ObservableField

public class ObservableField
extends BaseObservable implements Serializable

Known Direct Subclasses ObservableParcelable<T extends Parcelable> ObservableParcelable<T extends Parcelable> An observable class that holds a parcelable object.

An object wrapper to make it observable.

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 {
     private Context context;
     public final ObservableField<String> first = new ObservableField<String>();
     public final ObservableField<String> last = new ObservableField<String>();
     public final ObservableField<String> display =
         new ObservableField<String>(first, last) {
             @Override
             public String get() {
                 return context.getResources().getString(R.string.name, first.get, last.get());
             }
         };
     public final ObservableInt age = new ObservableInt();
 }
