Observable

public interface Observable

Known Indirect Subclasses BaseObservable, ObservableBoolean, ObservableByte, ObservableChar, ObservableDouble, ObservableField<T>, ObservableFloat, ObservableInt, ObservableLong, ObservableParcelable<T extends Parcelable>, ObservableShort, ViewDataBinding BaseObservable A convenience class that implements Observable interface and provides notifyPropertyChanged(int) and notifyChange() methods.  ObservableBoolean An observable class that holds a primitive boolean.  ObservableByte An observable class that holds a primitive byte.  ObservableChar An observable class that holds a primitive char.  ObservableDouble An observable class that holds a primitive double.  ObservableField<T> An object wrapper to make it observable.  ObservableFloat An observable class that holds a primitive float.  ObservableInt An observable class that holds a primitive int.  ObservableLong An observable class that holds a primitive long.  ObservableParcelable<T extends Parcelable> An observable class that holds a parcelable object.  ObservableShort An observable class that holds a primitive short.  ViewDataBinding Base class for generated data binding classes.

Observable classes provide a way in which data bound UI can be notified of changes. ObservableList and ObservableMap also provide the ability to notify when changes occur. ObservableField, ObservableParcelable, ObservableBoolean, ObservableByte, ObservableShort, ObservableInt, ObservableLong, ObservableFloat, and ObservableDouble provide a means by which properties may be notified without implementing Observable.

An Observable object should notify the Observable.OnPropertyChangedCallback whenever an observed property of the class changes.

The getter for an observable property should be annotated with Bindable.

Convenience class BaseObservable implements this interface and PropertyChangeRegistry can help classes that don't extend BaseObservable to implement the listener registry.
