一个对象包装,使其可观察。
可以使用Observable字段类来代替创建Observable对象:
public class MyDataObject {
public final ObservableField<String> name = new ObservableField<String>();
public final ObservableInt age = new ObservableInt();
}
Fields of this type should be declared final because bindings only detect changes in the field's value, not of the field itself.
