ObservableFloat

public class ObservableFloat
extends BaseObservable implements Parcelable, Serializable

java.lang.Object
↳	android.databinding.BaseObservable
	↳	android.databinding.ObservableFloat

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; }
     };
 }

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. A parceled ObservableField will lose its dependencies.
