SharedPreferences in Android is a way to store key-value pairs of primitive data types. It's ideal for saving small amounts of data, like user preferences or settings. Here's a breakdown of how to use it:
Obtain SharedPreferences Object:
SharedPreferences sharedPref = getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
getSharedPreferences() retrieves the SharedPreferences object. The first argument is the name of the preference file (a string). Context.MODE_PRIVATE makes the file private to your application.Editor Object for Modification:
SharedPreferences.Editor editor = sharedPref.edit();
Editor object is needed to make changes to the SharedPreferences.Storing Data:
editor.putString("username", "john_doe");
editor.putInt("user_id", 12345);
editor.putBoolean("loggedIn", true);
editor.putFloat("user_score", 98.5f);
editor.putLong("timestamp", System.currentTimeMillis());
put methods based on the data type. You can chain multiple put calls.Applying Changes:
editor.apply(); // or editor.commit();
apply() asynchronously commits changes, while commit() does it synchronously. apply() is generally preferred for better performance.Retrieving Data:
String username = sharedPref.getString("username", ""); // Default value is empty string
int userId = sharedPref.getInt("user_id", 0); // Default value is 0
boolean loggedIn = sharedPref.getBoolean("loggedIn", false); // Default value is false
float userScore = sharedPref.getFloat("user_score", 0.0f); // Default value is 0.0f
long timestamp = sharedPref.getLong("timestamp", 0L); // Default value is 0L
Example: Saving and Loading a User's Name
SharedPreferences sharedPref = getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putString("userName", "Jane Doe");
editor.apply();
String userName = sharedPref.getString("userName", "");
// userName will now contain "Jane Doe"
Simple Explanation:
SharedPreferences lets you save simple data like user settings easily. Get a SharedPreferences object, use an editor to add/change values (using putString, putInt, etc.), then apply or commit the changes. Retrieve values later using getString, getInt, etc., and provide default values.
