODE_WORLD_WRITEABLE: Creating world-writable files is very dangerous, and likely to cause security holes in applications.MODE_WORLD_READABLE: Creating world-readable files is very dangerous, and likely to cause security holes in applications.MODE_PRIVATE: the default mode, where the created file can only be accessed by the calling application.GetSharedPreferences (String PREFS_NAME, int mode)įollowing are the operating modes applicable: In this tutorial we’ll go with getSharedPreferences(). getDefaultSharedPreferences() : used on the PreferenceManager, to get the shared preferences that work in concert with Android’s overall preference framework.getSharedPreferences() : used from within your Activity (or other application Context), to access application-level preferences.getPreferences() : used from within your Activity, to access activity-specific preferences.
