ObservableBoolean

public class ObservableBoolean
extends BaseObservable implements Parcelable, Serializable

An observable class that holds a primitive boolean.

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 ObservableBoolean isAdult = new ObservableBoolean();
     public final ObservableBoolean isChild = new ObservableBoolean(isAdult) {
         @Override
         public boolean get() { return !isAdult.get(); }
     };
 }

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 ObservableBoolean will lose its dependencies.
