<\/span><\/h2>\nTo retrieve a value from SharedPreferences in Android, follow these steps:<\/p>\n
1. Get the reference to SharedPreferences:<\/strong> Start by obtaining a reference to the SharedPreferences object using the `getSharedPreferences()` method. This method requires the name of the SharedPreferences file and the mode (usually MODE_PRIVATE).<\/p>\n2. Retrieve the value:<\/strong> Once you have the SharedPreferences object, you can retrieve the stored value using the appropriate getter method based on the data type you used to store the value.<\/p>\nLet’s take a look at an example. Suppose we have stored a boolean value with the key “isDarkMode” in SharedPreferences, and now we want to retrieve its value.<\/p>\n
“`java
\n\/\/ Get the reference to SharedPreferences
\nSharedPreferences sharedPreferences = getSharedPreferences(“myPrefs”, MODE_PRIVATE);<\/p>\n
\/\/ Retrieve the boolean value
\nboolean isDarkMode = sharedPreferences.getBoolean(“isDarkMode”, false);
\n“`<\/p>\n
In the above code snippet, we first obtain the reference to the SharedPreferences object named “myPrefs” using the `getSharedPreferences()` method. Then, we retrieve the boolean value associated with the key “isDarmMode” using the `getBoolean()` method with a default value of `false`. If the key doesn’t exist, it will return the default value.<\/p>\n
Note:<\/strong> It’s important to specify a default value that matches the expected data type when retrieving values from SharedPreferences. This value will be returned if the requested key doesn’t exist.<\/p>\n
