Rx Preferences

Reactive SharedPreferences for Android.

Usage

Create an RxSharedPreferences instance which wraps a SharedPreferences:

SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
RxSharedPreferences rxPreferences = RxSharedPreferences.create(preferences);

Hint: Keep a strong reference on your RxSharedPreferences instance for as long as you want to observe them to prevent listeners from being GCed.

Create individual Preference objects:

Preference<String> username = rxPreferences.getString("username");
Preference<Boolean> showWhatsNew = rxPreferences.getBoolean("show-whats-new", true);

Observe changes to individual preferences:

username.asObservable().subscribe(new Action1<String>() {
  @Override public void call(String username) {
    Log.d(TAG, "Username: " + username);
  }
}

Subscribe preferences to streams to store values:

RxCompoundButton.checks(showWhatsNewView)
    .subscribe(showWhatsNew.asConsumer());

(Note: RxCompoundButton is from RxBinding)
