How to save and retrieve data using SharedPreferences in Android
Create SharedPreferences:
SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", MODE_PRIVATE);
Editor editor = pref.edit();
Storing data as KEY/VALUE pair:
editor.putBoolean("key_name1", true); // Saving boolean - true/false
editor.putInt("key_name2", "int value"); // Saving integer
editor.putFloat("key_name3", "float value"); // Saving float
editor.putLong("key_name4", "long value"); // Saving long
editor.putString("key_name5", "string value"); // Saving string
// Save the changes in SharedPreferences
editor.apply(); // commit changes
Get SharedPreferences data:
// If value for key not exist then return second param value - In this case null
boolean userFirstLogin= pref.getBoolean("key_name1", true); // getting boolean
int pageNumber=pref.getInt("key_name2", 0); // getting Integer
float amount=pref.getFloat("key_name3", null); // getting Float
long distance=pref.getLong("key_name4", null); // getting Long
String email=pref.getString("key_name5", null); // getting String
Deleting Key value from SharedPreferences:
editor.remove("key_name3"); // will delete key key_name3
editor.remove("key_name4"); // will delete key key_name4
// Save the changes in SharedPreferences
editor.apply(); // commit changes
Clear all data from SharedPreferences
editor.clear();
editor.apply(); // commit changes
