A small library containing a wrapper/helper for the shared preferences of Android.
With this library you can initialize the shared preference inside the onCreate of the Application class of your app.
public class PrefsApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
// Initialize the Prefs class
new Prefs.Builder()
.setContext(this)
.setMode(ContextWrapper.MODE_PRIVATE)
.setPrefsName(getPackageName())
.setUseDefaultSharedPreference(true)
.build();
}
}After initialization, you can use simple one-line methods to save values to the shared preferences anywhere in your app, such as:
Prefs.putString(key, string)Prefs.putLong(key, long)Prefs.putBoolean(key, boolean)
Retrieving data from the Shared Preferences can be as simple as:
String data = Prefs.getString(key, default value)
If the shared preferences contains the key, the string will be obtained, otherwise the method returns the default string provided. No need for those pesky contains() or data != null checks!
For some examples, see the sample App.
The default implementation of getStringSet on Android does not preserve the order of the strings in the set. For this purpose, EasyPrefs adds the methods:
void Prefs.putOrderedStringSet(String key, Set<String> value);
and
Set<String> Prefs.getOrderedStringSet(String key, Set<String> defaultValue);
which internally use Java's LinkedHashSet to retain a predictable iteration order. These methods have the added benefit of adding the missing functionality of storing sets to pre-Honeycomb devices.
