public class ObservableFloat extends BaseObservable implements Parcelable, Serializable
Observable field classes may be used instead of creating an Observable object:
public class MyDataObject {
public final ObservableFloat temperature = new ObservableFloat();
}
Fields of this type should be declared final because bindings only detect changes in the
field's value, not of the field itself.
This class is parcelable and serializable but callbacks are ignored when the object is parcelled / serialized. Unless you add custom callbacks, this will not be an issue because data binding framework always re-registers callbacks when the view is bound.
