ObservableFloat

public class ObservableFloat
extends BaseObservable implements Parcelable, Serializable

An observable class that holds a primitive float.

Observable field classes may be used instead of creating an Observable object. It can also create a calculated field, depending on other fields:

public class MyDataObject { public final ObservableFloat temperatureC = new ObservableFloat(); public final ObservableFloat temperatureF = new ObservableFloat(temperatureC) { @Override public float get() { return (temperatureC.get() * 9 / 5) + 32; } }; }

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. A parceled ObservableField will lose its dependencies.
