The MainActivity.java file is used to save and retrieve the data through keys. The three buttons implement their respective onClicks in the MainActivity. The activity_main.xml layout consists of two EditText views which store and display name and email. Remove(“key_name”) is used to delete that particular value.Įditor.remove("name") // will delete key nameĮditor.remove("email") // will delete key email
PrefEdit, specializing in editing preference plists Property List Tools, an Applescript. Pref.getBoolean("key_name", null) // getting boolean Definitions of Plist, synonyms, antonyms, derivatives of Plist. the most important guests were introduced first The safety of the children has/takes precedence over is. The guests were introduced in order of precedence. Pref.getLong("key_name", null) // getting Long : the condition of being more important than something or someone else and therefore coming or being dealt with first. 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. Stare decisis is a bedrock principle of the American legal system, but it is not an inexorable command.67 The doctrine is a principle of policy and not a mechanical formula of adherence to the latest decision.68 In determining whether to strip a precedent of its binding power, courts balance a number of non-dispositive factors.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().
